During the initial phase in early 1942, the Empire of Japan invaded the Territory of New Guinea on 23 January and Territory of Papua on 21 July and overran western New Guinea (part of

234-479: A Mediterranean climate . The south-east ranges from oceanic (Tasmania and coastal Victoria) to humid subtropical (upper half of New South Wales), with the highlands featuring alpine and subpolar oceanic climates . The interior is arid to semi-arid . Driven by climate change , average temperatures have risen more than 1°C since 1960 . Associated changes in rainfall patterns and climate extremes exacerbate existing issues such as drought and bushfires . 2019

351-525: A belt of Brigalow grasslands lie between the coast and the mountains, while inland of the dividing range are large areas of grassland and shrubland. These include the western plains of New South Wales, and the Mitchell Grass Downs and Mulga Lands of inland Queensland. The northernmost point of the mainland is the tropical Cape York Peninsula . The landscapes of the Top End and

468-824: A large wave of immigration from across Europe , with such immigrants referred to as " New Australians ". This required a relaxation of the white Australia policy , which was justified to Australians using the slogan "populate or perish". A member of the Western Bloc during the Cold War , Australia participated in the Korean War and the Malayan Emergency during the 1950s and the Vietnam War from 1962 to 1972. During this time, tensions over communist influence in society led to unsuccessful attempts by

585-598: A considerable natural anchorage and was ideal for the construction of airfields. Over the next year, the Japanese built up the area into a major air and naval base. The Allies responded with multiple bombing raids on Rabaul as well as action off Bougainville . The Japanese Eighth Area Army , under General Hitoshi Imamura at Rabaul, was responsible for both the New Guinea and Solomon Islands campaigns . The Japanese 18th Army , under Lieutenant General Hatazō Adachi ,

702-454: A crucial strategic victory by turning the Japanese landing force back, thereby removing the threat to Port Moresby, at least for the time being. After this failure, the Japanese decided on a longer term, two-pronged assault for their next attempt on Port Moresby. Forward positions would first be established at Milne Bay , located in the forked eastern end of the Papuan peninsula, and at Buna ,

819-461: A date which later became Australia's national day . Most early settlers were convicts , transported for petty crimes and assigned as labourers or servants to "free settlers" (willing immigrants). Once emancipated , convicts tended to integrate into colonial society. Convict rebellions and uprisings were suppressed under martial law, which lasted for two years following the 1808 Rum Rebellion , Australia's only successful coup d'état . During

936-442: A defence in depth. Also, Yamamoto accepted at face value his fliers' over-optimistic reports of damage: they reported a score of one cruiser, two destroyers and 25 transports, as well as 175 Allied planes, a figure that should certainly have aroused some skepticism. Actual Allied losses amounted to one destroyer, one oiler, one corvette, two cargo ships and approximately 25 aircraft. These meager results were not commensurate with either

1053-610: A little more than halfway between Milne Bay and the Buna–Gona area. Wau is a village in the interior of the Papuan Peninsula , approximately 50 kilometres (30 mi) southwest of Salamaua. An airfield had been built there during an area gold rush in the 1920s and 1930s. This airfield was of great value to the Australians during the fighting for northeast Papua. Once the Japanese had decided to give up on Guadalcanal ,

1170-656: A naval engagement appeared to be brewing in the Coral Sea , the Japanese Moresby transports immediately veered back to the north, in order to avoid combat. The resulting Battle of the Coral Sea inflicted significant aircraft losses on the Fourth Fleet , Shōhō was sunk, and Shōkaku was damaged. Air groups from the two carriers, including the relatively undamaged Zuikaku , suffered such sizable losses, it

1287-461: A result some claim that 97% of Japanese deaths in this campaign were from non-combat causes. According to John Laffin , the campaign "was arguably the most arduous fought by any Allied troops during World War II ." The struggle for New Guinea began with the capture by the Japanese of the city of Rabaul at the northeastern tip of New Britain in January 1942. Rabaul overlooks Simpson Harbour ,

1404-619: A seaplane base at Tulagi in the lower Solomons, one to establish a seaplane base in the Louisiade Archipelago off the eastern tip of New Guinea, one of transports to land troops near Port Moresby, one with a light carrier to cover the landing, and one with two fleet carriers to sink the Allied forces sent in response. In the resulting 4–8 May 1942 Battle of the Coral Sea , the Allies suffered higher losses in ships but achieved

1521-581: A settlement was established in Van Diemen's Land (present-day Tasmania ), and in 1813, Gregory Blaxland , William Lawson and William Wentworth crossed the Blue Mountains west of Sydney, opening the interior to European settlement. The British claim extended to the whole Australian continent in 1827 when Major Edmund Lockyer established a settlement on King George Sound (modern-day Albany ). The Swan River Colony (present-day Perth )

1638-562: A short distance off the north-east coast and extends for more than 2,000 km (1,200 mi). Mount Augustus , claimed to be the world's largest monolith, is located in Western Australia. At 2,228 m (7,310 ft), Mount Kosciuszko is the highest mountain on the Australian mainland. Even taller are Mawson Peak , at 2,745 m (9,006 ft), on the remote Australian external territory of Heard Island , and, in

1755-423: A village on the northeast coast of Papua about halfway between Huon Gulf and Milne Bay. Simultaneous operations from these two locations, one amphibious and one overland, would converge on the target city. "[T]he Owen Stanley Range is a jagged, precipitous obstacle covered with tropical rainforest up to the pass at 6500-foot elevation, and with moss like a thick wet sponge up to the highest peaks, 13,000 feet above

1872-411: A wide variety of landscapes, with tropical rainforests in the north-east, mountain ranges in the south-east, south-west and east, and desert in the centre. The desert or semi-arid land commonly known as the outback makes up by far the largest portion of land. Australia is the driest inhabited continent; its annual rainfall averaged over continental area is less than 500 mm. The population density

1989-436: Is 3.4 inhabitants per square kilometre, although the large majority of the population lives along the temperate south-eastern coastline. The population density exceeds 19,500 inhabitants per square kilometre in central Melbourne. In 2021 Australia had 10% of the global permanent meadows and pastureland. Forest cover is around 17% of Australia's total land area. The Great Barrier Reef , the world's largest coral reef, lies

2106-413: Is a constitutional monarchy , a parliamentary democracy and a federation . The country has maintained its mostly unchanged constitution alongside a stable liberal democratic political system since Federation in 1901. It is one of the world's oldest federations, in which power is divided between the federal and state governments. The Australian system of government combines elements derived from

It is a member of international groups including the United Nations; the G20 ; the OECD ; the World Trade Organization ; Asia-Pacific Economic Cooperation ; the Pacific Islands Forum ; the Pacific Community ; the Commonwealth of Nations ; and the defence and security organisations ANZUS , AUKUS , and the Five Eyes . It

2340-753: Is also a major non-NATO ally of the United States. The name Australia (pronounced / ə ˈ s t r eɪ l i ə / in Australian English ) is derived from the Latin Terra Australis ( ' southern land ' ), a name used for a hypothetical continent in the Southern Hemisphere since ancient times. Several 16th-century cartographers used the word Australia on maps, but not to identify modern Australia. When Europeans began visiting and mapping Australia in

Operation Mo The plan was developed by the Imperial Japanese Navy and supported by Admiral Isoroku Yamamoto , the commander-in-chief of the Combined Fleet , but the operation was eventually abandoned. When

2691-629: Is one of only two pristine Archaean 3.6–2.7 Ga (billion years ago) crusts identified on the Earth. Having been part of all major supercontinents , the Australian continent began to form after the breakup of Gondwana in the Permian , with the separation of the continental landmass from the African continent and Indian subcontinent. It separated from Antarctica over a prolonged period beginning in

2808-617: Is uncertain how many waves of immigration may have contributed to these ancestors of modern Aboriginal Australians. The Madjedbebe rock shelter in Arnhem Land is possibly the oldest site showing the presence of humans in Australia. The oldest human remains found are the Lake Mungo remains , which have been dated to around 41,000 years ago. Aboriginal Australian culture is one of the oldest continuous cultures on Earth. At

2925-411: Is unique. About 85% of flowering plants, 84% of mammals, more than 45% of birds , and 89% of in-shore, temperate-zone fish are endemic . Australia has at least 755 species of reptile, more than any other country in the world. Besides Antarctica, Australia is the only continent that developed without feline species. Feral cats may have been introduced in the 17th century by Dutch shipwrecks, and later in

3042-661: The Admiralty agreed that the continent should be known officially by that name. The first official published use of the new name came with the publication in 1830 of The Australia Directory by the Hydrographic Office . Colloquial names for Australia include " Oz ", " Straya " and " Down Under ". Other epithets include "the Great Southern Land", "the Lucky Country" (from the 1964 book of

3159-500: The Australia Acts of 1986. Australia is a federal parliamentary democracy and constitutional monarchy comprising six states and ten territories . Its population of more than 28 million is highly urbanised and heavily concentrated on the eastern seaboard. Canberra is the nation's capital, while its most populous cities are Sydney and Melbourne , both with a population of more than 5 million. Australia's culture

3276-557: The Battle of Milne Bay became an infantry struggle in the sopping jungle carried on mostly at night under pouring rain. The Aussies were fighting mad, for they had found some of their captured fellows tied to trees and bayoneted to death, surmounted by the placard, 'It took them a long time to die'." – Samuel Eliot Morison, Breaking the Bismarcks Barrier , p. 38 While it was beyond MacArthur's capabilities to deny Buna to

3393-468: The Bismarck Sea , they might make it to Lae with an acceptable level of loss, i.e., at worst half the task force would be sunk en route. It is indicative of the extent to which Japanese ambitions had fallen at this point in the war that a 50% loss of ground troops aboard ship was considered acceptable. Three factors conspired to create disaster for the Japanese. First, they had woefully underestimated

3510-595: The Gulf Country —with their tropical climate—include forest, woodland, wetland, grassland, rainforest and desert. At the north-west corner of the continent are the sandstone cliffs and gorges of The Kimberley , and below that the Pilbara . The Victoria Plains tropical savanna lies south of the Kimberley and Arnhem Land savannas, forming a transition between the coastal savannas and the interior deserts. At

3627-551: The Indian Ocean Dipole and the El Niño–Southern Oscillation , which is correlated with periodic drought , and the seasonal tropical low-pressure system that produces cyclones in northern Australia. These factors cause rainfall to vary markedly from year to year. Much of the northern part of the country has a tropical, predominantly summer-rainfall ( monsoon ). The south-west corner of the country has

The nation's trade relations also became increasingly oriented towards East Asia in the 21st century, with China becoming the nation's largest trading partner by a large margin. In 2020, during the COVID-19 pandemic , several of Australia's largest cities were locked down for extended periods and free movement across the national and state borders was restricted in an attempt to slow

3861-664: The Menzies Government to ban the Communist Party of Australia , and a bitter split in the Labor Party in 1955. As a result of a 1967 referendum , the federal government gained the power to legislate with regard to Indigenous Australians, and Indigenous Australians were fully included in the census . Pre-colonial land interests (referred to as native title in Australia) was recognised in law for

3978-958: The Netherlands East Indies ) beginning on 29 March. During the second phase, lasting from late 1942 until the Japanese surrender, the Allies —consisting primarily of Australian forces—cleared the Japanese first from Papua, then New Guinea, and finally from the Dutch colony. The campaign resulted in a crushing defeat and heavy losses for the Empire of Japan. As in most Pacific War campaigns, disease and starvation claimed more Japanese lives than enemy action. Most Japanese troops never even came into contact with Allied forces and were instead simply cut off and subjected to an effective blockade by Allied naval forces. Garrisons were effectively besieged and denied shipments of food and medical supplies, and as

4095-532: The Permian and continuing through to the Cretaceous . When the last glacial period ended in about 10,000 BC, rising sea levels formed Bass Strait , separating Tasmania from the mainland. Then between about 8,000 and 6,500 BC, the lowlands in the north were flooded by the sea, separating New Guinea, the Aru Islands , and the mainland of Australia. The Australian continent is moving toward Eurasia at

4212-679: The Quebec Conference in August 1943, the leaders of the Allied nations agreed to this change in strategy focusing on neutralizing Rabaul rather than capturing it. Despite the disaster of the Bismarck Sea, the Japanese could not give up on recapturing Wau, and they kept significant resources in the territory of Papua, on north shore of the eastern end New Guinea. The Australians were there to restrict Japanese build up there, as any base construction or build up there would threaten

4329-634: The Territory of Papua and New Guinea in 1949 and gained independence from Australia in 1975. In 1914, Australia joined the Allies in fighting the First World War, and took part in many of the major battles fought on the Western Front . Of about 416,000 who served, about 60,000 were killed and another 152,000 were wounded. Many Australians regard the defeat of the Australian and New Zealand Army Corps (ANZAC) at Gallipoli in 1915 as

4446-528: The Torres Strait Islands . The Dutch charted the whole of the western and northern coastlines and named the island continent " New Holland " during the 17th century, and although no attempt at settlement was made, a number of shipwrecks left men either stranded or, as in the case of the Batavia in 1629, marooned for mutiny and murder, thus becoming the first Europeans to permanently inhabit

4563-696: The bombing of Darwin and other Japanese attacks on Australian soil , led to a widespread belief in Australia that a Japanese invasion was imminent , and a shift from the United Kingdom to the United States as Australia's principal ally and security partner. Since 1951, Australia has been allied with the United States under the ANZUS treaty. In the decades following World War II, Australia enjoyed significant increases in living standards, leisure time and suburban development. Governments encouraged

4680-426: The emu and the kookaburra . Australia is home to many dangerous animals including some of the most venomous snakes in the world. The dingo was introduced by Austronesian people who traded with Indigenous Australians around 3000 BCE . Many animal and plant species became extinct soon after first human settlement, including the Australian megafauna ; others have disappeared since European settlement, among them

4797-595: The governor-general at the federal level and by the governors at the state level, who by section 63 of the Constitution and convention act on the advice of their ministers. Thus, in practice the governor-general acts as a legal figurehead for the actions of the prime minister and the Cabinet. The governor-general may in some situations exercise reserve powers : powers exercisable in the absence or contrary to ministerial advice. When these powers may be exercised

4914-409: The last glacial period . By the time of British settlement, Aboriginal Australians spoke 250 distinct languages and had the oldest living culture in the world. Australia's written history commenced with Dutch exploration of most of the coastline in the 17th-century. British colonisation began in 1788 with the establishment of the penal colony of New South Wales . By the mid-19th century, most of

5031-661: The "baptism of fire" that forged the new nation's identity . The beginning of the campaign is commemorated annually on Anzac Day , a date which rivals Australia Day as the nation's most important. From 1939 to 1945, Australia joined the Allies in fighting the Second World War. Australia's armed forces fought in the Pacific , European and Mediterranean and Middle East theatres .

Australia has 34,218 km (21,262 mi) of coastline (excluding all offshore islands), and claims an extensive exclusive economic zone of 8,148,250 square kilometres (3,146,060 sq mi). This exclusive economic zone does not include the Australian Antarctic Territory . Mainland Australia lies between latitudes 9° and 44° south , and longitudes 112° and 154° east . Australia's size gives it

5265-443: The 17th century, the name Terra Australis was applied to the new territories. Until the early 19th century, Australia was best known as New Holland , a name first applied by the Dutch explorer Abel Tasman in 1644 (as Nieuw-Holland ) and subsequently anglicised. Terra Australis still saw occasional usage, such as in scientific texts. The name Australia was popularised by the explorer Matthew Flinders , who said it

5382-428: The 18th century by European settlers. They are now considered a major factor in the decline and extinction of many vulnerable and endangered native species. Seafaring immigrants from Asia are believed to have brought the dingo to Australia sometime after the end of the last ice age—perhaps 4000 years ago—and Aboriginal people helped disperse them across the continent as pets, contributing to the demise of thylacines on

5499-543: The 2018 Environmental Performance Index . There are more than 1,800 animals and plants on Australia's threatened species list, including more than 500 animals. Paleontologists discovered a fossil site of a prehistoric rainforest in McGraths Flat , in South Australia, that presents evidence that this now arid desert and dry shrubland / grassland was once home to an abundance of life. Australia

5616-656: The Australian Antarctic Territory, Mount McClintock and Mount Menzies , at 3,492 m (11,457 ft) and 3,355 m (11,007 ft) respectively. Eastern Australia is marked by the Great Dividing Range , which runs parallel to the coast of Queensland, New South Wales and much of Victoria. The name is not strictly accurate, because parts of the range consist of low hills, and the highlands are typically no more than 1,600 m (5,200 ft) in height. The coastal uplands and

5733-558: The Australian mainland. The first ship and crew to chart the Australian coast and meet with Aboriginal people was the Duyfken , captained by Dutch navigator Willem Janszoon . He sighted the coast of Cape York Peninsula in early 1606, and made landfall on 26 February 1606 at the Pennefather River near the modern town of Weipa on Cape York. Later that year, Spanish explorer Luís Vaz de Torres sailed through and navigated

5850-508: The Composite Anti-Aircraft Defences played a crucial role in protecting Port Moresby, which suffered 78 air raids by 17 August 1942. A gradual improvement the numbers and skill of anti-aircraft gunners forced the Japanese bombers up to higher altitude, where they were less accurate, and then, in August, to raiding by night. Although RAAF PBY Catalinas and Lockheed Hudsons were based at Port Moresby, because of

5967-540: The IJN was amassing a large force at Truk, and planned to occupy Tulagi also. MacArthur got an Australian reconnaissance plane to "discover" the Port Moresby invasion force on 5 May, leading to the Battle of the Coral Sea (see Central Bureau ). The Tulagi assault force, led by Rear Admiral Kiyohide Shima , was composed of the following units: The Port Moresby occupation force, led by Rear Admiral Sadamichi Kajioka ,

6084-633: The Japanese Army-Navy landing on 7 May. The Tulagi assault force began their landings on Tulagi on 3 May. On 4 May 1942, troopships bearing the South Seas Detachment set sail southward from Rabaul for Port Moresby. This same day US aircraft from Yorktown attacked the Tulagi assault force, inflicting heavy damage, but were unsuccessful in preventing the occupation of Tulagi, Gavutu, and Tanambogo islands. Three days later, as

6201-406: The Japanese Navy was planning the New Guinea Campaign ( air strikes against Lae and Salamaua , disembarkation in Huon Gulf , New Britain ( Rabaul ), New Ireland ( Kavieng ), Finch Harbor (also called Finschhafen), and the capture of Morobe and Buna ), strategists envisioned those territories as support points to implement the capture of Port Moresby . The implementation of these operations

6318-522: The Japanese air attacks, long-range bombers like B-17s , B-25s , and B-26s could not be safely based there and were instead staged through from bases in Australia. This resulted in considerable fatigue for the air crews. Due to USAAF doctrine and a lack of long-range escorts, long-range bomber raids on targets like Rabaul went in unescorted and suffered heavy losses, prompting severe criticism of Lieutenant General George Brett by war correspondents for misusing his forces. But fighters did provide cover for

6435-410: The Japanese completed their evacuation of Guadalcanal . General Imamura and his naval counterpart at Rabaul, Admiral Jinichi Kusaka , commander Southeast Area Fleet , resolved to reinforce their ground forces at Lae for one final all-out attempt against Wau. If the transports succeeded in staying behind a weather front and were protected the whole way by fighters from the various airfields surrounding

6552-414: The Japanese had reached the village of Ioribaiwa, just 30 kilometres (20 mi) from the Allied airdrome at Port Moresby. The Australians held firm and began their counterdrive on 26 September. According to historian Samuel Eliot Morison , "...the Japanese retreat down the Kokoda Track had turned into a rout. Thousands perished from starvation and disease; the commanding general, Horii , was drowned." Thus

6669-552: The Japanese position. Beleaguered, the survivors of the Japanese garrison were evacuated by submarine on the night of 26 October. The Allies proceeded to turn the island into an air base. "In the swamp country which surrounded the area were large crocodiles ... Incidence of malaria was almost one hundred per cent. At Sanananda the swamp and jungle were typhus-ridden ... crawling roots reached out into stagnant pools infested with mosquitoes and numerous crawling insects ... every foxhole filled with water. Thompson sub machine-guns jammed with

6786-403: The Japanese). The Japanese occupied the village with an initial force of 1,500 on 21 July 1942 and by 22 August had 11,430 men under arms at Buna. The Japanese objective was to seize Port Moresby by an overland advance from the north coast, following the Kokoda Track over the mountains of the Owen Stanley Range, as part of a strategy to isolate Australia from the United States. By 17 September

6903-427: The Japanese, the same could not be said of Milne Bay, which was easily accessible by Allied naval forces. In early June, US Army engineers, Australian infantry and an anti-aircraft battery were landed at Gili Gili , and work was begun on an airfield. By 22 August, about 8,500 Australians and 1,300 Americans were on site. The Japanese arrived and the 25 August – 7 September Battle of Milne Bay was underway. Morison sums up

7020-445: The Lae-Salamaua area. Opposing these forces were the Australian 2/5th , 2/6th and 2/7th Battalions along with Lieutenant Colonel Norman Fleay's Kanga Force . The Australians decisively turned back the Japanese assault in the ensuing 29–31 January 1943 Battle of Wau . "Within a few days, the enemy was retreating from the Wau Valley, where he had suffered a serious defeat, harassed all the way back to Mubo ..." About one week later,

7137-442: The P-39s and P-40s—giving the Japanese an altitude advantage in air combat. The cost to the Allied fighters was high. Before June, between 20 and 25 P-39s had been lost in air combat, while three more had been destroyed on the ground, and eight had been destroyed in landings by accident. The following month at least 20 fighters were lost in combat, while eight were destroyed in July. The Australian and American anti-aircraft gunners of

7254-401: The capture of Port Moresby loomed even larger in their strategic thinking. Taking the airfield at Wau was a crucial step in this process, and to this end, the 51st Division was transferred from Indochina and placed under Imamura's Eighth Area Army at Rabaul; one regiment arrived at Lae in early January 1943. In addition, about 5,400 survivors of the Japanese defeat at Buna-Gona were moved into

Volcanism also occurs in

7488-420: The colonies was achieved after a decade of planning, constitutional conventions and referendums , resulting in the establishment of the Commonwealth of Australia as a nation under the new Australian Constitution . After the 1907 Imperial Conference , Australia and several other self-governing British settler colonies were given the status of self-governing dominions within the British Empire. Australia

7605-457: The command of Major General George Alan Vasey , along with the revitalized US 32nd Division, restarted the Allied offensive. Gona fell to the Australians on 9 December 1942, Buna to the US 32nd on 2 January 1943, and Sanananda , located between the two larger villages, fell to the Australians on 22 January. Operation Lilliput (18 December 1942 – June 1943) was an ongoing resupply operation ferrying troops and supplies from Milne Bay to Oro Bay ,

7722-402: The continent had been explored by European settlers and five additional self-governing British colonies were established, each gaining responsible government by 1890. The colonies federated in 1901, forming the Commonwealth of Australia. This continued a process of increasing autonomy from the United Kingdom, highlighted by the Statute of Westminster Adoption Act 1942 , and culminating in

7839-475: The continent. In 1770, Captain James Cook sailed along and mapped the east coast, which he named " New South Wales " and claimed for Great Britain. Following the loss of its American colonies in 1783, the British Government sent a fleet of ships, the First Fleet , under the command of Captain Arthur Phillip , to establish a new penal colony in New South Wales . A camp was set up and the Union Flag raised at Sydney Cove , Port Jackson , on 26 January 1788,

7956-478: The convict system culminated in its abolition in the eastern colonies by the 1850s. Initially a free colony, Western Australia practised penal transportation from 1850 to 1868. The six colonies individually gained responsible government between 1855 and 1890, thus becoming elective democracies managing most of their own affairs while remaining part of the British Empire . The Colonial Office in London retained control of some matters, notably foreign affairs. In

8073-455: The defenders, could not succeed. The D'Entrecasteaux Islands lie directly off the northeast coast of the lower portion of the Papuan peninsula. The westernmost island of this group, Goodenough , had been occupied in August 1942 by 353 stranded troops from bombed Japanese landing craft. The destroyer Yayoi , sent to recover these men, was bombed and sunk on 11 September. A force of 800 Australian troops landed on 22 October on either side of

Although most of Australia is semi-arid or desert, the continent includes a diverse range of habitats from alpine heaths to tropical rainforests . Fungi typify that diversity—an estimated 250,000 species—of which only 5% have been described—occur in Australia. Because of the continent's great age, extremely variable weather patterns, and long-term geographic isolation, much of Australia's biota

Japanese naval intelligence also suspected the presence of the American aircraft carrier USS  Yorktown in Coral Sea waters during this period. A Japanese message on 9 April 1942 indicated that the "RZP Campaign" against Port Moresby was to be an invasion, not an air raid, and which would isolate Australia from America. USN codebreaker Rudy Fabian at FRUMEL briefed MacArthur who

For this, he ordered the air arm of Vice Admiral Jisaburō Ozawa 's Third Fleet carriers to reinforce the Eleventh Air Fleet at Rabaul. To demonstrate the seriousness of the effort to the Supreme War Council, multiple shifts of high-ranking personnel were also effected: both Yamamoto and Ozawa moved their headquarters to Rabaul; and Eighth Fleet commander Vice Admiral Gunichi Mikawa as well as General Imamura's chief of staff were sent to Tokyo with advice and explanations for

8541-772: The first time when the High Court of Australia held in Mabo v Queensland (No 2) that Australia was neither terra nullius ( ' land belonging to no one ' ) or "desert and uncultivated land" at the time of European settlement. Following the abolition of the last vestiges of the White Australia policy in 1973, Australia's demography and culture transformed as a result of a large and ongoing wave of non-European immigration, mostly from Asia. The late 20th century also saw an increasing focus on foreign policy ties with other Pacific Rim nations. The Australia Acts severed

8658-581: The gritty mud and were unreliable in the humid atmosphere ... " – John Vader, New Guinea: The Tide Is Stemmed , pp. 102–103 The Japanese drive to conquer all of New Guinea had been decisively stopped. MacArthur was determined to liberate the island as a stepping-stone to the reconquest of the Philippines. MacArthur's rollback began on 16 November. The inexperience of the US 32nd Infantry Division , just out of training camp and unschooled in jungle warfare ,

8775-412: The heart of the country are the uplands of central Australia . Prominent features of the centre and south include Uluru (also known as Ayers Rock), the famous sandstone monolith, and the inland Simpson , Tirari and Sturt Stony , Gibson , Great Sandy, Tanami , and Great Victoria deserts, with the famous Nullarbor Plain on the southern coast. The Western Australian mulga shrublands lie between

8892-479: The interior deserts and Mediterranean-climate Southwest Australia . Lying on the Indo-Australian Plate , the mainland of Australia is the lowest and most primordial landmass on Earth with a relatively stable geological history. The landmass includes virtually all known rock types and from all geological time periods spanning more than 3.8 billion years of the Earth's history. The Pilbara Craton

9009-417: The island of New Guinea (considered geologically as part of the Australian continent), and in the Australian external territory of Heard Island and McDonald Islands . Seismic activity in the Australian mainland and Tasmania is also low, with the greatest number of fatalities having occurred in the 1989 Newcastle earthquake . The climate of Australia is significantly influenced by ocean currents, including

9126-428: The largest raid of all, 188 aircraft struck Milne Bay on 14 April. I-Go demonstrated that the Japanese command was not learning the lessons of air power that the Allies were. The Allied reduction of Rabaul was only made possible by relentless air strikes that took place day after day, but Yamamoto thought the damage inflicted by a few attacks of large formations would derail Allied plans long enough for Japan to prepare

9243-555: The location for the future federal capital of Canberra . While it was being constructed, Melbourne served as the temporary capital from 1901 to 1927. The Northern Territory was transferred from the control of South Australia to the Commonwealth in 1911. Australia became the colonial ruler of the Territory of Papua (which had initially been annexed by Queensland in 1883) in 1902 and of the Territory of New Guinea (formerly German New Guinea ) in 1920. The two were unified as

9360-448: The mainland. Australia is also one of 17 megadiverse countries. Australian forests are mostly made up of evergreen species, particularly eucalyptus trees in the less arid regions; wattles replace them as the dominant species in drier regions and deserts. Among well-known Australian animals are the monotremes (the platypus and echidna ); a host of marsupials , including the kangaroo , koala , and wombat , and birds such as

9477-474: The mid-19th century, explorers such as Burke and Wills charted Australia's interior. A series of gold rushes beginning in the early 1850s led to an influx of new migrants from China , North America and continental Europe, as well as outbreaks of bushranging and civil unrest; the latter peaked in 1854 when Ballarat miners launched the Eureka Rebellion against gold license fees. The 1860s saw

9594-402: The newly devised practice of skip bombing . About 6,900 troops aboard eight transports, escorted by eight destroyers, departed Rabaul at midnight 28 February under the command of Rear Admiral Masatomi Kimura . Through the afternoon of 1 March, the overcast weather held at which point everything began to go wrong for the Japanese. The weather changed direction and Kimura's slow-moving task force

9711-602: The next two decades, social and economic reforms, together with the establishment of a Legislative Council and Supreme Court , saw the penal colony transition to a civil society. The indigenous population declined for 150 years following European settlement, mainly due to infectious disease. British colonial authorities did not sign any treaties with Aboriginal groups . As settlement expanded, tens of thousands of Indigenous people and thousands of settlers were killed in frontier conflicts while settlers dispossessed surviving Indigenous peoples of most of their land. In 1803,

9828-723: The northeast coast of Papua, are the Huon Gulf and the Huon Peninsula . The Japanese entered Lae and Salamaua , two towns on Huon Gulf, on 8 March 1942, unopposed. MacArthur would have liked to deny this area to the Japanese, but he had neither sufficient air nor naval forces to undertake a counterlanding. The Japanese at Rabaul and other bases on New Britain would have easily overwhelmed any such effort (by mid-September, MacArthur's entire naval force under Vice Admiral Arthur S. Carpender consisted of 5 cruisers, 8 destroyers, 20 submarines, and 7 small craft). The only Allied response

9945-428: The political systems of the United Kingdom (a fused executive , constitutional monarchy and strong party discipline ) and the United States ( federalism , a written constitution and strong bicameralism with an elected upper house), resulting in a distinct hybrid. Federal government power is partially separated between three groups: Charles III reigns as King of Australia and is represented in Australia by

10062-594: The protection of threatened species. Numerous protected areas have been created under the National Strategy for the Conservation of Australia's Biological Diversity to protect and preserve unique ecosystems; 65 wetlands are listed under the Ramsar Convention , and 16 natural World Heritage Sites have been established. Australia was ranked 21st out of 178 countries in the world on

10179-480: The rate of 6 to 7 centimetres a year. The Australian mainland's continental crust , excluding the thinned margins, has an average thickness of 38   km, with a range in thickness from 24 km to 59 km. Australia's geology can be divided into several main sections, showcasing that the continent grew from west to east: the Archaean cratonic shields found mostly in the west, Proterozoic fold belts in

10296-545: The remaining constitutional ties between Australia and the United Kingdom while maintaining the monarch in her independent capacity as Queen of Australia . In a 1999 constitutional referendum , 55% of voters rejected abolishing the monarchy and becoming a republic. Following the September 11 attacks on the United States, Australia joined the United States in fighting the Afghanistan War from 2001 to 2021 and

10413-495: The resources expended or the expectations that had been promoted. In order to reduce and capture the vast Japanese naval and air facilities at Rabaul, two major moves were planned for the end of June: Eventually, the Joint Chiefs of Staff realized that a landing and siege of "Fortress Rabaul" would be far too costly and that the Allies' ultimate strategic purposes could be achieved by simply neutralizing and bypassing it. At

10530-419: The resources of their reefs and seas. Agriculture also developed on some islands and villages appeared by the 1300s. By the mid-18th century in northern Australia, contact, trade and cross-cultural engagement had been established between local Aboriginal groups and Makassan trepangers , visiting from present-day Indonesia. The Dutch are the first Europeans that recorded sighting and making landfall on

10647-540: The respective General Staffs (Vice Admiral Tomoshige Samejima replaced Mikawa as Eighth Fleet commander). Operation I-Go was to be carried out in two phases, one against the lower Solomons and one against Papua. The first strike, on 7 April, was against Allied shipping in the waters between Guadalcanal and Tulagi . At 177 planes, this was the largest Japanese air attack since Pearl Harbor . Yamamoto then turned his attention to New Guinea: 94 planes struck Oro Bay on 11 April; 174 planes hit Port Moresby on 12 April; and in

10764-544: The results this way: ...the enemy had shot his bolt; he never showed up again in these waters. The Battle for Milne Bay was a small one as World War II engagements went, but very important. Except for the initial assault on Wake Island, this was the first time that a Japanese amphibious operation had been thrown for a loss ... Furthermore, the Milne Bay affair demonstrated once again that an amphibious assault without air protection, and with an assault force inferior to that of

10881-491: The rise of blackbirding , where South Sea Islanders were coerced or abducted into indentured labour, mainly by Queensland colonists. From 1886, Australian colonial governments began removing many Aboriginal children from their families and communities, justified on the grounds of child protection and forced assimilation policies. The Second Boer War (1899–1902) marked the largest overseas deployment of Australia's colonial forces . On 1 January 1901, federation of

10998-549: The same name ), "the Sunburnt Country", and "the Wide Brown Land". The latter two both derive from Dorothea Mackellar 's 1908 poem " My Country ". Indigenous Australians comprise two broad groups: Human habitation of the Australian continent is estimated to have begun 50,000 to 65,000 years ago, with the migration of people by land bridges and short sea crossings from what is now Southeast Asia. It

The Kokoda Trail [was] suitable for splay-toed Papuan aborigines but a torture to modern soldiers carrying heavy equipment..." – Samuel Eliot Morison, Breaking the Bismarcks Barrier , p. 34 Buna was easily taken as the Allies had no military presence there (MacArthur wisely chose not to attempt an occupation by paratroopers since any such force would have been easily wiped out by

11232-415: The southern shore of New Guinea and across the sea to the northern shores of Australia. Australia Australia , officially the Commonwealth of Australia , is a country comprising the mainland of the Australian continent , the island of Tasmania and numerous smaller islands . Australia has a total area of 7,688,287 km (2,968,464 sq mi), making it the sixth-largest country in

11349-685: The spread of the SARS-CoV-2 virus . Surrounded by the Indian and Pacific oceans, Australia is separated from Asia by the Arafura and Timor seas, with the Coral Sea lying off the Queensland coast, and the Tasman Sea lying between Australia and New Zealand. The world's smallest continent and sixth-largest country by total area , Australia—owing to its size and isolation—is often dubbed

11466-578: The strength of the Allied air forces. Second, the Allies had become convinced that the Japanese were preparing a major seaborne reinforcement and so had stepped up their air searches. Most important of all, the bombers of MacArthur's air forces, under the command of Lieutenant General George C. Kenney , had been modified to enable new offensive tactics. The noses of several Douglas A-20 Havoc light bombers had been refitted with eight 50-caliber machine guns for strafing slow-moving ships. In addition, their bomb bays were filled with 500-pound bombs to be used in

11583-406: The thylacine. Many of Australia's ecoregions, and the species within those regions, are threatened by human activities and introduced animal, chromistan , fungal and plant species. All these factors have led to Australia's having the highest mammal extinction rate of any country in the world. The federal Environment Protection and Biodiversity Conservation Act 1999 is the legal framework for

11700-1029: The time of first European contact, Aboriginal Australians belonged to wide range of societies, with diverse economies spread across at least 250 different language groups . Estimates of the Aboriginal population before British settlement range from 300,000 to 3 million. Aboriginal Australians cultures were (and remain) deeply connected with the land and the environment, with stories of The Dreaming maintained through oral tradition , songs , dance and paintings. Certain groups engaged in fire-stick farming , fish farming , and built semi-permanent shelters . These practices have variously been characterised as " hunter-gatherer ", " agricultural ", "natural cultivation" and "intensification". Torres Strait Islander people first settled their islands at least 2,500 years ago. Culturally and linguistically distinct from mainland Aboriginal peoples, they were seafarers and obtained their livelihood from seasonal horticulture and

11817-654: The transports and for bombers when their targets were within range. Aircraft based at Port Moresby and Milne Bay fought to prevent the Japanese from basing aircraft at Buna, and attempted to prevent the Japanese reinforcement of the Buna area. As the Japanese ground forces pressed toward Port Moresby, the Allied Air Forces struck supply points along the Kokoda Track. Japanese makeshift bridges were attacked by P-40s with 500 lb (230 kg) bombs. "Thenceforth,

11934-518: The world and the largest country by area in Oceania . It is the world's oldest, flattest, and driest inhabited continent, with some of the least fertile soils. It is a megadiverse country , and its size gives it a wide variety of landscapes and climates including deserts in the interior and tropical rainforests along the coast . The ancestors of Aboriginal Australians began arriving from south-east Asia 50,000 to 65,000 years ago, during

12051-402: Was "incredulous" as he expected the target would be New Caledonia, so Fabian explained the (JN-25) code-breaking process and showed him the Japanese commander’s intercepted message with the objectives to restrict enemy fleet movements and attack the north coast of Australia. So a transport due to leave the next day for New Caledonia was sent to Port Moresby. On 23 April Fabian showed MacArthur that

12168-531: Was "more agreeable to the ear, and an assimilation to the names of the other great portions of the Earth". The first time that Australia appears to have been officially used was in April 1817, when Governor Lachlan Macquarie acknowledged the receipt of Flinders' charts of Australia from Lord Bathurst . In December 1817, Macquarie recommended to the Colonial Office that it be formally adopted. In 1824,

12285-615: Was Australia's warmest recorded year, and the 2019–2020 bushfire season was the country's worst on record . Australia's greenhouse gas emissions per capita are among the highest in the world. Water restrictions are frequently in place in many regions and cities of Australia in response to chronic shortages due to urban population increases and localised drought. Throughout much of the continent, major flooding regularly follows extended periods of drought, flushing out inland river systems, overflowing dams and inundating large inland flood plains, as occurred throughout Eastern Australia in

12402-467: Was a bombing raid of Lae and Salamaua by aircraft flying over the Owen Stanley Range from the carriers USS  Lexington and USS  Yorktown , leading the Japanese to reinforce these sites. Operation Mo was the designation given by the Japanese to their initial plan to take possession of Port Moresby. Their operation plan decreed a five-pronged attack: one task force to establish

12519-731: Was assigned to the Japanese Naval task force led by Admiral Chūichi Nagumo , after completing the Java campaign. Another important step was the occupation of Christmas Island to the south of Java. The Japanese Navy General Staff had been considering Operation Mo since 1938, as a step in the consolidation of the Southern Seas areas in the Greater East Asia Co-Prosperity Sphere ( 大東亜共栄圏 , Dai-tō-a Kyōeiken ) . The Directive of Operation Mo

12636-716: Was composed of the following units: Supporting these operations and intercepting any Allied interference, Rear Admiral Aritomo Goto commanded: During the course of operation, Yamamoto sent the following heavy support force from Truk , led by Rear Admiral Chuichi Hara : Supporting this force was the 25th Air Fleet, (Yokohama Air Corps) led by Rear Admiral Sadayoshi Yamada , based in Rabaul, Lae , Salamaua , Buna and Deboyne Islands , composed of 60 Mitsubishi A6M "Zero" fighters, 48 Mitsubishi G3M "Nell" and 26 Aichi E13A "Jake" and Mitsubishi F1M "Pete" reconnaissance seaplanes. This unit bombed Port Moresby on 5–6 May, ahead of

12753-523: Was conceived in 1938, but with no specific time for its execution, pending earlier successes in the southern area during the first and second phases of the conquest. In April 1942, the operation was organized into four large actions and was approved by the Army and Navy General Staffs: Japanese planners took into account an Allied response to the operation by detaching one task force to the west of parallel between of Rennel and Deboyne Islands and another to

12870-492: Was determined to hold it. MacArthur was further determined to conquer all of New Guinea in his progress toward the eventual recapture of the Philippines. General Headquarters South West Pacific Area Operational Instruction No.7 of 25 May 1942, issued by MacArthur, placed all Australian and US Army, Air Force and Navy Forces in the Port Moresby Area under the control of New Guinea Force . Due north of Port Moresby, on

12987-413: Was established in 1829, evolving into the largest Australian colony by area, Western Australia . In accordance with population growth, separate colonies were carved from New South Wales: Tasmania in 1825, South Australia in 1836, New Zealand in 1841, Victoria in 1851, and Queensland in 1859. South Australia was founded as a free colony—it never accepted transported convicts. Growing opposition to

13104-554: Was nearly disastrous. Instances were noted of officers completely out of their depth, of men eating meals when they should have been on the firing line, even of cowardice. MacArthur relieved the division commander and on 30 November instructed Lieutenant General Robert L. Eichelberger , commander of the US I Corps , to go to the front personally with the charge "to remove all officers who won't fight ... if necessary, put sergeants in charge of battalions ... I want you to take Buna, or not come back alive." The Australian 7th Division under

13221-484: Was necessary they return to Japan to re-equip and train. The Japanese abandoned their plans to land the South Seas Detachment directly at Port Moresby from the sea. The Japanese Army was making new preparations for combat when, on 11 July, High Command ordered the suspension of Operation FS the projected actions against New Caledonia , Fiji , and Samoa , after the remaining Japanese carrier strength

13338-579: Was one of the founding members of the League of Nations in 1920, and the United Nations in 1945. The Statute of Westminster 1931 formally ended the ability of the UK to pass federal laws without Australia's consent. Australia adopted it in 1942, but it was backdated to 1939 to confirm the validity of legislation passed during World War II. The Australian Capital Territory was formed in 1911 as

13455-446: Was responsible for Japanese operations on mainland New Guinea. The colonial capital of Port Moresby on the south coast of Papua was the strategic key for the Japanese in this area of operations. Capturing it would both neutralize the Allies' principal forward base and serve as a springboard for a possible invasion of Australia . For the same reasons, General Douglas MacArthur , Supreme Commander Allied Forces South West Pacific Area ,

13572-510: Was spotted by an Allied scout plane. By the time the Allied bombers and PT boats finished their work on 3 March, Kimura had lost all eight transports and four of his eight destroyers. The remaining destroyers with about 2,700 surviving troops limped back to Rabaul. According to Morison, the Japanese "...never again risked a transport larger than a small coaster or barge in waters shadowed by American planes. His contemplated offensive against Wau died a-borning." Admiral Isoroku Yamamoto promised

13689-707: Was the overland threat to Port Moresby permanently removed. Since Port Moresby was the only port supporting operations in Papua, its defence was critical to the campaign. The air defences consisted of P-39 and P-40 fighters. Royal Australian Air Force (RAAF) radar could not provide sufficient warning of Japanese attacks, so reliance was placed on coastwatchers and spotters in the hills until an American radar unit arrived in September with better equipment. Japanese bombers were often escorted by fighters which came in at 30,000 ft (9,100 m)—too high to be intercepted by
