Their definition does not include Australia's subantarctic external territory Heard Island and McDonald Islands , but
11400-558: 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
11550-511: The Australian mainland. The flora of New Guinea is a mixture of many tropical rainforest species with origins in Asia, such as Castanopsis acuminatissima , Lithocarpus spp., elaeocarps , and laurels , together with typically Australasian flora. In the New Guinean highlands, conifers such as Dacrycarpus , Dacrydium , Papuacedrus and Libocedrus are present. For many species,
11700-555: The New World (consisting of North America and South America) and the Old World (consisting of Africa, Asia and Europe). In his 1879 book Australasia , British naturalist Alfred Russel Wallace commented that, "Oceania is the word often used by continental geographers to describe the great world of islands we are now entering upon" and that "Australia forms its central and most important feature." He did not explicitly label Oceania
11850-520: The Oceanian sub-region known as Australasia , with New Guinea being in Melanesia . The continent includes a continental shelf overlain by shallow seas which divide it into several landmasses—the Arafura Sea and Torres Strait between mainland Australia and New Guinea, and Bass Strait between mainland Australia and Tasmania. When sea levels were lower during the Pleistocene ice age , including
12000-562: The South Pacific in the early part of the 16th century. On 23 April 1770, British explorer James Cook made his first recorded direct observation of indigenous Australians at Brush Island near Bawley Point . On 29 April, Cook and crew made their first landfall on the mainland of the continent at a place now known as the Kurnell Peninsula . It is here that James Cook made first contact with an Aboriginal tribe known as
12150-713: The States. With the encouragement of Queensland, in 1884, a British protectorate had been proclaimed over the southern coast of New Guinea and its adjacent islands. British New Guinea was annexed outright in 1888. The possession was placed under the authority of the newly federated Commonwealth of Australia in 1902 and with passage of the Papua Act of 1905, British New Guinea became the Australian Territory of Papua , with formal Australian administration beginning in 1906. The Bombing of Darwin on 19 February 1942
12300-632: The centre and Phanerozoic sedimentary basins , metamorphic and igneous rocks in the east. The Australian mainland and Tasmania are situated in the middle of the tectonic plate and have no active volcanoes, but due to passing over the East Australia hotspot , recent volcanism has occurred during the Holocene , in the Newer Volcanics Province of western Victoria and south-eastern South Australia. Volcanism also occurs in
12450-545: 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
12600-467: The combined landmass of Sahul . The name "Sahul" derives from the Sahul Shelf , which is a part of the continental shelf of the Australian continent. During the past 18,000 to 10,000 years, rising sea levels overflowed the lowlands and separated the continent into today's low-lying arid to semi-arid mainland and the two mountainous islands of New Guinea and Tasmania. With a total land area of 8.56 million square kilometres (3,310,000 sq mi),
12750-415: The continent are endemic to Australia. This high level of endemism can be attributed to the continent's long geographic isolation, tectonic stability, and the effects of an unusual pattern of climate change on the soil and flora over geological time. Australia and its territories are home to around 800 species of bird; 45% of these are endemic to Australia. Predominant bird species in Australia include
12900-552: The continent other than those of Austronesian family. Predominant languages include English in Australia, Tok Pisin in Papua New Guinea, and Indonesian (Malay) in Indonesian New Guinea. Immigration to Australia have brought overseas languages such as Italian , Greek , Arabic , Filipino , Mandarin , Vietnamese and Spanish , among others. Contact between Austronesian and Papuan resulted in several instances in mixed languages such as Maisin . Tok Pisin
13050-541: The continent. Ancient Greek philosopher Aristotle speculated of a large landmass in the southern hemisphere, saying, "Now since there must be a region bearing the same relation to the southern pole as the place we live in bears to our pole...". His ideas were later expanded by Ptolemy (2nd century AD), who believed that the lands of the Northern Hemisphere should be balanced by land in the south . The theory of balancing land has been documented as early as
13200-784: 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,
13350-594: 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
13500-428: The draft constitution, and Australia, the outgoing metropolitan power, had thought that Papua New Guinea would not remain a monarchy. The founders, however, considered that imperial honours had a cachet. The monarch is represented by the Governor-General of Papua New Guinea , currently Bob Dadae . Papua New Guinea (along with Solomon Islands ) is unusual among Commonwealth realms in that governors-general are elected by
13650-459: The early 2010s after the 2000s Australian drought . 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
13800-560: The east coast and Mediterranean climate in the west. The northern parts of the country have a tropical climate . Snow falls frequently on the highlands near the east coast, in the states of Victoria , New South Wales , Tasmania and in the Australian Capital Territory . Temperatures in Australia have ranged from above 50 °C (122 °F) to well below 0 °C (32 °F). Nonetheless, minimum temperatures are moderated. The El Niño-Southern Oscillation
13950-488: The end of the Last Glacial Maximum around 10,000-15,000 years ago, the sea levels rose and covered the St. Vincent basin. To the south it is defined by a line from Troubridge Point on Yorke Peninsula to Cape Jervis on Fleurieu Peninsula. Its entrances from the southwest are from Investigator Strait , and to the southeast from Backstairs Passage , which separate Kangaroo Island from the mainland. Adelaide lies midway along
14100-490: The establishment of the penal colony of New South Wales . By the mid-19th century, most of 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
14250-461: The few regions close to the equator that experience snowfall , which occurs in the most elevated parts of the mainland. Some areas in the island experience an extraordinary amount of precipitation, averaging roughly 4,500 millimetres (180 in) of rainfall annually. The Australian landmass's climate is mostly desert or semi-arid , with the southern coastal corners having a temperate climate, such as oceanic and humid subtropical climate in
14400-415: The financial year 2014/15, tourism represented 3.0% of Australia 's GDP contributing A$ 47.5 billion to the national economy. In 2015, there were 7.4 million visitor arrivals. Mercer Quality of Living Survey ranks Sydney tenth in the world in terms of quality of living , making it one of the most livable cities . It is classified as an Alpha+ World City by GaWC . Melbourne also ranked highly in
14550-629: The first European to explore the Strait. When Europeans first arrived, inhabitants of New Guinea and nearby islands, whose technologies included bone, wood, and stone tools, had a productive agricultural system. In 1660, the Dutch recognised the Sultan of Tidore 's sovereignty over New Guinea . The first known Europeans to sight New Guinea were probably the Portuguese and Spanish navigators sailing in
14700-772: 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
14850-495: The globe. Animal groups such as macropods , monotremes , and cassowaries are endemic to Australia. There were three main reasons for the enormous diversity that developed in animal, fungal and plant life. Although New Guinea is the most northerly part of the continent, and could be expected to be the most tropical in climate, the altitude of the New Guinea highlands is such that a great many animals and plants that were once common across Australia–New Guinea now survive only in
15000-543: The gulf's east shore. Other towns located on the gulf, from west to east include Edithburgh , Port Vincent , Ardrossan and Port Wakefield and Normanville . The Aboriginal name given to it by the original inhabitants of the area, the Kaurna people was Wongajerla , also spelt Wongga Yerlo or Wonggayerlo , meaning "western sea". It was named Gulph of St. Vincent by Matthew Flinders on 30 March 1802, in honour of Admiral John Jervis (1st Earl of St Vincent) who won
15150-412: 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
15300-481: The high and rugged mountains of New Guinea and, by reverse (downwards) buckling, the Torres Strait that now separates the two main landmasses. The collision also pushed up the islands of Wallacea , which served as island 'stepping-stones' that allowed plants from Southeast Asia 's rainforests to colonise New Guinea, and some plants from Australia–New Guinea to move into Southeast Asia. The ocean straits between
15450-479: 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
15600-417: 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
15750-461: The islands were narrow enough to allow plant dispersal, but served as an effective barrier to exchange of land mammals between Australia–New Guinea and Asia. Among the fungi, the remarkable association between Cyttaria gunnii (one of the "golf-ball" fungi) and its associated trees in the genus Nothofagus is evidence of that drift: the only other places where this association is known are New Zealand and southern Argentina and Chile . Due to
15900-477: The largest Greek-speaking population outside of Europe , and the second largest Asian population in Australia after Sydney. Australia is the only First World country on the Australia-New Guinea continent, although the economy of Australia is by far the largest and most dominant economy in the region and one of the largest in the world. Australia's per-capita GDP is higher than that of
16050-695: The legislature, rather than chosen by the executive branch. Since 1788, the primary influence behind Australian culture has been Anglo-Celtic Western culture , with some Indigenous influences. The divergence and evolution that has occurred in the ensuing centuries has resulted in a distinctive Australian culture. Since the mid-20th century, American popular culture has strongly influenced Australia, particularly through television and cinema. Other cultural influences come from neighbouring Asian countries, and through large-scale immigration from non-English-speaking nations. The Australian Museum in Sydney and
16200-494: 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
16350-541: The long-established broad-leaf deciduous forest began to give way to the distinctive hard-leaved sclerophyllous plants that characterise the modern Australian landscape. Typical Southern Hemisphere flora include the conifers Podocarpus (eastern Australia and New Guinea), the rainforest emergents Araucaria (eastern Australia and New Guinea), Nothofagus (New Guinea and Tasmania ) and Agathis (northern Queensland and New Guinea), as well as tree ferns and several species of Eucalyptus . Prominent features of
16500-448: 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
16650-616: The mainland. Then between about 8,000 and 6,500 BC, the lowlands in the north were flooded by the sea, separating the Aru Islands , mainland Australia, New Guinea , and Tasmania. A northern arc consisting of the New Guinea Highlands , the Raja Ampat Islands , and Halmahera was uplifted by the northward migration of Australia and subduction of the Pacific Plate . The Outer Banda Arc was accreted along
16800-474: 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
16950-487: The name Australinea in 2004. Australia–New Guinea has also been used. The Australian continent, as a whole being part of the Australian Plate , is the lowest, flattest, and oldest landmass on Earth and it has had a relatively stable geological history. New Zealand is not part of the continent of Australia, but of the separate, submerged continent of Zealandia . New Zealand and Australia are both part of
17100-610: The name Sahul was extended from its previous use for just the Sahul Shelf to cover the continent. In 1984, the name Meganesia was suggested, meaning "great island" or "great island-group", for both the Pleistocene continent and the present-day lands, and this name has been widely accepted by biologists. Others have used Meganesia with different meanings: travel writer Paul Theroux included New Zealand in his definition and others have used it for Australia, New Zealand and Hawaii . Another biologist, Richard Dawkins , coined
17250-432: The name of Oceania. There are thus six great divisions of the earth — Europe , Asia , Africa , North America, South America and Oceania." The American author Samuel Griswold Goodrich wrote in his 1854 book History of All Nations that, "geographers have agreed to consider the island world of the Pacific Ocean as a third continent, under the name Oceania." In this book the other two continents were categorized as being
17400-602: 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,
17550-511: The northwestern edge the continent; it includes the islands of Timor , Tanimbar , and Seram . Papua New Guinea has several volcanoes , as it is situated along the Pacific Ring of Fire . Volcanic eruptions are not rare, and the area is prone to earthquakes and tsunamis because of this. Mount Wilhelm in Papua New Guinea is the second highest mountain in the continent, and at 4,884 metres (16,024 ft) above sea level , Puncak Jaya
17700-407: The only continent with this distinction. The lands were joined with Antarctica as part of the southern supercontinent Gondwana until the plate began to drift north about 96 million years ago. For most of the time since then, Australia–New Guinea remained a continuous landmass. When the last glacial period ended in about 10,000 BC, rising sea levels formed Bass Strait , separating Tasmania from
17850-428: 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
18000-535: The primary refuge was the relatively cool and well-watered Great Dividing Range . Even today, pockets of remnant vegetation remain in the cool uplands, some species not much changed from the Gondwanan forms of 60 or 90 million years ago. Eventually, the Australia–New Guinea tectonic plate collided with the Eurasian plate to the north. The collision caused the northern part of the continent to buckle upwards, forming
18150-594: 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
18300-528: The publication of Baudin's map preceded that of Flinders by three years. The Adelaide Desalination Plant which is located on Gulf St Vincent's eastern shore in Lonsdale , supplies the Adelaide metropolitan area with desalinated water from the gulf. It officially opened in 2013. The Gulf teems with crustacea and polychaeta , as well as various species of sea squirts and sea urchins . The benthos
18450-480: 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
18600-545: 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
18750-419: 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
18900-491: 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
19050-549: 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
19200-543: The seventh century, and archipelagic rule of New Guinea by the 13th. At the beginning of the seventh century, the Sumatra -based empire of Srivijaya (7th century–13th century) engaged in trade relations with western New Guinea, initially taking items like sandalwood and birds-of-paradise in tribute to China , but later making slaves out of the natives. The rule of the Java -based empire of Majapahit (1293–1527) extended to
19350-565: The spread of animals, fungi and plants across the single Pleistocene landmass the separate lands have a related biota . There are over 300 bird species in West Papua , of which at least 20 are unique to the ecoregion, and some live only in very restricted areas. These include the grey-banded munia , Vogelkop bowerbird , and the king bird-of-paradise . Australia has a huge variety of animals; some 83% of mammals , 89% of reptiles , 24% of fish and insects and 93% of amphibians that inhabit
19500-741: 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
19650-406: 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
19800-1029: 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
19950-527: The tone for the bitter final stages of the New Guinea campaign , which persisted into 1945. The offensives in Papua and New Guinea of 1943–44 were the single largest series of connected operations ever mounted by the Australian armed forces. Following the 1998 commencement of reforms across Indonesia , Papua and other Indonesian provinces received greater regional autonomy. In 2001, "Special Autonomy" status
20100-558: The tropical highlands where they are severely threatened by population growth . In New Guinea, the climate is mostly monsoonal (December to March), southeast monsoon (May to October), and tropical rainforest with slight seasonal temperature variation. In lower altitudes, the temperature is around 27 °C (81 °F) year round. But the higher altitudes, such as Mendi , are constantly around 21 °C (70 °F) with cool lows nearing 11 °C (52 °F), with abundant rainfall and high humidity. The New Guinea Highlands are one of
20250-517: The western fringes of New Guinea. Recent archaeological research suggests that 50,000 years ago people may have occupied sites in the highlands at New Guinean altitudes of up to 2,000 m (6,600 ft), rather than being restricted to warmer coastal areas. Legends of Terra Australis Incognita—an "unknown land of the South"—date back to Roman times and before, and were commonplace in medieval geography, although not based on any documented knowledge of
20400-721: The world". In 1883, the Colony of Queensland tried to annex the southern half of eastern New Guinea, but the British government did not approve. The Commonwealth of Australia came into being when the Federal Constitution was proclaimed by the Governor-General , Lord Hopetoun , on 1 January 1901. From that point a system of federalism in Australia came into operation, entailing the establishment of an entirely new national government (the Commonwealth government) and an ongoing division of powers between that government and
20550-522: The world". In the Pacific Ocean Handbook (1945), author Eliot Grinnell Mears wrote that he categorized Australia, New Zealand and Pacific islands under the label of Oceania for "scientific reasons; Australia's fauna is largely continental in character, New Zealand's are clearly insular; and neither Commonwealth realm has close ties with Asia." He further added that, "the term Australasia is not relished by New Zealanders and this name
20700-532: The world's continents in English-speaking countries. Scottish cartographer John Bartholomew wrote in 1873 that, "the New World consists of North America , and the peninsula of South America attached to it. These divisions [are] generally themselves spoken as continents, and to them has been added another, embracing the large island of Australia and numerous others in the [Pacific] Ocean, under
20850-438: The world's known total. New Guinea has 578 species of breeding birds, of which 324 species are endemic. Bird life also flourished—in particular, the songbirds (order Passeriformes , suborder Passeri) are thought to have evolved 50 million years ago in the part of Gondwana that later became Australia , New Zealand, New Guinea , and Antarctica , before radiating into a great number of different forms and then spreading around
21000-419: The world's oldest known cremations , thus indicating early evidence for religious ritual among humans. Dreamtime remains a prominent feature of Australian Aboriginal art , the oldest continuing tradition of art in the world. Papuan habitation is estimated to have begun between 42,000 and 48,000 years ago in New Guinea. Trade between New Guinea and neighboring Indonesian islands was documented as early as
21150-530: The world. It is also one of the most rural, as only 18 percent of its people live in urban centres. West Papua , a region in Indonesia, is home to an estimated 44 uncontacted tribal groups . Australia, the largest landmass in the continent, is highly urbanised , and has the world's 14th-largest economy with the second-highest human development index globally. Australia also has the world's 9th largest immigrant population . The continent of Oceania
21300-531: 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,
21450-615: 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
21600-451: Was almost completely isolated. During this time, the continent experienced numerous changes in climate, but the overall trend was towards greater aridity. When South America eventually separated from Antarctica, the development of the cold Antarctic Circumpolar Current changed weather patterns across the world. For Australia–New Guinea, it brought a marked intensification of the drying trend. The great inland seas and lakes dried out. Much of
21750-413: 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
21900-533: Was granted to Papua province, although to date, implementation has been partial and often criticised. The region was administered as a single province until 2003, when it was split into the provinces of Papua and West Papua . Elections in 1972 resulted in the formation of a ministry headed by Chief Minister Michael Somare , who pledged to lead the country to self-government and then to independence. Papua New Guinea became self-governing on 1 December 1973 and achieved independence on 16 September 1975. The country joined
22050-516: 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.
