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 the last glacial period . By the time of British settlement, Aboriginal Australians spoke 250 distinct languages and had
7931-494: 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
8034-418: The loss of any of the party's members' lives. This contrasts with the ill-fated Burke and Wills expedition in 1860–61 which was much better funded, but resulted in the deaths of three of the members of the transcontinental party. The Overland Telegraph line was constructed in the 1870s along the route identified by Stuart. In 1865, the surveyor George Goyder , using changes in vegetation patterns, mapped
8137-448: 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
8240-474: 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
8343-602: 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,
8446-498: 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 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
8549-428: 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
8652-610: The present day noun form. It is colloquially said that "the outback" is located "beyond the Black Stump ". The location of the black stump may be some hypothetical location or may vary depending on local custom and folklore. It has been suggested that the term comes from the Black Stump Wine Saloon that once stood about 10 kilometres (6.2 mi) out of Coolah, New South Wales on the Gunnedah Road. It
8755-594: 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
8858-480: 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
8961-545: 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
9064-419: 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
9167-491: 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
9270-741: 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
9373-406: 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
9476-478: The track can still be destroyed by flash flooding and drifting sand. In dry conditions, a shorter route at the northern end depicted on maps as the "Inside track" saves 35 kilometres in distance. Other than this, the road has no major intersections. Fuel, supplies and facilities, including a hotel, can be found on the track at the Mungeranie station, 204 km from Marree and 313 km from Birdsville. It
9579-497: The world's major manganese mines. Aboriginal communities in outback regions, such as the Anangu Pitjantjatjara Yankunytjatjara lands in northern South Australia, have not been displaced as they have been in areas of intensive agriculture and large cities, in coastal areas. The total population of the Outback in Australia declined from 700,000 in 1996 to 690,000 in 2006. The largest decline
9682-516: The world's natural supply, but was closed down in 2020 due to financial reasons. The Pilbara region's economy is dominated by mining and petroleum industries. The Pilbara's oil and gas industry is the region's largest export industry, earning $ 5.0 billion in 2004/05 and accounting for over 96% of the State's production. Most of Australia's iron ore is also mined in the Pilbara and it also has one of
9785-457: The years the Birdsville track became one of the country's most isolated and best-known stock routes, as well as a mail route made famous by outback legend Tom Kruse . Tom Kruse and the track were immortalised in The Back of Beyond , the 1954 documentary film made by John Heyer . Kruse's services ceased in 1963, replaced by an air service from Adelaide that started in 1970. In 2006, as part of
9888-615: 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
9991-527: Was built to restrict movements of dingoes and wild dogs into agricultural areas towards the south east of the continent. The marginally fertile parts are primarily utilised as rangelands and have been traditionally used for sheep or cattle grazing, on cattle stations which are leased from the Federal Government. While small areas of the outback consist of clay soils the majority has exceedingly infertile palaeosols . Riversleigh , in Queensland,
10094-425: Was declared the Year of the Outback. While the early explorers used horses to cross the Outback, the first woman to make the journey riding a horse was Anna Hingley , who rode from Broome to Cairns in 2006. The paucity of industrial land use has led to the Outback being recognised globally as one of the largest remaining intact natural areas on Earth. Global " Human Footprint " and wilderness reviews highlight
10197-413: 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
10300-544: Was in the Outback Northern Territory , while the Kimberley and Pilbara showed population increases during the same period. The sex ratio is 1040 males for 1000 females and 17% of the total population is indigenous. The Royal Flying Doctor Service (RFDS) started service in 1928 and helps people who live in the outback of Australia. Previously, serious injuries or illnesses often meant death owing to
10403-579: 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
10506-470: Was popularised by the explorer Matthew Flinders , who said it 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
10609-458: Was sporadic. More focus was on the more accessible and fertile coastal areas. The first party to successfully cross the Blue Mountains just outside Sydney was led by Gregory Blaxland in 1813, 25 years after the colony was established. People, starting with John Oxley in 1817, 1818 and 1821, followed by Charles Sturt from 1829 to 1830, attempted to follow the westward-flowing rivers to find an "inland sea", but these were found to all flow into
