Australia.

Australia, officially the Commonwealth of Australia, is a country in the southern hemisphere comprising the mainland of the world's smallest continent, the major island of Tasmania, and numerous other islands in the Indian and Pacific Oceans. Neighbouring countries include Indonesia, East Timor, and Papua New Guinea to the north, the Solomon Islands, Vanuatu, and New Caledonia to the north-east, and New Zealand to the south-east.

For around 40,000 years before European settlement commenced in the late 18th century, the Australian mainland and Tasmania were inhabited by around 250 individual nationsof indigenous Australians. After sporadic visits by fishermen from the immediate north, and European discovery by Dutch explorers in 1606, the eastern half of Australia was claimed by the British in 1770 and initially settled through penal transportation to the colony of New South Wales, founded on 26 January 1788. The population grew steadily in the following years; the continent was explored, and during the 19th century another five largely self-governing Crown Colonies were established.

On 1 January 1901, the six colonies became a federation, and the Commonwealth of Australia was formed. Since Federation, Australia has maintained a stable liberal democratic political system and remains a Commonwealth realm. The population is just over 21.3 million, with approximately 60% concentrated in and around the mainland state capitals of Sydney, Melbourne, Brisbane, Perth, and Adelaide. The nation's capital city is Canberra, located in the Australian Capital Territory (ACT).

Technologically advanced and industrialised, Australia is a prosperous multicultural country and has good results in many international comparisons of national performance such as health care, life expectancy, quality-of-life, human development, public education, economic freedom, and the protection of civil liberties and political rights.Australia's landmass of 7,617,930 square kilometres (2,941,300 sq mi) is on the Indo-Australian Plate. Surrounded by the Indian and Pacific oceans, Australia is separated from Asia by the Arafura and Timor seas. Australia has 34,218 kilometres (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.

The Great Barrier Reef, the world's largest coral reef, lies a short distance off the north-east coast and extends for over 2,000 kilometres (1,240 mi). Mount Augustus, claimed to be the world's largest monolith,is located in Western Australia. At 2,228 metres (7,310 ft), Mount Kosciuszko on the Great Dividing Range is the highest mountain on the Australian mainland, although Mawson Peak on the remote Australian territory of Heard Island is taller at 2,745 metres (9,006 ft).

By far the largest part of Australia is desert or semi-arid lands commonly known as the outback. Australia is the flattest continent, with the oldest and least fertile soils, and is the driest inhabited continent. Only the south-east and south-west corners of the continent have a temperate climate. The population density, 2.8 inhabitants per square kilometre, is among the lowest in the world, although a great proportion of the population lives along the temperate south-eastern coastline. The landscapes of the northern part of the country, with a tropical climate, consist of rainforest, woodland, grassland, mangrove swamps, and desert. The climate is significantly influenced by ocean currents, including the El Niño southern oscillation, which is correlated with periodic drought, and the seasonal tropical low pressure system that produces cyclones in northern Australia.

Climate change has become an increasing concern in Australia in recent years, with many Australians considering it to be the most important issue facing the country. The first Rudd Ministry has initiated several emission reduction activities; Rudd's first official act, on his first day in office, was to sign the instrument of ratification of the Kyoto Protocol. Nevertheless Australia's carbon dioxide emissions per capita are among the highest in the world, lower than only several other industrialised nations including the United States, Canada, and Norway. Rainfall in Australia has increased over the past century, both nationwide and for all four quadrants of the nation. Despite this beneficial effect of climate change, water restrictions are currently in place in many regions and cities of Australia in response to chronic shortages due to urban population increases and localised drought.

History.

Human habitation of Australia is estimated to have begun between 42,000 and 48,000 years ago. These first Australians may have been ancestors of modern Indigenous Australians; they may have arrived via land bridges and short sea-crossings from what is now South-East Asia. Most of these people were hunter-gatherers, with a complex oral culture and spiritual values based on reverence for the land and a belief in the Dreamtime. The Torres Strait Islanders, ethnically Melanesian, were originally horticulturalists and hunter-gatherers. Their cultural practices have always been distinct from those of the Aborigines.

The first recorded European sighting of the Australian mainland was made by the Dutch navigator Willem Janszoon, who sighted the coast of Cape York Peninsula in 1606. During the 17th century, the Dutch charted the whole of the western and northern coastlines of what they called New Holland, but they made no attempt at settlement. In 1770, James Cook sailed along and mapped the east coast of Australia, which he named New South Wales and claimed for Great Britain.

Cook's discoveries prepared the way for establishment of a new penal colony. The British Crown Colony of New South Wales began a settlement at Port Jackson by Captain Arthur Phillip on 26 January 1788. This date was later to become Australia's national day, Australia Day. Van Diemen's Land, now known as Tasmania, was settled in 1803 and became a separate colony in 1825. The United Kingdom formally claimed the western part of Australia in 1829. Separate colonies were created from parts of New South Wales: South Australia in 1836, Victoria in 1851, and Queensland in 1859. The Northern Territory was founded in 1911 when it was excised from South Australia. South Australia was founded as a "free province"—that is, it was never a penal colony. Victoria and Western Australia were also founded "free" but later accepted transported convicts. The transportation of convicts to the colony of New South Wales ceased in 1848 after a campaign by the settlers.The Indigenous Australian population, estimated at 350,000 at the time of European settlement,^[24] declined steeply for 150 years following settlement, mainly because of infectious disease^[25] combined with forced re-settlement and cultural disintegration.^{[citation needed]} The removal of children from their families, which historians such as Henry Reynolds and Indigenous Australians^[which?] have argued could be considered genocide by some definitions,^[26] may have contributed to the decline in the indigenous population.^{[citation needed]} Such interpretations of Aboriginal history are disputed by some commentators as being exaggerated or fabricated for political or ideological reasons.^[27] This debate is known within Australia as the History Wars. Following the 1967 referendum, the Federal government gained the power to implement policies and make laws with respect to Aborigines. Traditional ownership of land—native title—was not recognised until 1992, when the High Court case Mabo v Queensland (No 2) overturned the notion of Australia as terra nullius (literally "no one's land", effectively "empty land") at the time of European occupation.

A gold rush began in Australia in the early 1850s, and the Eureka Stockade rebellion against mining licence fees in 1854 was an early expression of civil disobedience. Between 1855 and 1890, the six colonies individually gained responsible government, 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, defence, and international shipping. On 1 January 1901, federation of the colonies was achieved after a decade of planning, consultation, and voting. The Commonwealth of Australia was born as a dominion of the British Empire. The Federal Capital Territory (later renamed the Australian Capital Territory) was formed from a part of New South Wales in 1911 to provide a location for the proposed new federal capital of Canberra. (Melbourne was the temporary seat of government from 1901 to 1927 while Canberra was being constructed.) The Northern Territory was transferred from the control of the South Australian government to the Commonwealth in 1911. Australia willingly participated in World War I. Many Australians regard the defeat of the Australian and New Zealand Army Corps (ANZACs) at Gallipoli as the birth of the nation—its first major military action. The Kokoda Track Campaign is regarded by many as an analogous nation-defining event during World War II.

Australia adopted it in 1942, but backdated it to the beginning of World War II to confirm the validity of legislation passed by the Australian Parliament during the war. The shock of the UK's defeat in Asia in 1942 and the threat of Japanese invasion caused Australia to turn to the United States as a new ally and protector. Since 1951, Australia has been a formal military ally of the US, under the ANZUS treaty. After World War II, Australia encouraged immigration from Europe; since the 1970s and the abolition of the White Australia policy, immigration from Asia and elsewhere was also encouraged. As a result, Australia's demography, culture, and self-image have been transformed. The final constitutional ties between Australia and the UK were severed with the passing of the Australia Act 1986, ending any British role in the government of the Australian States, and ending judicial appeals to the UK Privy Council At the 1999 referendum, 54% of Australian voters rejected a proposal to become a republic with a president appointed by two-thirds vote of both houses of the Australian Parliament. Since the election of the Whitlam Government in 1972, there has been an increasing focus on the expansion of ties with other Pacific Rim nations while maintaining close ties with Australia's traditional allies and trading partners.
