For about 50,000 years before the first British settlement in the late 18th century, Australia was inhabited by indigenous Australians, who spoke languages grouped into roughly 250 language groups. After the European discovery of the continent by Dutch explorers in 1606, Australia's eastern half was claimed by Great Britain in 1770 and initially settled through penal transportation to the colony of New South Wales from 26 January 1788. The population grew steadily in subsequent decades; the continent was explored and an additional five self-governing crown colonies were established. On 1 January 1901, the six colonies federated, forming the Commonwealth of Australia. Since federation, Australia has maintained a stable liberal democratic political system that functions as a federal parliamentary constitutional monarchy comprising six states and several territories. The population of 24 million is highly urbanized and heavily concentrated in the eastern states and on the coast. Australia is a developed country and one of the wealthiest in the world, with the world's 12th-largest economy. In 2014 Australia had the world's fifth-highest per capital income. Australia's military expenditure is the world's 13th-largest. With the second-highest human development index globally, Australia ranks highly in many international comparisons of national performance, such as quality of life, health, education, economic freedom, and the protection of civil liberties and political rights. Australia is a member of the United Nations, G20, Commonwealth of Nations, ANZUS, Organisation for Economic Co-operation and Development (OECD), World Trade Organization, Asia-Pacific Economic Cooperation, and the Pacific Islands Forum.
Environment
Although most of Australia is semi-arid or desert, it includes a diverse range of habitats from alpine heaths to tropical rainforests, and is recognised as a megadiverse country. 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 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 the greatest number of reptiles of any country, with 755 species. 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 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 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 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 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 3rd out of 178 countries in the world on the 2014 Environmental Performance Index.

Australia is a wealthy country; it generates its income from various sources including mining-related exports, telecommunications, banking and manufacturing. It has a market economy, a relatively high GDP per capita, and a relatively low rate of poverty. In terms of average wealth, Australia ranked second in the world after Switzerland in 2013, although the nation's poverty rate increased from 10.2% to 11.8%, from 2000/01 to 2013. It was identified by the Credit Suisse Research Institute as the nation with the highest median wealth in the world and the second-highest average wealth per adult in 2013. The Australian dollar is the currency for the nation, including Christmas Island, Cocos (Keeling) Islands, and Norfolk Island, as well as the independent Pacific Island states of Kiribati, Nauru, and Tuvalu. With the 2006 merger of the Australian Stock Exchange and the Sydney Futures Exchange, the Australian Securities Exchange became the ninth largest in the world. Ranked third in the Index of Economic Freedom (2010), Australia is the world's twelfth largest economy and has the fifth highest per capital GDP (nominal) at $66,984. The country was ranked second in the United Nations 2011 Human Development Index and first in Legatum's 2008 Prosperity Index. All of Australia's major cities fare well in global comparative livability surveys; Melbourne reached top spot for the fourth year in a row on The Economist's 2014 list of the world's most liveable cities, followed by Adelaide, Sydney, and Perth in the fifth, seventh, and ninth places respectively. Total government debt in Australia is about $190 billion – 20% of GDP in 2010. Australia has among the highest house prices and some of the highest household debt levels in the world. An emphasis on exporting commodities rather than manufactured goods has underpinned a significant increase in Australia's terms of trade since the start of the 21st century, due to rising commodity prices. Australia has a balance of payments that is more than 7% of GDP negative, and has had persistently large current account deficits for more than 50 years. Australia has grown at an average annual rate of 3.6% for over 15 years, in comparison to the OECD annual average of 2.5%. Australia was the only advanced economy not to experience a recession due to the global financial downturn in 2008–2009. However, the economies of six of Australia's major trading partners have been in recession, which in turn has affected Australia, significantly hampering its economic growth in recent years. From 2012 to early 2013, Australia's national economy grew, but some non-mining states and Australia's non-mining economy experienced a recession.The Hawke Government floated the Australian dollar in 1983 and partially deregulated the financial system. The Howard Government followed with a partial deregulation of the labour market and the further privatisation of state-owned businesses, most notably in the telecommunications industry. The indirect tax system was substantially changed in July 2000 with the introduction of a 10% Goods and Services Tax (GST). In Australia's tax system, personal and company income tax are the main sources of government revenue. In May 2012, there were 11,537,900 people employed (either full- or part-time), with an unemployment rate of 5.1%. Youth unemployment (15–24) stood at 11.2%. Data released in mid-November 2013 showed that the number of welfare recipients had grown by 55%. In 2007 228,621 Newstart unemployment allowance recipients were registered, a total that increased to 646,414 in March 2013. According to the Graduate Careers Survey, full-time employment for newly qualified professionals from various occupations has declined since 2011 but it increases for graduates three years after graduation. Since 2008, inflation has typically been 2–3% and the base interest rate 5–6%. The service sector of the economy, including tourism, education, and financial services, accounts for about 70% of GDP.[220] Rich in natural resources, Australia is a major exporter of agricultural products, particularly wheat and wool, minerals such as iron-ore and gold, and energy in the forms of liquified natural gas and coal. Although agriculture and natural resources account for only 3% and 5% of GDP respectively, they contribute substantially to export performance. Australia's largest export markets are Japan, China, the US, South Korea, and New Zealand. Australia is the world's fourth largest exporter of wine, and the wine industry contributes $5.5 billion per year to the nation's economy.
Government and politics
Australia is a federal parliamentary constitutional monarchy with Elizabeth II at its apex as the Queen of Australia, a role that is distinct from her position as monarch of the other Commonwealth realms. The Queen is represented in Australia by the Governor-General at the federal level and by the Governors at the state level, who by convention act on the advice of her ministers. The most notable exercise to date of the Governor-General's reserve powers outside the Prime Minister's request was the dismissal of the Whitlam Government in the constitutional crisis of 1975.
