Australia (Let's Kill Hitler)

Australia (/ɒˈstreɪliə/, /ə-/, colloquially /-jə/), officially the Commonwealth of Australia, is an Oceanian country comprising the mainland of the Australian continent, the island of Tasmania, Papua New Guinea, the Japanese islands of Shikoku and Kyushu, the Ryukyu Islands, and numerous smaller islands. It is the world's sixth-largest country by total area. Neighbouring countries to the Australian mainland include Indonesia, and East Timor to the north; the Solomon Islands and Vanuatu to the north-east; and New Zealand to the south-east. Bordering Australia's Japanese possessions are the United States' Honshu Territory to the north and the People's Republic of China to the west.

For at least 40,000 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 democracy and constitutional monarchy comprising seven states and several territories. The population of 49.8 million is highly urbanised and heavily concentrated in the eastern states and on the coast of the mainland, as well as in Kyushu-Shikoku.

Australia is a developed country and one of the wealthiest in the world, with the world's 12th-largest economy. 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.
