Australia, officially the Commonwealth of Australia, is a country in the Southern Hemisphere comprising the mainland of the Australian continent, the island of Tasmania and numerous smaller islands in the Indian and Pacific Oceans. Neighboring countries include Indonesia, East Timor and Papua New Guinea to the north, the Solomon Islands, Vanuatu and New Caledonia to the northeast and New Zealand to the southeast.

For at least 40,000 years before European settlement in the late 18th century, Australia was inhabited by indigenous Australians, who belonged to one or more of roughly 250 language groups. After discovery by Dutch explorers in 1606, Australia's eastern half was claimed by Britain in 1770 and initially settled through penal transportation to the colony of New South Wales, where formal possession of the land had been taken on 26 January 1788. The population grew steadily in subsequent decades; the continent was explored and an additional five self-governing Crown Colonies were established.

Australia has six states—New South Wales, Queensland, South Australia, Tasmania, Victoria, and Western Australia—and two major mainland territories—the Northern Territory and the Australian Capital Territory (ACT). In most respects these two territories function as states, but the Commonwealth Parliament can override any legislation of their parliaments. By contrast, federal legislation overrides state legislation only in areas that are set out in Section 51 of the Australian Constitution; state parliaments retain all residual legislative powers, including those over schools, state police, the state judiciary, roads, public transport, and local government, since these do not fall under the provisions listed in Section 51.

Australia has a market economy with high GDP per capita and low rate of poverty. 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. After the 2006 merger of the Australian Stock Exchange and the Sydney Futures Exchange, the Australian Securities Exchange is now the ninth largest in the world.

The food of Indigenous Australians was largely influenced by the area in which they lived. Most tribal groups subsisted on a simple hunter-gatherer diet, hunting native game and fish and collecting native plants and fruit. The general term for native Australian flora and fauna used as a source of food is bush tucker. The first settlers introduced British food to the continent which much of what is now considered typical Australian food is based on the Sunday roast has become an enduring tradition for many Australians. Since the beginning of the 20th century, food in Australia has increasingly been influenced by immigrants to the nation, particularly from Southern European and Asian cultures. Australian wine is produced in 60 distinct production areas totaling approximately 160,000 hectares, mainly in the southern, cooler parts of the country. The wine regions in each of these states produce different wine varieties and styles that take advantage of local climates and soil types. The predominant varieties are Shiraz, Cabernet Sauvignon, Chardonnay, Merlot, Sémillon, Pinot noir, Riesling, and Sauvignon blanc. In 1995, an Australian red wine, Penfolds Grange, won the Wine Spectator award for Wine of the Year, the first time a wine from outside France or California achieved this distinction.
