  This outline of Australia is an overview of and topical guide to various aspects of the country of Australia.
  Australia refers to both the continent of Australia and to the Commonwealth of Australia, the sovereign country.
  The continent of Australia, the world's smallest continent, is in the Southern Hemisphere and borders both the Indian Ocean and the Pacific Ocean.
  The Commonwealth of Australia comprises the mainland of the Australian continent, the major island of Tasmania, other nearby islands, and various external territories.
  Neighbouring countries are 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.
  The Australian mainland has been inhabited for at least 50,000 years by Aboriginal Australians.
