The country of Australia comprises most of this continent, including the mainland, the island of Tasmania, and numerous smaller islands. The continent also includes the island of New Guinea (Papua New Guinea and Western New Guinea), the Aru Islands, the Ashmore and Cartier Islands, and most of the Coral Sea Islands.

The country also boasts 516 national parks to protect its diverse plant and animal species.
The ancestors of Aboriginal Australians began arriving in Australia from Southeast Asia between 50,000 and 65,000 years ago, and by the time of British settlement, they spoke 250 distinct languages and had one of the oldest living cultures in the world.

The continent of Australia is sometimes known as Sahul, Australinea, or Meganesia
Australia, officially the Commonwealth of Australia, is a country comprising the mainland of the Australian continent, the island of Tasmania, and numerous smaller islands. It is the world's sixth-largest country and the largest in Oceania. Australia is also a continent in its own right, being the smallest of the seven traditional continents.
The continent of Australia is sometimes referred to as Sahul, Australinea, or Meganesia. These names are used to distinguish the continent from the country of Australia. The name 'Sahul' is derived from the Sahul Shelf, which is part of the continental shelf of the Australian continent. Archaeologists often use the name Sahul, while Meganesia tends to be used by zoogeographers. The name Meganesia, meaning "great island" or "great island-group", has been widely accepted by biologists. Australinea was coined by biologist Richard Dawkins in 2004.
The continent of Australia includes mainland Australia, Tasmania, the island of New Guinea (Papua New Guinea and Western New Guinea), the Aru Islands, the Ashmore and Cartier Islands, most of the Coral Sea Islands, and some other nearby islands. The continent includes a continental shelf overlain by shallow seas that divide it into several landmasses—the Arafura Sea and Torres Strait between mainland Australia and New Guinea, and Bass Strait between mainland Australia and Tasmania.
Australia, the country, has a highly developed economy and one of the highest per capita incomes globally. It has abundant natural resources and a well-developed international trade network, with China as its largest trading partner. Australia is also known for its unique flora and fauna, including eucalyptus trees, platypuses, kangaroos, and koalas.

Australia is a federal parliamentary democracy and constitutional monarchy comprising six states and ten territories
Australia is a federal parliamentary democracy and a constitutional monarchy. As a commonwealth of the United Kingdom, Australia's head of state is the British monarch, currently King Charles III. Australians have considered becoming a republic, but in a 1999 vote, they decided to maintain their ties to Britain.
Australia is made up of six states and ten territories. The six states are New South Wales (including Lord Howe Island), Queensland, South Australia, Tasmania (including Macquarie Island), Victoria, and Western Australia. These six states were formed from colonies that federated in 1901 to become the founding states of the Commonwealth of Australia. The ten territories include the Australian Capital Territory, the Northern Territory, Norfolk Island, Ashmore and Cartier Islands, Jervis Bay Territory, and the Coral Sea Islands.
The states are partially sovereign and have their own constitutions, legislatures, executive governments, judiciaries, and law enforcement agencies. The territories are legally subordinate to the federal government, but they can be autonomous and administer local policies and programs. Two territories, the Northern Territory and the Australian Capital Territory, have some degree of self-government, although less than that of the states.
