Aborigines - Indigenous Australians.Indigenous Australians are descendants of the first known human inhabitants of the Australian continent and its nearby islands. The term includes both the Torres Strait Islanders and the Aboriginal People, who together make up about 2.4% of Australia's modern population. The latter term is usually used to refer to those who live in mainland Australia, Tasmania, and some of the other adjacent islands. The Torres Strait Islanders are indigenous to the Torres Strait Islands between Australia and New Guinea. Indigenous Australians are recognized to have arrived between 70,000 and 40,000 years ago, though the lower end of this range (50,000 BC) has wider acceptance.
