Australia, officially known as the Commonwealth of Australia, is a sovereign country comprising the mainland of the Australian continent, the island of Tasmania, and numerous smaller islands. It is the largest country in Oceania and the world’s sixth-largest country by total area.
The term Indigenous Australians refers to Aboriginal Australians as well as Torres Strait Islanders, and the term should only be used when both groups are included in the topic being addressed, or by self-identification by a person as Indigenous.
Torres Strait Islanders are ethnically and culturally distinct, despite extensive cultural exchange with some of the Aboriginal groups, and the Torres Strait Islands are mostly part of Queensland but have a separate governmental status.
In the 2016 Australian Census, Indigenous Australians comprised 3.3% of Australia’s population, with 91% of these identifying as Aboriginal only, 5% Torres Strait Islander, and 4% both.
