Concept
Indigenous Australians are people with familial heritage from, and membership in, the ethnic groups that lived in areas within the Australian continent before British colonisation. They consist of two distinct groups: the Aboriginal peoples of the Australian mainland and Tasmania, and the Torres Strait Islander peoples from the seas between Queensland and Papua New Guinea. The term Aboriginal and Torres Strait Islander peoples or the person's specific cultural group, is often preferred, though the terms First Nations of Australia, First Peoples of Australia and First Australians are also increasingly common; 812,728 people self-identified as being of Aboriginal and/or Torres Strait Islander origin in the 2021 Australian Census, representing 3.2% of the total population of Australia. Of these Indigenous Australians, 91.4% identified as Aboriginal; 4.2% identified as Torres Strait Islander; while 4.4% identified with both groups. Since 1995, the Australian Aboriginal flag and the Torres Strait Islander flag have been official flags of Australia. The time of arrival of the first human beings in Australia is a matter of debate and ongoing investigation. The earliest conclusively human remains found in Australia are those of Mungo Man LM3 and Mungo Lady, which have been dated to around 50,000 years BP. Although, Indigenous Australians have most likely been living in Australia for upwards of 65,000 years. Isolated for millennia by rising sea water after the last Ice Age, Australian Aboriginal peoples developed a variety of regional cultures and languages, invented distinct artistic and religious traditions, and affected the environment of the continent in a number of ways through hunting, fire farming, and the introduction of the dog. Technologies for warfare and hunting like the boomerang and spear were constructed of natural materials, as were musical instruments like the didgeridoo. Although there are a number of cultural commonalities among Indigenous Australians, there is also a great diversity among different communities.
