Aboriginal Australian identity, sometimes known as Aboriginality, is the perception of oneself as Aboriginal Australian, or the recognition by others of that identity. Aboriginal Australians are one of two Indigenous Australian groups of peoples, the other being Torres Strait Islanders. There has also been discussion about the use of "Indigenous" vs "Aboriginal", or more specific group names (which are many and based on varied criteria), such as Murri or Noongar (demonyms), Kaurna or Yolngu (and subgroups), based on language, or a clan name. Usually preference of the person(s) in question is used, if known.
The term "Aboriginal" was coined by white settlers in Australia in the 1830s, after they began to adopt the term "Australian" to define themselves. No real attempt to define the term legally was made until the 1980s, despite use of the term twice in the 1901 Constitution of Australia, before these were removed following the 1967 referendum. Various legal and administrative definitions have been used over the years. A leading judgment by Justice Brennan in the 1992 Mabo v Queensland (No 2) case (which relates to Indigenous of the Torres Strait exclusively) stated that an Indigenous identity of a person depends on a three-part test: biological descent from the Indigenous people; recognition of the person's membership by that person; and recognition by the elders or other persons enjoying traditional authority among those people. This is still in use today.
Various factors affect Aboriginal people's self-identification as Aboriginal, including a growing pride in culture, solidarity in a shared history of dispossession (including the Stolen Generations), and, among those are fair-skinned, an increased willingness to acknowledge their ancestors, once considered shameful. Aboriginal identity can be politically controversial in contemporary discourse, among both Aboriginal and non-Aboriginal people. Successive censuses have shown those identifying as Indigenous (Aboriginal and/or Torres Strait Islander) at a rate far exceeding the growth of the whole Australian population.
