For 2023, the best available official figure is still the 2021 estimate: about 983,700 Aboriginal and Torres Strait Islander people , or 3.8% of Australia’s population. That is the commonly cited national Indigenous population figure used in 2023 sources.

Quick note

If you mean Aboriginal people only rather than Aboriginal and Torres Strait Islander people combined, the 2021 Census-based estimate was about 901,700 Aboriginal people.

Context

  • The Australian Bureau of Statistics publication released in 2023 states 983,700 Aboriginal and Torres Strait Islander people at 30 June 2021.
  • Another 2023 source repeats the same figure and says this group represented 3.8% of the total Australian population.

If you want, I can also give you the 2023 population by state or territory in a table.
