The early inhabitants of Australia were the ancestors of today’s Aboriginal Australians , who arrived on the continent tens of thousands of years before European colonisation.

Who they were

  • These first peoples are known collectively as Indigenous Australians , comprising hundreds of distinct Aboriginal language and cultural groups spread across the mainland and nearby islands.
  • The Torres Strait Islander peoples , whose ancestors came from what is now Papua New Guinea around 2,500 years ago, are also recognised as early inhabitants of the northern maritime region of the continent.

When they arrived

  • Archaeological sites such as Madjedbebe in Arnhem Land show human activity as early as about 65,000 years ago , making Aboriginal Australians among the oldest continuous cultures on Earth.
  • Other key sites (for example Lake Mungo and rock shelters in Western Australia) support a timeline of roughly 40,000–60,000 years of continuous habitation.

Where they came from

  • Genetic and archaeological evidence indicates that the ancestors of Aboriginal Australians migrated from mainland Asia through insular Southeast Asia , using short sea crossings or island‑hopping routes to reach the ancient landmass that included New Guinea and Australia.
  • They are part of an early “southern route” dispersal of modern humans out of Africa, later diverging into groups that also gave rise to Papuans and other Australasian populations.

Cultural legacy

  • These early inhabitants developed complex kinship systems, oral traditions (Dreaming stories), and sophisticated land‑management practices that have persisted in many communities to the present day.
  • Their long‑term connection to “Country” is now widely acknowledged in Australian public life, including in official recognition of Aboriginal and Torres Strait Islander peoples as the First Peoples of Australia.
