Aboriginal Australians

Aboriginal Australians are the various indigenous peoples of the Australian mainland and many of its islands, excluding the ethnically distinct people of the Torres Strait Islands.

Humans first migrated to Australia 50,000 to 65,000 years ago, and over time formed as many as 500 linguistic and territorial groups. Aboriginal people once lived across large areas of the continental shelf that were later inundated by postglacial sea-level rise at the start of the Holoceneinter-glacial period, reshaping coastal landscapes and separating Tasmania from the mainland. Aboriginal people maintained extensive networks within the continent and certain groups maintained relationships with Torres Strait Islanders and the Makassar people of modern-day Indonesia.

Over the millennia, Aboriginal people developed complex trade networks, inter-cultural relationships, law and religions, which make up some of the oldest continuous cultures in the world. At the time of European colonisation of Australia, the Aboriginal people spoke more than 250 different languages, possessed varying degrees of technology, and lived in various types of settlements. Languages (or dialects) and language-associated groups of people are connected with stretches of territory known as "Country", with which they have a profound spiritual connection.

Contemporary Aboriginal beliefs are shaped by traditional beliefs, the disruption of colonisation, religions brought to the continent by later migrants, and contemporary issues. Just over half hold secular or other spiritual beliefs or no religious affiliation; about 40% are Christian; and about 1% adhere to a traditional Aboriginal religion. Traditional cultural beliefs are passed down and shared through dancing, stories, songlines, and art that collectively weave an ontology of modern daily life and ancient creation known as the Dreaming.

Studies of Aboriginal groups' genetic makeup are ongoing, but evidence suggests that they have genetic inheritance from ancient Asian peoples. Aboriginal Australians and Papuans shared the same paleocontinentSahul, although they became genetically distinct about 37,000 years ago. Aboriginal Australians have a broadly shared, complex genetic history, but only in the last 200 years have they been defined by others as, and started to self-identify as, a single group. Aboriginal identity has changed over time and place, with family lineage, self-identification, and community acceptance all of varying importance.

The 2021 census shows that there were 944,171 Aboriginal people, comprising 3.7% of Australia's population. Over 80% of Aboriginal people today speak English at home, and about 77,000 speak an Indigenous language at home. Aboriginal people, along with Torres Strait Islander people, suffer a number of severe health and economic deprivations in comparison with the wider Australian community.
