History of Indigenous Australians


The history of Aboriginal Australians is thought to have spanned 30,000 to 45,000 years, although some estimates have put the figure at up to 60,000 years before European settlement. The Aboriginal Australians lived with a strong dependence on the land, and also the water. Each group developed skills for the area in which they would live – hunting or fishing or gathering.

In the early 1900s it was commonly believed that the Indigenous population of Australia was going to become extinct.

There are no clear tribes or an accepted origin of the indigenous people of Australia, although they are believed to be among the earliest human migrations out of Africa. Although they likely migrated to Australia through Southeast Asia they are not demonstrably related to any known Asian or Polynesian population. There is evidence of genetic and linguistic interchange between Australians in the far north and the Austronesian peoples of modern-day New Guinea and the islands, but this may be the result of recent trade and intermarriage.

It is believed that the first human migration to Australia was achieved when this landmass formed part of the Sahul continent, connected to the island of New Guinea via a land bridge. It is also possible that people came by island hopping via an island chain between Sulawesi and New Guinea and the other reaches North Western Australia via Timor. The exact timing of the arrival of the ancestors of the Aboriginal Australians has been a matter of dispute among archaeologists. The most generally accepted date for first arrival is between 40,000–80,000 years BP. Near Penrith in New South Wales, since 1971 numerous Aboriginal stone tools have been found in Cranebrook Terraces gravel sediments having dates of 45,000 to 50,000 years BP. When these results were new they were controversial, but more recent dating of the same strata in 1987 and 2003 has corroborated these dates. A 48,000 BC date is based on a few sites in northern Australia dated using thermoluminescence. A large number of sites have been radiocarbon dated to around 38,000 BC, leading some researchers to doubt the accuracy of the thermoluminescence technique. Radiocarbon dating is limited to a maximum age of around 40,000 years. Some estimates have been given as widely as from 30,000 to 68,000 BC. Earlier dates are requiring new techniques such as optically stimulated luminescence (OSL) and accelerator mass spectrometry (AMS), and the evidence for an earlier date of arrival is growing. Charles Dortch has dated recent finds on Rottnest Island, Western Australia at 70,000 years BP. The rock shelters at Malakunanja II (a shallow rock-shelter about 50 kilometres inland from the present coast) and of Nauwalabila I (70 kilometres further south) show evidence of used pieces of ochre – evidence for paint used by artists 60,000 years ago. Using OSL Rhys Jones has obtained a date for stone tools in these horizons dating from 53,000–60,000 years ago.
