when did the aboriginal tribes arrive in australia
Indigenous Australians Indigenous Australians are the Aboriginal and Torres Strait Islander people of Australia, descended from groups that existed in Australia and surrounding islands prior to British colonisation. The time of arrival of the first Indigenous Australians is a matter of debate among researchers. The earliest definitely human remains found in Australia are those of Mungo Man LM3 and Mungo Lady, which have been dated to around 50,000 years BP.[2] Recent archaeological evidence from the analysis of charcoal and artifacts revealing human use has pushed this date back further to around 65,000 B.P. [3][4] Luminescence dating has suggested habitation in Arnhem Land as far back as 60,000 years BP.[5] Genetic research has inferred a date of habitation as early as 80,000 years BP. Other estimates have ranged up to 100,000 years [6] and 125,000 years ago.[7]
Tasmania The island is believed to have been occupied by Aboriginals for 40,000 years before British colonisation. It is thought Tasmanian Aboriginals were separated from the mainland Aboriginal groups about 10,000 years ago when the sea rose to form Bass Strait.[17] The Aboriginal population was estimated to have been between 3,000 and 7,000 at the time of colonisation, but was almost wiped out within 30 years by a combination of violent guerrilla conflict with settlers known as the "Black War", intertribal conflict, and from the late 1820s, the spread of infectious diseases to which they had no immunity. The conflict, which peaked between 1825 and 1831 and led to more than three years of martial law, cost the lives of almost 1100 Aboriginals and settlers. The near-destruction of Tasmania's Aboriginal population has been described by some historians as an act of genocide by the British.
