Indigenous Australians
British colonisation of Australia began with the arrival of the First Fleet in Botany Bay, New South Wales, in 1788. Settlements were subsequently established in Tasmania (1803), Victoria (1803), Queensland (1824), the Northern Territory (1824), Western Australia (1826), and South Australia (1836). Australia was the exception to British imperial colonization practices, in that no treaty was drawn up setting out terms of agreement between the settlers and native proprietors, as was the case in North America, and New Zealand. Many of the men on the First Fleet had had military experience among Indian tribes in North America, and tended to attribute to the aborigines alien and misleading systems or concepts like chieftainship and tribe with which they had become acquainted in the northern hemisphere.
Tasmania
After hostilities between settlers and Aboriginals ceased in 1832, almost all of the remnants of the indigenous population were persuaded or forced by government agent George Augustus Robinson to move to Flinders Island. Many quickly succumbed to infectious diseases to which they had no immunity, reducing the population further. Of those removed from Tasmania, the last to die was Truganini, in 1876. The near-destruction of Tasmania's Aboriginal population has been described as an act of genocide by historians including Robert Hughes, James Boyce, Lyndall Ryan and Tom Lawson. Boyce has claimed that the April 1828 "Proclamation Separating the Aborigines from the White Inhabitants" sanctioned force against Aboriginals "for no other reason than that they were Aboriginal" and described the decision to remove all Tasmanian Aborigines after 1832—by which time they had given up their fight against white colonists—as an extreme policy position. He concluded: "The colonial government from 1832 to 1838 ethnically cleansed the western half of Van Diemen's Land and then callously left the exiled people to their fate."
