Aboriginal Tasmanians
The Aboriginal Tasmanians (Palawa kani: Palawa or Pakana) are the Aboriginal people of the Australian island of Tasmania, located south of the mainland. For much of the 20th century, the Tasmanian Aboriginal people were widely, and erroneously, thought of as being an extinct cultural and ethnic group that had been intentionally exterminated by white settlers. Contemporary figures (2016) for the number of people of Tasmanian Aboriginal descent vary according to the criteria used to determine this identity, ranging from 6,000 to over 23,000. First arriving in Tasmania (then a peninsula of Australia) around 40,000 years ago, the ancestors of the Aboriginal Tasmanians were cut off from the Australian mainland by rising sea levels c. 6000 BC. They were entirely isolated from the outside world for 8,000 years until European contact. Before British colonisation of Tasmania in 1803, there were an estimated 3,000–15,000 Palawa. The Palawa population suffered a drastic drop in numbers within three decades, so that by 1835 only some 400 full-blooded Tasmanian Aboriginal people survived, most of this remnant being incarcerated in camps where all but 47 died within the following 12 years. No consensus exists as to the cause, over which a major controversy arose. The traditional view, still affirmed, held that this dramatic demographic collapse was the result of the impact of introduced diseases, rather than the consequence of policy. Geoffrey Blainey, for example, wrote that by 1830 in Tasmania: "Disease had killed most of them but warfare and private violence had also been devastating." Henry Reynolds attributed the depletion to losses in the Black War. Keith Windschuttle claimed that in addition to disease, the prostitution of women in a society already in decline, explained the extinction. Many historians of colonialism and genocide, such as Ben Kiernan, Colin Tatz, and Benjamin Madley, consider that the Tasmanian decimation qualifies as genocide by the definition of Raphael Lemkin adopted in the UN Genocide Convention.
