Tasmanian Aboriginals arrived 35,000 years ago and isolated 8,000 years from mainland. Pre-contact population 3,000-15,000 dropped to 400 full-blooded by 1835. Introduced diseases like influenza, pneumonia, tuberculosis, and venereal diseases caused massive deaths and infertility. Sealers abducted and enslaved dozens of Aboriginal women, skewing sex ratios and accelerating collapse. Black War killed 362 Aboriginals versus 183 settlers. George Robinson relocated survivors to Flinders Island where most died from disease and poor conditions. Last full-blooded Tasmanian died 1876. Genetic isolation from mainland increased disease susceptibility. Multiple distinct ethnic/language groups existed pre-contact. Remnant populations stranded by rising seas died out. Modern Tasmanians descend from European-sealer men and Aboriginal women. No consensus on genocide but many historians classify it as such. Venereal diseases sterilized many women. Respiratory epidemics swept tribes pre-1803 via sealers. Clan warfare intensified by settler abductions of women. Wybalenna settlement failed with 220 arrivals mostly dead in 14 years. Oyster Cove final settlement saw numbers dwindle to one by 1876.
