Tasmanian Aborigines were exiled on Flinders Island after 7 years of war under a treaty negotiated by George Robinson. Powerful evangelical forces sought to lead Aborigines to Christ and restore rights. By 1830 Humanitarians and Missionaries began to take up the anti-slavery campaign with the official message to Australia that Aboriginals had legal rights as subjects of the crown. However the new mood did not go down well on the Frontier and horrific massacres took place.
