British arriving at Australia

In 1770 the british declared Australia no-mans land, even though there were inhabitants. 16 years later they made it a british colony. In these years the prisons were overflowing with prisoners, and the british decided to send all these convicts to Australia. As the colony grew, the Aboriginals began to get pushed away, and during the years afterwards, they killed many Aboriginals with poison in their waterholes and guns. Furthermore they arranged their breeding programs, where they tried to breed the aboriginal genes out of Australia.
