"When in Hobart in May 1853 the ship St Vincent sent ashore the last consignment of convicts, Tasmania had received almost as many convicts as New South Wales during the long history of transportation. Western Australia now remained the only penal colony and it received its last convict ship on 9 January 1868. For eighty years convicts had been shipped to Australia, and a total of 163000 had set out on that voyage from which few returned. In the modern history of Europe there was rarely a planned deportation on a more ambitious scale until the era of Stalin and Hitler."
