Transportation of convicts eventually brought a total of about 160,000 prisoners to Australia. The initial character of a penal colony lasted for about 60 years in the areas of major original settlement. It ended in 1840 in New South Wales and in 1852 in Van Diemen’s Land (modern Tasmania), which became a colony in 1825. Western Australia, which was founded in 1830 by free immigrants, added convicts to its population by its own choice from 1850 to 1868. Convicts were not sent to South Australia, which became a colony in 1836.
