Convict era of Western Australia

The convict era of Western Australia was the period during which Western Australia was a penal colony of the British Empire. Although it received small numbers of juvenile offenders from 1842, it was not formally constituted as a penal colony until 1849. Between 1850 and 1868, 9,721 convicts were transported to Western Australia on 43 convict ship voyages. Transportation ceased in 1868, and it was many years until the colony ceased to have any convicts in its care.

The first convicts to arrive in what is now Western Australia were convicts of the New South Wales penal system, sent to King George Sound in 1826 to help establish a settlement there. At that time, the western third of Australia was unclaimed land known as New Holland. Fears that France would lay claim to the land prompted the Governor of New South Wales, Ralph Darling, to send Major Edmund Lockyer, with troops and 23 convicts, to establish the King George Sound settlement. Lockyer's party arrived on 25 December 1826. A convict presence was maintained at the settlement for nearly four years. In November 1830, control of the settlement was transferred to the Swan River Colony, and the troops and convicts withdrew.

In December 1828, the British Colonial Office agreed to establish a colony at Swan River in Western Australia. It then issued a circular outlining the conditions of settlement, which stated, "It is not intended that any convicts or other description of Prisoners, be sent to this new settlement." That Swan River Colony would not be a penal colony was highly attractive to many of the potential settlers, and the condition was mentioned often by promoters during the period of Swan River mania.
