South Australia is the only Australian state to have never received British convicts. Another free settlement, Swan River colony was established in 1829 but Western Australia later sought convict labour, and in 1849 Western Australia was formally constituted as a penal colony. Although South Australia was constituted such that convicts could never be transported to the Province, some emancipated or escaped convicts or expirees made their own way there, both prior to 1836, or later, and may have constituted 1–2% of the early population.
