Sydney Hadley established Sunday Island Mission as a private mission in 1899. It was run by the Australian Aborigines' Mission (1923-1929) and the United Aborigines Mission from 1929 to 1934 when it relocated to Wotjulum (1934-1937) before returning to Sunday Island. From 1905, children at Sunday Island were under the guardianship of the departments responsible for Aboriginal welfare.
