Retta Long was resident missionary to the La Perouse Aboriginal Settlement before establishing the Aborigines Inland Mission of Australia. The mission was inter-denominational. Retta Long launched a monthly magazine for the mission, Our AIM. A number of AIM auxiliaries were set up around the country, and by the 1930s the mission claimed to be preaching to 11,000 Aborigines.
