The South Australian Housing Trust (SAHT) is an independent statutory authority originally established by the Government of South Australia responsible for providing low-cost rental housing to working people and their families, as a means of supporting industrial development in the state prior to World War II. Following the end of the war its role expanded to become a large-scale developer and public housing authority, but since the 1980s this has been curtailed. From the early 2000s to 1 July 2018 SAHT Services were administered through Housing SA, a division within the Department for Human Services. From 1 July 2018 Housing SA and Renewal SA were merged into the South Australian Housing Authority.
