Before British colonisation of South Australia, the Kaurna people occupied the land from the Adelaide plains and southwards down western side of the Fleurieu Peninsula. There was a camp at Aldinga known as Camp Coortandillah, and Kaurna people were present living in the Aldinga Scrub until the 1870s, when Bishop Augustus Short sent the remaining people to the mission at Poonindie, thus ending their occupation of the area. After they were removed, some Aboriginal people from the Goolwa area (Ngarrindjeri people) occupied the area. The Kaurna language name of Aldinga was Ngaltingga.
