The Geographical Names Advisory Committee advised in 2001 that the extent of the peninsula is:[3]
that portion of land between Gulf St. Vincent and the Southern Ocean (sic), a line from Aldinga (sic) (southern end of Aldinga Bay) to Middleton (eastern end) being the cut-off for the peninsula. This boundary has not to be gazetted at present, and is intended to be the extent of the geographic feature only and is not to be applied to any industry or interest group regional identification.
Towns of interest in the area include Victor Harbor, Willunga, Mount Compass, Normanville, Goolwa, Yankalilla and Rapid Bay. Districts include Inman Valley and Hindmarsh Valley. A ferry travels between Cape Jervis, at the tip of the peninsula, and Kangaroo Island. There is surfing on both the west and south facing coasts - known locally to Adelaide surfers as the Mid South Coast and the Far South Coast. Surf spots of note include Waitpinga and Middleton on the Far South Coast.
Only places with the name still in use in either the original or anglicised version are listed above. Many names have been anglicised; for these the original French name appears in brackets.
