Aldinga, SA
By Lauren McCaleb · Reviewed by Dylan Duncan ·
Aldinga is a town on the southern fringe of Adelaide in South Australia, about 45 kilometres south of the city in the City of Onkaparinga, a little inland from Aldinga Beach and the dunes of the Aldinga Scrub. The area is Kaurna country, known in the Kaurna language as Ngaltingga, and Ngarrindjeri people from the Goolwa district were also associated with the region. Aldinga was laid out as a farming town in 1857, its plan credited to a local farmer, Lewis Fidge, and it grew as a stop on the old coach road south, now the Main South Road. Today it sits at the southern edge of the McLaren Vale wine district.
