The Limestone Coast zone is located in the south-east of South Australia bounded by the continental coastline to the south, the border with the neighbouring state of Victoria to the east and the Lower Murray wine zone to the north. The wine zone is the land south of a line located at appropriately 36 degrees 50 minutes south, i.e. in line with Cape Willoughby at the east end of Kangaroo Island. The term ‘Limestone Coast’ was registered as an AGI under the Wine Australia Corporation Act 1980 on 27 December 1996.
