In the case of the McLaren Vale wine region, a character protection district with the name "McLaren Vale District" was created within the boundaries of the City of Onkaparinga. The character protection district overlays a majority of the land within the local government area. Specifically, this is land not zoned for residential and other urban uses and consists mainly of the eastern side of the local government area extending from the Sturt Creek in the north to parts of the coastal suburbs of Aldinga, Aldinga Beach, Maslin Beach, Port Willunga and Sellicks Beach in the south.
