The Aldinga Conservation Park is located on the Fleurieu Peninsula some 46 km south of Adelaide and lies between the coastal townships of Aldinga Beach in the north and Sellicks Beach to the south.

The Aldinga Scrub is one of the few remaining patches of native vegetation characterising the pre-settlement coastal scrubland in the vicinity of what is now greater Adelaide. It is of rare significance and is noted for its unusual association of plants including species characteristic of sclerophyll forest, mallee scrub and coastal sands.

In January 2022, the Aldinga Conservation Park was proclaimed.  The new park incorporates Aldinga Scrub with the Aldinga Washpool Lagoon. Since 2001, the Washpool has been recognised as a nationally important wetland and recorded in the Commonwealth Government's Directory of Important Wetlands in Australia.
