Aldinga Bay

Aldinga Bay lies between Snapper Point in the suburb of Aldinga Beach at its northern extremity and the remains of Myponga Jetty at Myponga Beach at its southern extremity. ==Ports and other settlements==

The following settlements are located along its coastline from north to south: Aldinga Beach and Sellicks Beach in the City of Onkaparinga and Myponga Beach in the District Council of Yankalilla. ==Protected areas==

The waters of Aldinga Bay are within the Encounter Marine Park. The south-eastern part of the Aldinga Reef aquatic reserve is within the bay. ==Notes==
