Dive-site story
Located south of Adelaide in the Port Noarlunga Aquatic Reserve, this site centers on a prominent jetty leading out to an offshore limestone reef system. Divers descend directly from stairs at the end of the jetty into sheltered waters between the pier and the reef wall. The underwater trail features signposts highlighting local marine habitats, while the outer reef drop-off hosts caves, ledges, and swim-throughs exposed to open gulf waters.
Extensive limestone reef formation protected within an established aquatic reserve
Purpose-built diver stairs at the end of the jetty for straightforward water entries
Regular encounters with southern temperate species including Port Jackson sharks and southern blue devils
Underwater interpretive trail with marked points of interest across the reef
Location
Use the map to plan with your operator and confirm the exact entry point on the day.
Seasonality
Late spring through autumn brings warmer waters and more consistent offshore breezes that favor clear visibility.
