Best for intermediate divers, shore entry, mild current.
The Lagoon on Kangaroo Island is a sheltered shore dive protected from the Southern Ocean by a reef ledge. This site offers calm, shallow waters suitable for intermediate divers. Entry is directly from the shore, where parking is available. Divers should exercise caution around the reef, as the coral edges are sharp and can cause injury upon contact. Water temperatures range from 15C to 18C, and a 7mm wetsuit or drysuit is recommended for comfort. While conditions are generally manageable with mild currents, visibility can be variable. Divers are advised to plan their dives for the morning when the water is typically at its calmest.

The lagoon is located within Coffin Bay National Park. Access is via a boardwalk from the Golden Island carpark, followed by a walk of approximately 200 metres along the beach around a point. The lagoon is on the right (westerly direction) and is best accessed at low tide.
