South Passage offers a mix of wall, reef, and cave diving in Western Australia, with depths reaching 23 metres in the deeper sections. Visibility here is variable, so conditions can change between dives, and the current runs strong, which means timing your dive with slack water is important even as a beginner. The site is known for reef-building corals and attracts dugongs, turtles, rays, sea snakes, and sharks. Because of the current and boat traffic, this site suits beginners who are comfortable in open water and always dive with a guide. Boat entry only, so plan your trip accordingly.

Plan your dive around slack tide to avoid the strongest current, and always keep an eye on your surroundings given the active boat traffic in this passage. Check locally for up-to-date conditions before heading out, as visibility can shift significantly.
Access is via boat, launched from the beach at Shelter Bay. Reaching Shelter Bay by land requires a high-clearance 4WD vehicle to traverse the tracks of Edel Land National Park.
Strong tidal currents are a primary hazard; only enter the water on slack tide and in good weather. Be aware of boat traffic transiting the passage.
