Adele Island's south lagoon sits in shallow water between 5 and 10 metres, making the depths manageable for intermediate divers, but the strong currents here demand respect and solid buoyancy control. Visibility is variable, so conditions can shift considerably between dives. The reef supports both hard and soft corals, and the marine life roster is genuinely compelling: sea turtles, rays, and sharks are all realistic sightings, and humpback whales pass through during the season. Queenfish add a pelagic element to what is otherwise a reef dive. Crocodiles are a documented hazard in this region, so take local advice seriously before entering the water. Access is by boat only.

Plan your dive around tidal movement, as the strong current can make this site significantly harder on an incoming or outgoing tide. Visit between May and October when humpback whale activity peaks and conditions tend to be more predictable.
Adele Island is a remote offshore location approximately 100-150km from the mainland. Access is only possible via private vessel or on a scheduled expedition cruise, many of which depart from Broome.
An update from July 2025 mentioned crocodiles being sighted in the lagoon. The Kimberley region is known for saltwater crocodiles. Large tidal movements create strong currents.
