Caves is a boat-access dive site in Queensland that lives up to its name, featuring overhead environments that reward divers comfortable with penetration-style navigation. Depths run from 12 to 24 metres in the deeper sections, and visibility regularly reaches 15 to 30 metres, making it easier to pick out moray eels tucked into ledges and giant clams on the substrate. Napoleon Maori wrasse, turtles, rays, and sharks are regular sightings, while anemonefish and oriental sweetlips tend to hold territory around the cave entrances. Moderate to strong currents require attention, and sea urchins occupy crevices throughout, so watch your buoyancy carefully inside the overhead sections.

The clearest visibility and most active marine life typically fall between June and November, so plan your trip within that window if you can. Carry a torch inside the cave sections regardless of conditions above, as the deeper recesses stay dark even on the best visibility days.
The site is located on Norman Reef on the Outer Great Barrier Reef, approximately 70km offshore from Cairns. Access is via boat charters, with many day trip and liveaboard operators available from Cairns.
As the site contains caves and swim-throughs, divers should be certified and comfortable with overhead environments. The site is known for drift diving, so divers should be prepared for currents.
