Best for advanced divers, 3-42m, boat entry, moderate current.
Diamond Islets features a significant wall structure in the Coral Sea, dropping from 3 metres to 42 metres. The site is characterised by moderate currents and visibility ranging from 30 to 50 metres. Divers encounter gorgonian fan corals and nudibranchs along the wall, while the open water attracts dog tooth tuna, chevron barracuda, and hammerhead sharks. Grey whaler, white tip reef, and tawny sharks are frequently observed, alongside manta rays and green turtles. Due to the presence of caves, swim-throughs, and strong currents, this site is suited for advanced divers. Boat access is required, and night diving is available.

Plan your dive around slack water where possible, as current direction can shift and sweep divers along the wall faster than anticipated at depth. May through October offers the most reliable conditions for pelagic sightings.
Access is via liveaboard charter vessels departing from Cairns. The Diamond Islets are remote and not visited on all Coral Sea itineraries, so checking with specific operators is required.
