Best for intermediate divers, 5-40m, boat entry, moderate current.
Crystal Plateau is a remote offshore reef in Queensland, Australia, featuring a shallow reef top at 5 metres that transitions into a wall and drop-off reaching 40 metres. The site is defined by high visibility, typically ranging from 30 to 60 metres. Divers encounter a variety of reef fish and invertebrates across the plateau and wall face, which are covered in soft corals, sea fans, and plate coral. Currents are generally moderate but can strengthen due to the site's exposure to the open ocean. Boat access is required, and the site is suited for intermediate divers comfortable with deep walls and potential currents.

Position yourself on the up-current side of the plateau early in the dive so you can drift along the wall rather than fight back to the boat. Keep a close eye on your depth gauge once you reach the drop-off edge, as the wall pulls you down quickly in those conditions.
The site is located on the remote Bougainville Reef in the Coral Sea, approximately 230 km northeast of Cairns. Access is only possible via multi-day liveaboard dive vessels departing from ports like Cairns.
