Bougainville Reef sits in the Coral Sea off Queensland, combining wall diving, drift diving, and wreck exploration across a depth range of 5 to 40 metres. Visibility can reach 40 metres in good conditions, though it can close down considerably, so conditions dictate the dive. Variable and at times strong currents make this strictly advanced territory, and that same water movement is what keeps the reef productive with various reef species working the structure. The wall sections reward divers who push deeper, while the wreck adds a different dimension to the site. Sharp coral and boat traffic require constant situational awareness throughout.

Current direction and strength can shift with little warning at Bougainville, so brief closely with your skipper before the dive and agree on a clear drift plan and pick-up procedure. Facilities are limited, so confirm all arrangements, including gas fills and surface support, before you leave port.
