Yamato Maru: A 4395 ton cargo carrier sunk on 18 April 1943.
Truck bodies are still visible.
The Lighthouse: A huge, coral bommie 6-7 metres tall with swim- throughs, giant sponges, sea whips and schools of reef fish.
Reimers Wall: Over-hangs, swim-throughs and canyons around the open side of the reef. The drop-off plummets to 50m before easing away.
Submarine Base: A sheer drop-off (250m plus) close to shore. The natural, sheer wall covered in soft corals is the edge of a vast caldera. Barrel sponges, sea-fans and whips decorate the wall.
