Cornwallis Reef
Why dive here
Cornwallis Reef is a reef dive where divers can encounter sea turtles and sperm whales. Water ranges 27-30°C, warmest May, June, July.
Cornwallis Reef offers a decent wall dive, dropping away into deeper water. You'll find a good spread of hard corals clinging to the wall, with schooling reef fish flitting past. It’s a solid choice for a second or third dive of the day, appealing to divers who enjoy a relaxed drift along a healthy reef. We wouldn't call it a showstopper, but it's a perfectly enjoyable dive for its simplicity.
