Slowly shelving beaches. The north cove is very gradually sloping sand near the beach, but gets rocky near the mouth, where the depth gets down to about 3 to 4m. In this area there are lots of small boulders which provide shelter for a variety of invertebrates and fish. At the mouth it gets deeper quite suddenly over a rocky ledge, and drops down to sand bottom which continues all the way north to Photographer’s Reef and beyond. There are a number of pinnacles in the area to the north east and east of the north cove. The south cove inirially slopes more steeply and remains mostly sand bottom. It flattens out soon and is bordered by rock on both sides.
