Sudburry East Wall is a wall and reef dive off Queensland that suits beginners well, with no current and visibility reaching 15 to 30 metres in the clearer conditions. The wall drops from around 5 metres down into deeper water at 30 metres, so you can stay shallow and comfortable while still exploring interesting terrain. Keep an eye out for clownfish tucked into anemones, nudibranchs along the reef surface, and feather stars anchored to the coral. Giant clams sit on the reef, and sea turtles pass through regularly. Reef sharks and barracuda are also spotted here, though they typically keep their distance. Access is by boat charter, with guided tours available.
