This temperate reef is renowned among divers for its dramatic underwater topography—a sheer wall of rock encrusted with colourful sponge gardens and kelp—and its rich marine life including giant cuttlefish, wrasse, and schools of Australian salmon. Accessible only by boat due to its offshore position, the reef offers a wild, exposed diving and snorkelling experience on calm days.
