Surrounded by sprawling rocky reef inhabited by weedy seadragons, giant cuttlefish, blue devilfish, fiddler rays and grey nurse sharks, most of Broughton’s sites are great for new divers – easily accessible, relatively shallow, with no current. Grey nurse sharks are the major draw and occur here year round, though peak season is February to June. The sharks can be encountered regularly at sites like Looking Glass, Shark Gutter, East Head and North Rock. Highlights include the sharks amongst the shape-shifting schools of yellow-tail scad off North Rock, and the spectacular topography of the amphitheatre-like Looking Glass. When a day of diving is combined with topside encounters with migrating humpback whales and pods of common dolphins, a visit to this island is a must.
