Neptune Islands

The Neptunes are Australia's only licensed great white cage-diving grounds, two clusters of granite islands where long-nosed fur seals breed and the sharks that hunt them patrol. Surface cages hang off the stern on hookah air, open to anyone who can climb a ladder, while one long-running operator lowers a cage to the seabed so certified divers can watch whites cruise at their own level, unhurried and enormous. Sharks are present year-round without being guaranteed on any given day; the cooler months are often quoted for larger females. Between passes, the seals themselves supply the comedy the sharks decline to provide.
