Neptune Islands - South Australia

Diving the Neptune Islands is all about one thing: great white sharks. This isn't your typical coral reef dive, but if getting in the water with apex predators sounds like your kind of adventure, then it’s an experience you’ll remember. We're talking cage diving here, either at the surface or dropped to the seafloor, putting you face-to-face with these powerful creatures. It’s cold water, nutrient-rich stuff, so expect impressive, sometimes dramatic, encounters rather than colourful fish. Definitely not for everyone, but if you’re curious about great whites, this is where you come to see them in Australia.
