About this site

Carnac Island sits off the coast of Western Australia near Fremantle, in the waters of Cockburn Sound. The site has a maximum depth of around 3 metres and is considered a beginner dive, well suited to shallow, sheltered exploration. Divers have reported blue-ringed octopus and tidal current as hazards worth watching for, and the same reports describe an unusually varied mix of marine life for such shallow water, including cuttlefish, wobbegong and nurse sharks, leopard or zebra sharks, seahorses, sea turtles, octopus, nudibranchs, parrotfish, humphead wrasse and bumphead parrotfish.
