Cocklebiddy Cave - Australia

Cocklebiddy Cave is a boat accessible salt water dive site, located in Australia. The maximum depth is 61-70ft/19-21m. The average visibility is 26-30ft/8-9m.

The longest submerged cave passage in the world is one for expert divers only. Underground the Nullarbor Plain is a 300-meter chamber reaching onto a 180-meter lake and a series of dry rock chambers laid out in an eight-kilometer long honeycomb pattern. It’s believed that less that 100 people have ever entered this cave, so there’s a strong possibility you’ll be the first to discover something new in its dark, eerie corridors.

10 kilometers north of Cocklebiddy Roadhouse; to dive you must obtain permission from Western Australia’s Conservation and Land Management (CALM).
