About this site
Cathedral Cave sits in Waterfall Bay on the Tasman Peninsula in Tasmania and is the largest sea cave system in Australia. It is known for its expansive caverns, intricate tunnels and impressive entrances, and visibility here is excellent.
Just out from the shore, the dive passes through forests of giant kelp. The temperate water holds sea dragons and draughtboard sharks, and a seal turns up now and then.
