Tasman Peninsula & Eaglehawk Neck · Tasmania
Scuba Diving at Waterfall Bay
Dolerite walls, sea caves and giant kelp beneath some of Australia's highest sea cliffs.


Waterfall Bay sits beneath towering dolerite cliffs on the Tasman Peninsula, and the columnar rock continues underwater as sheer walls and cave systems.
Sponge gardens cover the walls in dense colour, and giant kelp grows in the shallower areas where it remains.
The bay holds several distinct sites including caves and arches, and access depends entirely on swell conditions.
Recommended: Open Water Diver. Parts of the site reach 35 m, which needs Deep specialty and recent deep experience. What can I dive with my cert?
