Diver's Notes

Previous dive to this on same day had virtually no visibility at all & so by comparison this dive was ok. Very murky & lost of water particles. Made photography very difficult. But there was some more interesting sea life & starting with breeching humpback whales seen from the boat.

Dove west from the anchor line following the verge between rocks and sand line. Old Mans Hat has fantastic sponge gardens and soft corals. Returned east back to anchor line for surface.
Port Jackson shark
Black reef leather jackets in numerous pairs
Blue grouper
Pigmy rock cod and red rock cod
Red morwong

*multi level dive - did not exceed NDL
