Scenes like this are one of Rapid Bay's major attractions and much easier to experience than finding Leafy Seadragons or nudibranchs.
Here in the 'T-Section' of the old jetty you can drift between the sponge encrusted tree-like pylons and look up at schools of Old Wives, Yellowtail, Bullseyes and Leatherjackets.
On a clear day like this there is no better shore dive within a couple hours drive of Adelaide.
On poor visibility days its best to just go hunting for Leafy Seadragons and Nudibranchs.
