Fish Rock at South West Rocks
Australia's best ocean cave dive, and voted among the top dive sites in Australia, Fish Rock is situated just two kilometres from Smoky Cape at the South West Rocks on the New South Wales. The thrill of entering a 125 metre (410 ft.) long cave and moving right through the centre of a small island is a dive not to be missed. As well as the cave itself, Fish Rock is home to a large array of marine life, hence how the island came to be named. Importantly both Fish Rock and Green Island are critical habitat areas for Grey Nurse sharks that live here in large numbers all year. Created by a fault in the island, Fish Rock Cave runs from the deeper seaward entrance at 24 metres (78 ft.), 125 metres (410 ft.) through the rock emerging into the fish-filled, silhouetted shallower entrance fringed by gorgonian corals (pink) at 12 metres (39 ft.). Fish Rock has a completely unique ecosystem. The temperature inside the cave is one degree warmer than the surrounding ocean and the water always clear. A regular strong current brings the nutrients to the area attracting the fish life. It is easy to plan your dive to minimize or take advantage of the current (drift dive).
