Description: The craggy island of Fish Rock is no indication of the splendor that lies underneath. At 120 metres long, and well known as one of the largest ocean caverns in the southern hemisphere, FISH ROCK CAVE has attracted divers worldwide. Enter the deep end of the cave at a depth of 24 metres where thousands of bullseyes hang suspended. Swim into the tunnel entrance over huge wobbegong sharks and a large bull ray resting on the bottom. You’ll pass by clusters of live cowry shells, a large Spanish dancer, bryozoan lace coral and sea cucumbers to name but a few.

Ascend up one of the two vertical chimneys with only your torch light piercing the darkness, and see the many glowing eyes from hundreds of painted crayfish following your progress. At the right time of year, giant cuttlefish lay their eggs in the cave and the huge male is a spectacular sight with his colours flashing. Pop up into the bubble cave for a quick chat before emerging into the light zone.

The shallow end usually stops people in their tracks. The deep blue opening is a vision people have seen in many photographs, magazines and books and it still doesn’t prepare them for the spectacular beauty. Silhouetted in the opening are thousands of bullseyes, gorgonian coral fans, trumpetfish, black cod and many other species of fish. During the months of April through to November, the occasional grey nurse shark is also silhouetted in the opening making it a photographers paradise. There are also nudibranchs, bright orange zooanthids, moray eels and anemone and clown fish....and all this before emerging.
