South West Rocks 24-26 October 2025

Fish Rock Cave, the only true ocean cave dive in Australia running 125 metres right through Fish Rock which lies two kilometres south-east of Smoky Cape – South West Rocks. Fish Rock is home to a completely unique ecosystem. The temperature inside the cave is always at least one degree warmer than the surrounding ocean and the water is always clear. The shallow entrance of Fish Rock Cave at a depth of 12 metres is a large naturally lit cavern fringed by pink gorgonian corals and teeming with enough life to fill an entire dive. You can even go up into the bubble cave and talk to your dive buddy while being five metres underwater! The deep entrance of Fish Rock Cave is at a depth of 24 metres. You can also to see resident black cod, large wobbegong sharks, black rays and giant cuttle fish before ascending up one of the two chimneys into the main section of the cave.

Grey Nurse Sharks can be seen at Fish Rock all year round, in recent years there have only been a few, and some days no Grey Nurse sharks between February and April. However during this period there has been an increasing number of Leopard Sharks! The largest numbers of Grey Nurse Sharks can be seen during the cooler months,

May to September. From October to December, the Grey Nurse sharks usually rest in the shallow entrance of the cave, which is an awesome diving moment for even the most experienced diver! This also presents an unparalleled photographic opportunity for novice and experienced photographers. We have GoPro cameras for hire upon request. Around the island the depth varies on average between 15 and 30 metres and deep gutters form perfect aggregation areas for the sharks and other marine creatures who reside here. The western fringe of Fish Rock is washed by the currents that bring the diverse range of marine life to the area and you can expect to see lots of fish, turtles, moray eels and friendly blue groper. The eastern side of Fish Rock is spectacular. Sheer walls plunge to an average depth of 30 metres in an area that is rarely affected by current. Boulders the size of small houses line the sea floor and are home to large wobbegong sharks disguised amongst clouds of bullseyes. On the northern side of Fish Rock a pinnacle rises 30 metres from the sea floor to within 7 metres of the surface. This is one of the best dives at Fish Rock and is home to turtles, Grey Nurse Sharks, Giant Queensland Groper and a huge variety of fish life.
