Fish Rock Cave is a 125-metre long tunnel running through Fish Rock, located 2000 metres off the coast of South West Rocks. This site features a complex overhead environment with depths ranging from 6 to 40 metres, averaging 22 metres. Divers and snorkellers navigate a passage that starts at 24 metres and exits at 14 metres. The site is exposed to moderate, unpredictable currents and surge, particularly near the entrances. Water temperatures inside the cave remain at least one degree warmer than the surrounding ocean. Due to the overhead environment and variable conditions, boat access via a guided charter is required for this intermediate-level site.

The site dives best on an incoming tide when the current pushes through the cave in a predictable direction and visibility holds firm. Book a guided charter rather than attempting this independently, as local knowledge of the current cycles makes a significant difference to how the dive unfolds.
The site is located 2km offshore from Smoky Cape and is accessible only by boat. Dive charters are operated by local dive shops in South West Rocks, such as South West Rocks Dive Centre and Fish Rock Dive Centre.
