Dive-site story
Fish Rock Cave cuts completely through a rocky islet off the New South Wales mid-north coast, forming an extensive underwater cavern. Divers enter at the deeper seaward opening and navigate an ascending tunnel that opens into large bubble-filled chambers before daylight guides the way to the shallow exit. Resident grey nurse sharks frequent the entrance and gutters, while pelagic predators cruise the outer drop-offs.

Location
Use the map to plan with your operator and confirm the exact entry point on the day.
Seasonality
Diving occurs year-round, with warmer water brought by the East Australian Current in summer and migrating humpback whales passing offshore during winter and spring.
