North Rock sits off New South Wales and draws intermediate divers primarily for its grey nurse sharks, which share the water alongside eagle rays, giant cuttlefish, and nudibranchs. Depths run from the surface to 20 metres, making it manageable for those comfortable with variable conditions. Visibility and current both shift depending on the day, so be prepared to adapt once you're in the water. Mado and striped trumpeter round out the fish life. The site is boat access only, with charters, guided tours, and a dive shop available to support your trip. Best conditions fall between November and June.

Grey nurse sharks are protected, so maintain a respectful distance and avoid cornering them near the rock structure. Booking a guided tour is worthwhile here given the variable current, as local guides will know the safest entry points and how the current is running on the day.
The site is accessible via a boat trip from Nelson Bay, which takes approximately 50 minutes to reach the Broughton Island group. Dive operators like Let's Go Adventures and Pro Dive Nelson Bay run trips to the island.
While Grey Nurse Sharks are generally docile, divers are briefed to stay close to the rocks and move in single file to avoid disturbing the sharks. The site is shared with fishermen, and some sharks have been seen with injuries from fishing lines.
