Mermaid Reef is a boat-access reef site off New South Wales where encounters with grey nurse sharks, Port Jackson sharks, and wobbegong sharks make it genuinely exciting for beginner divers. The reef runs from shallow areas down to around 30 metres, though beginners should stay in the shallower range and leave the deeper sections for more experienced divers. Visibility can reach 30 metres in ideal conditions, though 7 to 10 metres is more typical. The current runs moderate to strong, so plan your dive around slack tide. Beyond the sharks, keep an eye out for stingrays, moray eels, rock lobsters, black cod, kingfish, and trevally moving through the water.

July through October tends to bring the clearest visibility and the most reliable grey nurse shark sightings, so if you can choose your timing, aim for that window. Always ask your boat operator about current conditions on the day, as strong currents can build quickly and this site is not forgiving if you get caught out.
The site is accessible only by boat, typically departing from nearby harbours such as Crowdy Head or Laurieton/Camden Haven.
