Hedley Reef
Why dive here
With 154+ marine species recorded in the area - including hammerhead sharks, sea turtles, tiger sharks and napoleon wrasse - Hedley Reef offers some of Great Barrier Reef's richest reef diving. Water ranges 24-30°C, warmest January, February, March.
Hedley Reef offers a straightforward dive on a classic Great Barrier Reef coral system. Expect to see the usual mix of reef fish – parrotfish, angelfish, and the occasional whitetip cruising past. It's a reliable spot for divers looking for a relaxed experience without strong currents or complex navigation. We think it's a good choice for newer divers or those who just want to soak in the reef ambiance.
Safety Notes
Strong currents typical this month (avg 30 cm/s). Good buoyancy control essential.
