    StandoutExceptional marine biodiversity

    Hazelgrove Reefs delivers a solid Great Barrier Reef experience, reliable for a relaxed dive. We’ve found decent patches of hard corals here, interspersed with sandy channels, and it’s a good spot for seeing the usual reef suspects – parrotfish, wrasse, and small reef sharks cruising by. It’s a comfortable dive for anyone looking for a straightforward exploration without strong currents, suiting newer divers well. Visibility typically hovers around the 15-20 meter mark.

    Safety Notes

    Strong currents typical this month (avg 30 cm/s). Good buoyancy control essential.
