StandoutRich in charismatic marine life

Knuckle Reef South sits out in the Coral Sea, offering a raw, open-ocean dive experience. We found the coral formations impressive, with plenty of reef fish going about their business. It’s a good spot for divers looking for a more remote feel, away from the usual crowds found closer to the coast. Expect solid reef diving, not necessarily big pelagics, but a healthy ecosystem.
