StandoutRich in charismatic marine life

Knuckle Reef, out in the Coral Sea, is a solid choice for divers looking for a classic Australian coral reef experience. We’ve found good numbers of reef sharks cruising the perimeter and plenty of pelagic action off the deeper walls. It’s a great spot if you’re comfortable with open ocean diving and want a taste of what the Coral Sea is really about.
