StandoutRich in charismatic marine life

Triangle Reef in Australia's Coral Sea offers a classic outer reef dive. We've seen a good mix of pelagic action here, with reef sharks often cruising the wall and the occasional manta ray gliding past. It's a spot for experienced divers comfortable with potential currents and open ocean exposure, not really a beginner's site. Expect healthy hard corals and plenty of schooling fish.
