    Mackerel Bay offers solid diving in the Coral Sea, particularly if you appreciate a good swim-through. We found healthy populations of reef sharks here, often patrolling the deeper sections. It’s a site that suits divers looking for a relaxing profile with the chance to spot larger pelagics moving through.
