CharacterReef dive

StandoutRich in charismatic marine life

One Fathom Patch sits in the Coral Sea, an exposed reef often delivering some serious current. Expect to drift past walls covered in gorgonians and whip corals, with good chances of spotting grey reef sharks patrolling the drop-off. This site is definitely one for experienced divers comfortable in stronger flows and open water. We'd suggest it for those looking for pelagic action rather than macro critters.
