    StandoutExceptional marine biodiversity

    Matty's Crack at Lighthouse Reef is a drift dive that often delivers some decent pelagic encounters. We've regularly seen reef sharks here, sometimes even a bull shark cruising by in the blue. Keep an eye out into the deeper water. It's a site best suited for divers comfortable with current.
