    StandoutExceptional marine biodiversity

    Middle Reef offers a classic GBR dive. We found good coral coverage, mostly hard corals forming a vibrant landscape. It's a comfortable drift when the currents are running, and you'll often see several reef sharks patrolling the deeper sections. This site is a solid pick for divers looking for a reliable, easygoing reef dive without too much fuss.
