    StandoutExceptional marine biodiversity

    Flynn Reef is a solid coral reef dive on the Outer Great Barrier Reef, a good pick for newer divers or those looking for an easier day. You'll find plenty of clownfish darting through anemones, a few reef sharks patrolling the edges, and schools of fusiliers hanging over the bommies. It’s a comfortable dive, often with good visibility and minimal current, making it a reliable choice for a relaxing couple of dives.

    Safety Notes

    Strong currents typical this month (avg 30 cm/s). Good buoyancy control essential.
