The Split

Jibbon Head, Royal National Park, New South Wales, Australia

Sydney's best-rated boat dive by McFadyen: a kelp-topped reef south of Port Hacking that drops vertically to sand at about 26-28 m, cut near its base by a 70 m+ north-south crack about 4 m deep and 2 m wide with side cracks, swim-throughs and caves. Visibility often 15-20 m, up to 35 m. Depth 20 to 28 m.
