The Gap is a boat-access site located off Watsons Bay, offering a diverse underwater topography that includes reefs, walls, caves, and swim-throughs. Divers can explore depths ranging from 10 to 23 metres, with an average depth of 15 metres. The site is exposed to ocean swell, which can create surge, and its location at the entrance to Sydney Harbour necessitates caution regarding boat traffic. Due to the presence of overhead environments, strong currents, and variable visibility between 5 and 20 metres, this site is suitable only for advanced divers. A 5-7mm wetsuit is recommended to manage water temperatures that fluctuate between 18 and 23 degrees Celsius.
