The Gap is a South Australian reef dive accessed by boat, where moderate current and surge keep conditions honest and the site reserved for experienced divers. Working depths run to 15 metres, and visibility is variable, so be prepared to adapt your plan on the day. The reef holds a solid cast of temperate species: blue devils and blue groper are the standout residents, while sweep move in schools through the water column. Keep an eye on the ledges and crevices for crayfish and nannygai tucked into the structure. Current management and surge awareness are non-negotiable here.
