Meet the site

Cape Banks Bridge is a mixed reef a few hundred metres north of the tip of Cape Banks, close to the low rock spit that joins the cape to the mainland. It has a small place in Sydney diving folklore: it was found on Christmas Eve 2000 by divers chasing a DIVE Log article that claimed a cave full of grey nurse sharks lay off here. There is no cave and there were no sharks – McFadyen later established the story had been fabricated to influence charter operations – but the divers who went looking found a good reef anyway. From the boat the sounder shows a sandy bottom at 27–28 m with scattered rocks, then a flat kelp-covered reef between there and 22 m, and in shallower water a vertical wall at 15 m that rises to clear rock at 10 m full of nooks and crannies. Sponges and small gorgonians cover the wall and the rock faces. Fish life is excellent: eastern blue devilfish in the holes, one-spot pullers, seapike, bream and leatherjackets over the reef, and rays on the sand including a huge bull ray. It is a comfortable intermediate boat dive with a natural profile from the deep sand up to the 10 m wall, easily covered on scooters over 100 m in each direction, and it is diveable on the flood tide when the bay's outflow would spoil sites nearer the heads. Like everything on this cliff line it is a private-boat and club site with no charter service, fifteen to twenty minutes from the Botany Bay ramps, and it pairs well with the Cape Banks Caverns or the Minmi Trench on a two-dive morning.

Topics flagged by the stored research

These are questions prompted by the existing notes, not a verified or complete hazard assessment.

Lines and obstructions
Discuss any known entanglement concerns and the suitability of the planned area.
Water movement
Ask how swell and local exposure affect the proposed entry, exit and route.

Historical access notes exist for this record, but have not been independently verified for current use. Request current directions from the operator or site manager rather than following an old entry description.
