Swansea Bridge Pylons in Caves Beach, Australia, functions as an artificial reef structure. The site ranges from 5 to 18 metres in depth, with an average of 10 metres. This is an intermediate-level dive defined by strong tidal currents, requiring precise timing for slack water approximately 2.5 hours after the Fort Denison high tide. Outside this window, currents can reach 1 to 3 knots. Visibility typically ranges from 4 to 10 metres. Divers must be aware of frequent boat traffic, surf, and potential entanglement hazards from debris. A surface marker buoy is mandatory for all divers due to the active channel environment.

Slack water here is short and unforgiving, so check tide tables carefully and have your entry and exit planned before you hit the water. A surface marker buoy is mandatory, not optional, given the volume of boat traffic moving through the channel.
Entry is from the public boat ramp on the southern side of the channel, just west of the Swansea Bridge on Belmont Street. The local dive shop, Dive Swansea, is located directly across the road.
