The Pipeline is a muck diving site that rewards patient, detail-oriented divers willing to work through variable visibility. Depths run from 16 to 72 metres, putting the deeper sections firmly in technical diving territory, though the most productive hunting grounds sit in the mid-range. Visibility swings between 5 and 30 metres depending on conditions. The artificial reef structure and surrounding seagrass draw an impressive cast of cryptic species: White's seahorse, ornate ghost pipefish, pyjama squid, decorator crabs, and blue-ringed octopus all turn up regularly. Wobbegong sharks and moray eels occupy the reef structure, while cuttlefish and nudibranchs reward slow, methodical searching.

Deploy your SMB early and monitor it throughout the dive as boat traffic here is serious and unforgiving. Time your entry for the slack period between tidal movements to get the best of the visibility and avoid the site's stronger current surges.
Park at the public car park at d'Albora Marina, near the breakwall. Gear up and walk along the concrete path past the fish co-op building to a set of rock steps that provide entry to the water.
The primary hazard is the strong tidal current; dive only at slack high tide. There is frequent boat traffic overhead; divers must not surface away from the shoreline. The venomous blue-lined octopus is regularly sighted. Sharp oysters can be present at the entry point.
