New South Wales
Diving in Sydney Harbour
Sydney Harbour has more marine species than the entire Mediterranean, and most of its dive sites are gentle shore dives inside the heads. Clifton Gardens (Chowder Bay) is the city's night-dive institution, with seahorses, pygmy pipehorses, frogfish and octopus under the wharf; Camp Cove, Fairlight and the Fairy Bower reef are easy day dives, and North Head's outside reefs are for experienced divers on calm days.

What this regional directory records Counts describe published records, not bookable trips or confirmed open sites.
There are 33 published site records in Sydney Harbour. The recorded categories include shore/rock platform (21), wreck (6), jetty/pier (3), cave/cavern (1). These categories reflect the database; they are not a ranking, a conditions report or an assessment of your suitability.
Use the Sydney Harbour site cards to compare recorded access and depth, then open the individual pages for the map accuracy and source notes. Sites grouped in a region are not necessarily close enough to combine in one day.

Record your trip questions →Questions, answered
How do I choose a dive in Sydney Harbour?
Begin with the individual site and its source notes, then discuss the proposed trip with a local provider. The 33 published records are research options, not a list of trips available today. Match the plan to your training, recent experience and the operator’s current requirements.
When should I visit Sydney Harbour for diving?
Choose dates with a provider who runs the activity you want, then discuss seasonal patterns, recent conditions and alternative itineraries. A generic best-month claim cannot establish the conditions at your exact site or guarantee a wildlife encounter.
Can I use these maps to enter or navigate a dive site?
No. Recorded and approximate map positions support orientation only. Confirm the exact access, permissions, meeting point and route with the responsible local provider or manager.
