New South Wales
Diving in Port Stephens
Port Stephens has two personalities. Inside the port, Fly Point and Halifax Park at Nelson Bay are world-class shore dives on the slack tide, with sponge gardens, frogfish, seahorses and huge schools of fish under a shipping channel. Outside, Broughton Island and Cabbage Tree Island have grey nurse shark gutters, caves and seals.

THE LOCAL PLANNING BRIEF
Understand the options around Port Stephens
New South Wales offers a long sequence of coastal regions rather than one central dive gateway. Our directory separates Sydney areas, the north and mid-north coast, and the south coast so that you can compare a realistic local base. A Sydney stay and a Jervis Bay or Coffs Harbour trip need different transport and departure arrangements; do not treat a state-level search as a list of nearby sites.
What this regional directory records Counts describe published records, not bookable trips or confirmed open sites.
There are 22 published site records in Port Stephens. The recorded categories include reef (6), shore/rock platform (6), island (4), cave/cavern (2). These categories reflect the database; they are not a ranking, a conditions report or an assessment of your suitability.
Use the Port Stephens 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 Port Stephens?
Begin with the individual site and its source notes, then discuss the proposed trip with a local provider. The 22 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 Port Stephens 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.
