Western Australia
Diving in Perth
Perth's metropolitan coast from Rockingham to Mindarie has limestone reef ledges, caves and swim-throughs in 5–20 m, the wreck trails at Rockingham and Coogee (Omeo, the Saxon Ranger, the Kwinana Grain Jetty), the Blackwall Reach river dive, and dozens of easy shore entries. Tropical fish arrive on the Leeuwin Current each summer to join the temperate regulars.

THE LOCAL PLANNING BRIEF
Understand the options around Perth
What this regional directory records Counts describe published records, not bookable trips or confirmed open sites.
There are 82 published site records in Perth. The recorded categories include reef (24), wreck (24), shore/rock platform (15), jetty/pier (7). These categories reflect the database; they are not a ranking, a conditions report or an assessment of your suitability.
Use the Perth 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 Perth?
Begin with the individual site and its source notes, then discuss the proposed trip with a local provider. The 82 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 Perth 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.
