Western Australia
Diving in Pilbara & Dampier
The Dampier Archipelago and the Montebello Islands have coral reefs, WWII and pearling wrecks and turtles in warm, tidal, often turbid water. Onslow is the launch point for the Mackerel Islands and the Montebellos, where the 1950s British nuclear test sites are now a marine park with excellent, remote diving.

How do I choose a dive in Pilbara & Dampier?
Begin with the individual site and its source notes, then discuss the proposed trip with a local provider. The 31 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 Pilbara & Dampier 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.
