Diving in Ashmore Reef
Ashmore Reef is a marine park 320 km off the Kimberley coast, closer to Indonesia than to any Australian town, with seagrass, sand cays and a reef that supports dugongs, turtles and one of the highest densities of sea snakes recorded anywhere. It is visited by research vessels and very occasional expedition charters.

Record your trip questions →Questions, answered
How do I choose a dive in Ashmore Reef?
Begin with the individual site and its source notes, then discuss the proposed trip with a local provider. The 1 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 Ashmore Reef 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.
