Diving in Cocos (Keeling) Islands
Cocos is a true coral atoll 2,750 km north-west of Perth, with 27 islands around a shallow turquoise lagoon and an outer reef that drops to deep water. Manta rays feed in the channels, green turtles are everywhere, dolphins visit the boats, and the outer walls hold grey reef sharks, tuna and huge schools of fusiliers. Two sites, the Cabbage Patch and the Rip, are among the best drift dives in the Indian Ocean.

How do I choose a dive in Cocos (Keeling) Islands?
Begin with the individual site and its source notes, then discuss the proposed trip with a local provider. The 36 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 Cocos (Keeling) Islands 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.
