Cocos (Keeling) Islands Marine Park
An Australian marine park declared in 2022 over the ocean around the atolls.
Updated 3 September 2026
The Cocos (Keeling) Islands Marine Park was declared in 2022 and covers the ocean around both atolls out to the edge of Australian waters, a very large area of deep sea, seamount and reef with two small atolls in the middle of it. Most of it nobody ever sees. What visitors encounter is the reef around the lagoon and the drop-offs on the ocean side, worked by a handful of dive operators.
The landscape
- The reef edge - the drop-offs on the ocean side of the atoll.
- The lagoon reef - the coral inside the ring the operators work.
- The 2022 declaration - the park established over the surrounding ocean.
- The scale - protection running far beyond the visible atolls.
When to go
April to October is drier with steadier conditions for diving. Visibility is generally good year round. The wet season brings heavier weather.
What to expect
Almost all of the park is deep ocean nobody can reach. Dive operators are few and must be booked ahead. Zoning rules govern where fishing is allowed and should be checked before going out.
Nearby
Pulu Keeling is north, and the lagoon is at the centre.
