Cocos Keeling Islands · Western Australia
Cocos Keeling Reefs
A remote Indian Ocean atoll with clear water, drift diving and very few other divers.
The Cocos Keeling Islands form a remote atoll roughly 2,750 kilometres northwest of Perth, among the most isolated dive destinations under Australian administration.
The atoll provides clear water, reef diving, drop-offs and a large lagoon, with marine life influenced by both Indian Ocean and Indo-Pacific species.
Because services are limited, planning matters more here than at almost any other Australian destination.
