Cocos (Keeling) Islands
Australia · Indian Ocean Territory
One of the most remote dive destinations in the world, the Cocos (Keeling) Islands sit 2750 km northwest of Perth in the eastern Indian Ocean. This pristine coral atoll delivers encounters with scalloped hammerheads, silvertip and grey reef sharks, manta rays, and schools of pelagic fish around near-untouched reef structures. With few visitors and no land-based dive industry, the underwater wilderness here is as raw and undisturbed as it gets in Australian waters.
