Extra Divers Christmas Island is the main dive operation on one of Australia's most remote and geologically dramatic dive destinations.
Christmas Island is the exposed tip of a seamount, and the consequence underwater is spectacular: the reef drops vertically into very deep water almost immediately offshore. Wall diving of this kind is rare in Australian territory, and in places it is accessible from shore rather than requiring a long boat run.
Water clarity is routinely excellent, often twenty to forty metres, and the walls carry hard coral, endemic reef species and regular pelagic activity. Dolphins are common, and whale sharks visit seasonally — broadly November to April, coinciding with the island's famous red crab spawning, which is itself one of the great wildlife spectacles on earth.
The island is closer to Jakarta than to Perth, and that remoteness shapes everything. Flights are limited, accommodation is finite, dive services are provided by a small number of operations, and medical evacuation distance is a genuine planning consideration rather than a formality.
None of this is a problem if planned for and all of it is a problem if not. Equipment availability, rental sizing, cylinder and gas supply all need confirming before departure rather than on arrival, because there is no alternative supplier.
Worth confirming: rental equipment range and sizing; Nitrox availability and whether any technical gas is held; certification minimums for the deeper wall sites; flight and accommodation arrangements, which generally need booking well ahead; and dive insurance covering remote evacuation. For photographers, the wall topography and clarity make this one of the more rewarding destinations under Australian administration.
Flights to Christmas Island are limited and the island's accommodation is finite, so the trip needs booking as a whole rather than assembled piecemeal. The red crab migration and spawning, roughly November to January, is worth timing around — it coincides with whale shark season.
