Key safety practices for Cocos diving and snorkelling:

Be current-aware. The Rip and channel areas can accelerate quickly with tide changes.
Carry surface signaling on every dive: SMB, whistle, and a light if you may surface late.
Dive conservatively and stay well within no-decompression limits. This is a remote destination and evacuation is complex.
If you feel unwell after a dive, treat it seriously early and contact emergency services.
For snorkel drifts, use fins, a buddy, and a clear pickup or exit plan.

Medical care is limited on-island. For serious illness or injury, patients may require air evacuation to mainland Australia (Perth). There is no guarantee of rapid access to a recompression chamber, so dive insurance that covers evacuation is strongly recommended.

For emergencies:

Call 000 (or 112 from a mobile) for police, fire, or ambulance dispatch.
Notify your dive operator and provide oxygen if trained and equipped.

The Rip is a highlight but it is not a casual swim.

Treat it as an advanced drift environment
Only go with a clear exit plan and local advice
Use fins, a buddy, and surface signaling

Plan conservative dive profiles and buy appropriate insurance. Medical resources are limited and serious cases may require air evacuation to mainland Australia.

From roughly May to October, stronger winds can create rough lagoon and outer-reef transits. Pack motion-sickness meds and protect cameras in dry bags.

Use good buoyancy and wear exposure protection when you are close to reef. Rinse scrapes promptly and carry a basic first-aid kit for minor cuts.

The Cocos (Keeling) Islands sit inside a large Australian Marine Park, and North Keeling is protected as Pulu Keeling National Park. Conservation is not optional here:

Follow zone rules, especially green zones where take is prohibited.
Do not touch, chase, or ride wildlife. Give turtles and rays space.
Avoid anchoring on coral and use moorings where provided.
Take all rubbish back with you, including fishing line and micro-plastics like cable ties.
Choose reef-safe sunscreen and avoid standing in shallow coral.
