Wild dolphins and dugongs by day, wall dives on the Indian Ocean edge when conditions line up

Safety And Conservation
Shark Bay is remote and strongly regulated to protect wildlife and World Heritage values. Your biggest safety wins are planning around wind, respecting restricted areas (especially at Monkey Mia and Hamelin Pool), and treating outer-edge water time as an optional bonus rather than a guaranteed daily activity.
Top Risks
- Primary risk: Wind-driven chop changes plans fast
- Secondary risk: Remote 4WD sand driving
- Emergency contact: Emergency services (000)
- Safety overview: Shark Bay is remote and strongly regulated to protect wildlife and World Heritage values.
Dive safety
- Remote, weather-driven diving: outer-edge sites like Steep Point can be exposed. If swell or wind is up, do not force it.
- Tides matter: plan boat dives around slack tide when possible, especially near headlands and passages.
- Surface signaling: carry an SMB and audible signal. If diving from shore or small craft, display a dive flag.
- Boat awareness: keep a safe distance from active dive flags and avoid busy ramps and channels.
- Stings and spines: stonefish are venomous and can be hard to see in shallow water. Wear booties and avoid standing on reef or seagrass edges.
- Heat management: dehydration raises risk for dive and freedive incidents. Drink water consistently and avoid long hot drives immediately after deep or repetitive dives.
Denham has local medical services, but advanced care is limited and serious cases may require transfer to larger hospitals.
- For life-threatening emergencies, dial 000 and request an ambulance.
- For diving-related emergencies, call 000 first, then contact the DAN Emergency Hotline (within Australia 1800 088 200) for specialist support.
- The nearest hyperbaric medicine capability for diving injuries may involve transfer to Perth. Fiona Stanley Hospital has a Hyperbaric Medicine Unit (contact via the hospital helpdesk).
Carry a basic first-aid kit, have a plan for oxygen availability on boat dives, and make sure your travel insurance covers remote evacuation.
Snorkel and freedive safety
Wind-driven chop changes plans fast
Sea breezes can build quickly and affect visibility, comfort, and safety. Prioritize early water sessions and be willing to swap a snorkel for a lookout when whitecaps appear.
Remote 4WD sand driving
Francois Peron and Steep Point involve deep sand, no services, and long recovery times. Carry recovery gear, lower tyre pressures appropriately, and travel with a second vehicle when possible.
Stonefish and shallow reef hazards
Stonefish are venomous and hard to see in shallow water. Wear booties, avoid standing on reef or seagrass edges, and shuffle carefully if you must wade.
Dolphins are not a swim-with activity at Monkey Mia
The dolphin experience is ranger-managed for animal welfare, with strict rules and restricted areas. Do not enter closed sections of water, and never approach or touch dolphins.
Wildlife and protected areas
Shark Bay's rules are not optional. They protect dolphins, dugongs, turtles, and globally significant habitats.
- Monkey Mia dolphins: stay behind ranger rope lines, do not touch dolphins, and never attempt to feed them.
- Wildlife approach distances: keep respectful distances from dolphins and whales on the water, and do not harass animals for photos.
- Hamelin Pool Marine Nature Reserve: do not walk below the high tide mark, and do not swim, dive, or snorkel over stromatolites or within 300 m of shore.
- Sanctuary zones: some areas are 'look but do not take'. Check zoning maps before fishing or spearfishing.
- Seagrass protection: seagrass is critical dugong habitat. Avoid trampling and use established moorings or sand patches rather than anchoring on vegetation.
- No feeding wildlife: do not discard bait or fish waste near shore, and do not feed dolphins or seabirds.
Do Not Do This
Avoid entering when wind-driven chop changes plans fast. Confirm local briefings before committing.
