Safety And Conservation
This is a high-reward destination for mixed-skill groups, but tides, boat traffic, and rapidly changing visibility require conservative decisions. Treat Moreton Bay as a managed marine park: follow zoning, respect wildlife, and avoid anchoring or touching reef structure.
Top Risks
- Primary risk: Tidal current at the wrecks
- Secondary risk: Boat and jet ski traffic
- Emergency contact: Emergency Services (000)
- Safety overview: This is a highreward destination for mixedskill groups, but tides, boat traffic, and rapidly changing visibility require conservative decisions.
Dive safety
Wreck and Bay Safety
- Dive or snorkel at slack tide: current can run between the beach and the wreck line when the tide is moving.
- Assume boat traffic: keep your group tight, tow a float for snorkel or freedive sessions, and carry an SMB for scuba ascents.
- Stay off the bottom: kicking up sand can reduce visibility quickly for everyone.
Offshore Reef Safety
- Respect the forecast: offshore trips are exposed to wind chop and swell. Operators may change sites or cancel if conditions are unsafe.
- Be conservative with navigation and gas: if surge increases, shorten the plan and avoid pushing penetration or swim-through ideas.
Common Conditions
- Visibility: can range from 2 m in stirred-up bay water to 20 m on calm, clear stretches.
- Temperature: plan exposure for roughly 20°C in winter and 26°C in late summer.
Brisbane has specialist hyperbaric support for diving injuries. The Royal Brisbane and Women's Hospital Hyperbaric Medicine Service provides a statewide service with a 24-hour on-call capability supporting Queensland's recreational and commercial dive industries.
On Moreton Island, medical facilities are limited. In serious emergencies, call 000 and follow instructions for evacuation and transfer.
Snorkel and freedive safety
Tidal current at the wrecks
Current can run strongly between the beach and the wreck line when the tide is moving. Plan for slack tide, do not fight the current, and use flotation or a guided boat drop if unsure.
Boat and jet ski traffic
Popular wreck areas can have frequent watercraft traffic. Stay close to your group, use a surface float, and deploy an SMB on ascent.
Rapid visibility changes after wind or rain
Moreton Bay can go from clear to milky quickly. If visibility drops below 3 m, switch to sheltered coves or move your water session to another day.
Cold stress in winter water
Long sessions in 20°C water can lead to shivering and poor decision-making. Pack a 5mm suit and warm layers for the boat ride back.
Wildlife and protected areas
Marine Park Rules That Matter
- Know your zone: Moreton Bay Marine Park includes no-take areas where taking or collecting marine life is not allowed.
- Designated areas add extra rules: these include go-slow wildlife areas designed to reduce boat strike on turtles and dugongs, and no-anchoring areas that protect sensitive habitat.
- Extra protections in some areas: some sites have additional restrictions intended to protect critically endangered grey nurse sharks.
Low-impact Water Etiquette
- Maintain buoyancy and avoid contact with coral, wreck structure, and the seafloor.
- Do not feed marine wildlife. Keep encounters passive and give turtles and dolphins space.
- Use public moorings where provided and avoid anchoring on reef or seagrass.
On-island Care
- Stay on designated tracks, respect closures, and pack out all rubbish.
- Treat dunes and nesting areas as fragile habitat and avoid night lighting on beaches.
Do Not Do This
Avoid entering when tidal current at the wrecks. Confirm local briefings before committing.
