Safety And Conservation
Jervis Bay sits inside a well-managed marine protected area network, but that also means rules are part of the dive plan. Check Jervis Bay Marine Park zoning, respect no-take sanctuary zones, and follow Booderee's additional restrictions on anchoring and gear. For shark encounters, treat grey nurse sharks as protected wildlife and use a calm, non-intrusive approach.
Top Risks
- Primary risk: Open-coast surge at caves and gutters
- Secondary risk: Rogue waves on headlands and rock platforms
- Emergency contact: Triple Zero (000)
- Safety overview: Jervis Bay sits inside a wellmanaged marine protected area network, but that also means rules are part of the dive plan.
Dive safety
On-water and Underwater Safety
- Choose the right site for the day: open-coast caves and gutters are sensitive to swell and surge.
- Surface with visibility: carry an SMB and deploy it before your final ascent when boat traffic is present.
- Stay conservative in caves: remain within the light zone unless you have specific overhead training and the operator approves.
- Thermal management: plan for wind chill on boats, especially in winter.
Grey Nurse Shark Best Practice
- Do not touch, feed, chase or harass sharks.
- Do not block cave or gutter entrances or interrupt swimming patterns.
- Avoid scooters or other mechanical devices and keep group sizes small.
For urgent emergencies in Australia, call 000 (or 112 from mobiles). For suspected DCS or other dive injuries, call a dive medicine hotline early and follow their evacuation advice.
- Shoalhaven Hospital Emergency Department (Nowra) is the closest major ED.
- Prince of Wales Hospital Diving and Hyperbaric Medicine (Randwick, Sydney) is a key hyperbaric referral unit.
- DAN Emergency Hotline can provide 24/7 medical advice for divers.
Snorkel and freedive safety
Open-coast surge at caves and gutters
Slot Cave and similar sites can have strong surge even when the bay looks calm. If you are not comfortable in surge, ask the operator for a more sheltered option.
Rogue waves on headlands and rock platforms
Rock platforms can be slippery and exposed. Watch sets for several minutes before committing to an entry, and always keep an exit option.
Boat traffic near ramps and channels
Areas around Huskisson and popular beaches can be busy. Use a surface float, carry an SMB and avoid surfacing in channels.
Cold stress and wind chill in winter
Even if the dive is great, cold hands and wind on the boat can end the day early. Bring warm layers, a beanie and a thermos in winter.
Wildlife and protected areas
Marine Park Zoning and No-take Rules
- Jervis Bay Marine Park includes sanctuary zones (no-take) plus habitat protection and general use zones. Some activities (like spearfishing) are restricted in specific areas such as creeks and the Hyams Beach habitat protection zone.
- Booderee National Park includes a Bowen Island sanctuary zone where fishing and collecting are prohibited and anchoring is prohibited.
Anchoring and Habitat Protection
- Booderee's marine activities guide asks visitors to anchor only in waters greater than 10 m deep to reduce seagrass damage.
- In Booderee, anchoring is not allowed in depths less than 10 m at mean low tide in specified areas, and it is prohibited in sanctuary zones.
What Not to Take
- Booderee protects shellfish (including pipis and abalone) and rock platform species. It also lists protected species such as grey nurse shark, estuary cod, eastern blue devilfish, elegant wrasse and all seahorses, seadragons and pipefishes.
- Spearfishing is prohibited in Booderee waters.
Do Not Do This
Avoid entering when open-coast surge at caves and gutters. Confirm local briefings before committing.
