Conditions: Geographe Bay is often calmer than the west-coast capes, but visibility can still drop after wind. Treat cape sites as advanced and condition-dependent.
Wreck safety: do not penetrate the HMAS Swan without training, redundant gas, and proper equipment.
Surface management: use a surface marker buoy and stay aware of vessels, especially near Busselton Jetty and boat ramps.
Cold management: winter water can be around 15°C under the jetty. Bring warm layers for surface intervals.
Emergency plan: know your exit points, and carry a phone in a waterproof case for shore dives.

Busselton and Margaret River have local hospitals for initial assessment. For serious diving injuries, evacuation and specialist treatment may involve transfer to Perth. Carry dive accident insurance (for example, DAN) that covers hyperbaric treatment and medical transport, and save emergency numbers before you enter the water.

Ngari Capes coastline can be exposed to large, uninterrupted ocean swells. If surge is strong or entries look unsafe, pivot to Geographe Bay dives or topside plans.

Use a surface marker buoy where appropriate, stay within designated areas, and avoid surfacing unexpectedly in vessel corridors.

Water temperatures under the jetty can drop to about 15°C in July. Longer dives and repeated sessions require thicker exposure protection and warm layers between dives.

Ngari Capes Marine Park protects key habitats including seagrass meadows and supports whale migration corridors. In sanctuary zones, do not fish or collect, including taking shells. Keep all diving and snorkelling non-extractive, maintain good buoyancy to avoid damaging sponge growth on jetty pylons, and do not feed wildlife. If you encounter rays or large fish like western blue groper, give them space and let them approach on their terms.
