Underwater Navigation
Finding your way with a compass and natural references — essential for Australian shore diving.
Underwater navigation is the difference between a shore dive that ends where you parked and one that ends several hundred metres up the beach.
The course covers compass use, natural navigation using terrain and light, distance estimation by kick cycles and time, and patterns for searching or returning to a specific point.
In Australia it has particular practical value because so much local diving is shore-based, and because visibility on temperate sites often makes visual navigation unreliable.
Why it matters for shore diving
A boat dive ends when you surface and the boat collects you. A shore dive ends wherever you happen to come up, and the walk back along a rocky headland in full equipment is a genuine consideration.
Sites like Bare Island, Kurnell and Bass Point all reward divers who can return to the entry point underwater rather than swimming back on the surface.

Underwater Navigation: frequently asked questions
Do I need a compass if I dive with a guide?
Not strictly, but navigation skill makes you a more independent diver and is a prerequisite for diving without professional supervision at unfamiliar sites.
Is natural navigation enough?
In good visibility with distinctive terrain, often yes. Australian temperate sites frequently offer neither, which is where the compass earns its place.
