Scuba Diving in Port Phillip Heads
Walls from 12 metres to beyond 90 — the terrain that built Victoria's technical diving culture.
Port Phillip Heads contains some of Australia's most dramatic wall diving. The walls begin at recreational depths and continue far below them, reaching beyond 90 metres.
That range makes the region relevant simultaneously to recreational wall diving, deep training, decompression diving, Trimix and full technical diving. Very few Australian sites serve that entire spectrum.
Tides and currents are the major planning consideration. The Heads are the narrow entrance through which Port Phillip Bay exchanges an enormous volume of water, and the resulting flow is not something a diver negotiates with.

Useful next reads: interpreting dive conditions, exposure protection and the Australian packing list.
Most Heads diving happens in a limited slack-water window, and that window shifts daily. Operators plan around it precisely because getting it wrong is not a minor inconvenience.
For visiting divers, this means the dive schedule is set by the tide rather than by preference, and flexibility about timing is part of the price of diving here.
Deep terrain close to a major city is rare. The Heads give Victorian technical divers somewhere genuinely worth the training, which in turn sustains the instructors, gas blending and equipment support that make the training available.
It is a good illustration of why technical capability clusters geographically rather than spreading evenly.
