Cold-water shore diving, piers, more than sixty historic wrecks and wall diving that runs well past recreational depth.
Victoria offers one of Australia's most technically interesting diving environments. It combines cold-water shore diving, pier diving, historic wrecks, deep walls, kelp, reefs and a large, experienced local diving community.
Official Victorian tourism information identifies more than 60 nineteenth-century shipwrecks and four World War I submarines in Port Phillip Bay. Port Phillip Heads also contains walls starting at approximately 12 metres and extending beyond 90 metres.

|---|---|
| Visibility | Variable and site-dependent. Pier sites can range from 2 m to 15 m; offshore and Heads sites are often clearer, particularly on slack water. |
| Season | Year-round with a well-established winter diving community. Offshore and Heads diving is strongly tide- and weather-dependent in every season. |
