Scuba Diving in Melbourne & Victoria
Victoria offers a distinctive mix of temperate-water diving within easy reach of Melbourne: sheltered piers, seagrass beds, rocky reefs, kelp forests, sponge-covered walls and a large collection of historic wrecks. Port Phillip, the Mornington Peninsula, Western Port and Phillip Island all offer very different dives, which is one reason local divers can keep discovering new sites for years.
What can you see underwater?
Local waters support an unusually varied mix of temperate marine life. Depending on the site and season, divers may encounter weedy seadragons, seahorses, cuttlefish, octopus, rays, Port Jackson sharks, blue devil fish, anglerfish, nudibranchs and large schools of fish. Seasonal events such as giant spider-crab aggregations can add another reason to revisit familiar sites.
The habitat can be as interesting as the animals. Piers provide structure for sponges, ascidians and small invertebrates, while reefs and walls support kelp, colourful sponge gardens and larger reef species. Wrecks add history and structure to many of Victoria’s boat-diving options.
Is the water cold?
Victoria is a temperate-water destination, so appropriate exposure protection matters. The right wetsuit or drysuit, hood, gloves and thermal layers can make year-round diving comfortable for many divers. Conditions vary by season, location and depth, so plan for the actual dive rather than relying on a single “Melbourne water temperature”.
Why learn locally?
Training in local conditions gives divers experience with cooler water, variable visibility, changing weather and different entry types while they are under professional supervision. That experience can help build adaptability and confidence before travelling to other destinations. It also means your certification immediately opens up a large range of diving close to home.

Port Phillip and the Mornington Peninsula
Choose between shore diving around piers and reefs, and boat trips to walls and wrecks. Port Phillip Heads adds a different scale of diving: sites such as Portsea Hole and the entrance walls require suitable experience and careful planning around tides and conditions. The Peninsula also offers opportunities to explore temperate reefs and seagrass habitats from shore.

Western Port and Phillip Island
Western Port’s seagrass habitats and tidal channels provide a different environment from Port Phillip. Around Phillip Island, choose sites with the team according to experience and the forecast. An appealing location on a map is only a starting point: current access, tide, swell and visibility determine whether a dive is appropriate.

Learn. Explore. Protect. Belong.
Learn: Regular local diving offers opportunities to practise buoyancy, navigation and equipment handling, building adaptability and environmental awareness over time. Start with Learn to Dive or explore continuing education.
Explore: Return to familiar sites through different seasons. Changing temperatures, weather and marine activity can make the same reef feel very different; good conditions and wildlife sightings are never guaranteed.
Protect: Keep fins and equipment clear of the seabed and observe wildlife without handling or disturbing it. Explore conservation, SSI Ecology and our independent AA Exclusive Conservation Training.
Belong: Find regular diving companions through our community and calendar. Tell the team about your experience, recent diving and interests so we can help you find a suitable outing.
Plan for the actual conditions
Planned dates are genuine, but weather and safety can require a different site, timing or reschedule. Check current access and notices before travelling, and follow the dive briefing. Safety takes precedence over the timetable.
For official destination information, see Parks Victoria’s diving guide and Port Phillip Heads Marine National Park.
