Dive sites by state · 2026 guide
Victoria has 8 dive sites in our database. These are the 8 with the strongest combination of reputation, marine life and confirmed operators.
Each entry shows the typical depth, the certification it suits and who runs trips there.
1Port Phillip Heads, Victoria
Walls starting at 12 metres and continuing beyond 90 — the terrain behind Victoria's technical culture.
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.
Look for: Australian & New Zealand Fur Seals

2Mornington Peninsula, Victoria
Victoria's signature artificial wreck — a former guided missile frigate at around 28 metres.
Visit Victoria places the wreck at approximately 28 metres. Access requires a licensed operator or use of the public mooring system.
Look for: temperate reef fish, sponges and soft corals colonising the structure, schooling baitfish, seals occasionally in the area
3Mornington Peninsula, Victoria
Victoria's most popular pier dive, and the best-known site for giant spider crab aggregations.
It is best known internationally for the giant spider crab aggregation, when tens of thousands of crabs gather in the shallows to moult.
Look for: Giant Spider Crab, Nudibranchs, Seahorses & Pipefish, Weedy Seadragon

4Mornington Peninsula, Victoria
A shallow, sheltered pier known for seahorses, seadragons and night diving.
The piles and surrounding sand hold seahorses, weedy seadragons, octopus and an excellent range of macro subjects, and the site is heavily used for training.
Look for: Giant Spider Crab, Nudibranchs, Seahorses & Pipefish, Weedy Seadragon

The bay's network of pier dives — the accessible heart of Victorian diving.
They provide access to seahorses, weedy seadragons, rays, squid, crustaceans and dense macro life, often in only a few metres of water.
Look for: Giant Spider Crab, Seahorses & Pipefish, Weedy Seadragon

6Mornington Peninsula, Victoria
A Western Port pier with one of Victoria's most reliable weedy seadragon populations.
The seagrass and kelp around the piles support a resident population, and the shallow depth makes for very long, relaxed dives.
Look for: Weedy Seadragon

7Geelong & Bellarine Peninsula, Victoria
Numerous vessels deliberately scuttled outside Port Phillip Bay across a wide depth range.
Different wrecks lie at different depths, ranging from accessible recreational profiles to depths that require Trimix and full decompression planning.
Look for: sponge and soft coral colonisation, temperate reef fish, crayfish, schooling baitfish, seals occasionally
8Port Phillip Heads, Victoria
Victoria's signature wall — sponge-covered, vertical, and continuing well past recreational depth.
The shallower sections are within reach of competent recreational divers on slack water; the deeper sections are a genuine technical undertaking.
Look for: Australian & New Zealand Fur Seals
