The 4 Best Snorkelling Spots in Melbourne Right Now
Choose your spot by skill level and wind direction. The sites below are ranked from easiest to most exposed.
Rye Pier, Mornington Peninsula
Rye Pier is the top pick for beginners and families. The sandy bottom stays at 2 to 3 metres along the pier pylons. Sponges, leatherjackets, and the occasional weedy sea dragon live on the structure year-round. Entry is a gentle beach walk. Conditions vary, so always assess on the day before committing to the water.
What makes Rye different from other pier dives
The pier runs north-to-south, so a southerly wind pushes a small chop onto the beach but leaves the leeward side of the pylons calm. On northerly days, the bay surface turns glassy. Pick your entry side based on the forecast. Parking is free at Rye foreshore but fills by 9 am on summer weekends.
Jawbone Marine Sanctuary, Williamstown
Jawbone sits 20 minutes from the CBD by car or a 10-minute walk from Williamstown station. The sanctuary covers 54 hectares of seagrass, rocky reef, and tidal flats. Pipefish, bream, and blue-ringed octopus all live here. Do not handle any marine life. The EPBC Act 1999 and the Marine and Coastal Act 2018 (Vic) both protect this sanctuary. Entry is from the foreshore rocks. Conditions vary, so always assess the entry on the day.
Popes Eye, Port Phillip Heads Marine National Park
Popes Eye is a circular bluestone reef 4 kilometres offshore from Queenscliff. It sits inside the Port Phillip Heads Marine National Park. You need a boat or a tour operator to reach it. Visibility here averages 5 to 8 metres in summer. Australasian gannets nest on the structure above water. Weedy sea dragons are common on the reef's sheltered north face. This is the standout site for underwater photographers.
Portsea Hole and Portsea Back Beach
Portsea Back Beach faces Bass Strait and carries a real swell. It suits confident swimmers only. The calm Portsea bay side offers much easier snorkelling on a reef shelf at 2 to 4 metres. Visibility reaches 8 to 10 metres after a calm northerly stretch. Several Mornington Peninsula dive operators run guided snorkel tours from Portsea Pier, typically from AUD $95 per person as of 2025.

When Snorkelling in Melbourne Is Actually Good
The best window runs October to March. Water temperature peaks at 19 to 21°C in January and February. Visibility is highest after a week of northerly winds and no rain. Avoid the bay for 48 hours after heavy rain. Stormwater runoff from the Yarra and Maribyrnong rivers drops bay visibility to under 2 metres near Williamstown.
Wind Direction Is Everything
Northerly winds flatten Port Phillip Bay. Southerly and south-westerly winds build a short, steep chop that cuts visibility fast. Check the Bureau of Meteorology coastal waters forecast for Port Phillip before every session. A forecast below 15 knots from the north means a good day.
Tides at Port Phillip Heads
The heads funnel a strong tidal current. Popes Eye sits close to this flow. Snorkel Popes Eye on a slack tide only. AHS chart AUS 147 covers the Port Phillip Heads area and shows the tidal streams clearly. Your tour operator will schedule departures around slack water.
Real Costs for Snorkelling Near Melbourne
Gear hire at Mornington Peninsula dive shops runs from AUD $15 to $30 per day for a mask, snorkel, and fins. A full wetsuit hire adds AUD $20 to $35. Guided snorkel tours to Popes Eye or Portsea reef typically cost AUD $85 to $130 per person as of 2025, including equipment. Family packages at some operators run from AUD $250 for two adults and two children.
Book a Guided Tour via PADI Travel
For Popes Eye and offshore reef tours, book through a licensed operator. PADI Travel lists verified Melbourne-area snorkel and dive operators at travel.padi.com. Guided tours include boat transfer, gear, and a briefing on the marine sanctuary rules. That briefing alone is worth the cost for first-timers.
Safety: Currents, Flags, and What Not to Touch
Port Phillip Bay's shore breaks are mild at most spots. The real hazard is tidal current at the heads. Always swim within your fitness level. Never snorkel alone. Check for red-and-yellow patrolled flags at beach entries and stay between them.
Marine Life Safety
- Blue-ringed octopus: common in rock crevices at Jawbone and Portsea. Do not handle under any circumstances. Their venom is potentially fatal.
- Stingrays: common on sandy patches at Rye and Sorrento. Shuffle your feet on entry to avoid a barb strike.
- Cone shells: present on reef areas. Do not pick up any shell. Under the Fisheries Act 1995 (Vic), collecting live marine invertebrates from a sanctuary is illegal.
