1

Rye Pier for Night Snorkelling

Located just a short drive from the Searoad Ferries Sorrento terminal, Rye Pier is one of the most easily accessible destinations for snorkelling near Melbourne. Underwater lies the Octopus Garden Marine Trail, a 200-metre snorkelling trail marked with interpretive signs that highlight the pier’s rich marine community. What makes Rye Pier a fascinating spot is the different snorkelling and scuba-diving experiences it offers at night, thanks to the resident nocturnal marine life.

Safety tip for night snorkelling at Rye Pier: Visibility is limited after dark, so a waterproof diving torch is essential. Always check weather, wind, and tide conditions before entering the water, and never assume calm conditions at night just because the bay looks still. Stay within the marked trail and close to the pier, avoid boat channels, and snorkel with a buddy at all times. Choosing calm evenings with minimal wind and good water clarity will make night snorkelling at Rye Pier both safer and more rewarding.

What You Might Spot Underwater:

Bigbelly Seahorse (Pot Belly Seahorse), Shorthead Seahorse, Smooth Stingrays, Giant Spider Crabs, Southern Blue-ringed Octopus, Southern Keeled Octopus, Maori Octopus, Southern Sand Octopus, Australian Fur Seals, Giant Australian Cuttlefish, Puffer Fish, Decorator Crabs, and more. Remember to never touch,  handle, or pick up a Southern Blue-ringed Octopus when you see one. While they are not aggressive and generally shy, they will bite if they feel threatened, provoked, or handled.

Best Times and Conditions for Snorkelling

Every snorkelling site is different, so it’s best to check site-specific information on the best times and conditions for snorkelling. Use this guide when snorkelling within Port Phillip Bay and Western Port. [1]

 

1

Seasonal Considerations

Winter usually has more northerly winds, which often means calmer seas and better underwater visibility than in summer. In summer, strong southerly sea breezes tend to build in the afternoon as the land heats up and pulls air in from the ocean, making conditions rougher, especially around 3 PM. This makes early mornings the best time to snorkel on hot summer days.

2

Water Quality and Weather Conditions

After heavy rain, freshwater runoff can accumulate on the surface of Port Phillip Bay, reducing visibility and water quality. Sediment from river mouths can also carry toxins and unpleasant microbes that may affect your health.

Quick Tip: Wait at least 24–48 hours after rain before snorkelling. This allows sediment and runoff to disperse, giving you clearer water and a safer underwater experience.

3

Tide and Currents

Low tide is generally the most common preference as it’s easier to get to the sea floor. However, it can also stir up sediment, especially if there’s wind and current.  As the tide starts to rise, cleaner water often flows into the area, improving visibility, so just after low tide is often the best time to snorkel.

4

Seasonal Marine Life Highlights

Marine life can be more active and diverse during the warmer months (spring/summer/autumn). However, specific species are more active during winter, and some, such as squid and flathead, are available year-round.

Snorkelling Safety Tips and Gear Essentials

1

Ensure You Have all the Essential Gear

Use a well-fitting mask, snorkel, and fins that are comfortable and in good condition to prevent water leaks or discomfort. A wetsuit or rash guard not only helps with sun protection but also keeps you warm and adds buoyancy. Aqualung, Oceanpro, and TUSA are some of the most trusted brands for snorkelling and diving gear. For wetsuits, Torquay outlets stock high-quality options from Rip Curl and Quiksilver, designed for full flexibility for snorkelling or surfing.

2

Check Equipment

Always inspect gear before entering the water: test your mask seal, clear your snorkel, and make sure fins fit properly. Practising with your equipment in shallow water or a pool first can help you feel confident. Rinse and store equipment properly after use to prolong its life and maintain performance.

3

Consider a Buddy System

Never snorkel alone. Always go with a buddy so you can look out for each other and stay aware of conditions and hazards. Establish simple hand signals and stay within sight of each other at all times for added safety.

4

Observe Marine Life from a Respectful Distance

Do not touch, chase, or feed animals, as this can stress them or provoke defensive behaviour. Maintain control of your fins to avoid accidentally damaging sensitive habitats like kelp beds or disturbing bottom-dwelling animals. Also use reef-safe sunscreen to minimise chemical harm to marine ecosystems.

Frequently Asked Questions

1. Where can I see weedy seadragons near Melbourne?

They’re commonly seen at Portsea Pier, and notable populations are found at Flinders Pier in Western Port Bay, which is considered one of the best places in Victoria to spot them.

2. Is snorkelling at Rye Pier safe for beginners?

Yes, thanks to its calm, sheltered waters and accessible entry points. The Octopus Garden Trail is suitable for novice snorkellers and is often where various marine life can be found. Remember to exercise caution around boat traffic and ensure you have an experienced buddy with you at all times.

3. What month is jellyfish season in Australia?

Jellyfish season in Victoria typically runs from November to May, when warmer ocean waters bring more jellyfish closer to shore. In Port Phillip Bay, the Catostylus (Blubber) and Cyanea (Hair jelly, Snottie, or Lion's Mane) can be seen. Reactions to jellyfish stings can vary by species and individual sensitivity, ranging from mild irritation to more severe effects. Seek first aid or medical assistance if stung. [2]

Really enjoyed taking the ferry. Not very busy, easy to get on and off with car and nice ship. Comfortable lounge and even had a sandwich. Really like the driving it saved us. Put us in great shape for starting the Great Ocean Road.
