Bay Freediving Sites

Includes a visit to sites ranging from Banksia Reef, Pope’s Eye Marine Park, Chinaman’s Hat, South Channel Fort or Point Nepean Bay. Excursions are for all certified freedivers (minimum Level 1) and tailored for you to experience the best conditions and sites on the day. Special adventures are also scheduled to explore new undiscovered territories.

The Bay here is beautiful with sandy beaches and exposed coastal cliffs. The water is generally cleaner and clearer and in summer months reaches temperatures up to 21 degrees.

Marine Wildlife & Seals

Port Phillip Bay’s Australian Fur Seals once upon a time were under threat, but nowadays they thrive with their restful haul-out platforms. A highlight of any wildlife experience, swimming with seals shows you their diving agility, playfulness and acrobatic skills! Their breath-hold performance will amaze you too.

An excursion from Sorrento is the best way to experience the thriving reefs, both natural and artificial, that give protection to fish, seadragons, stingrays, cuttlefish and crabs. The southern temperate waters are home to marine species, 80% of which don’t exist anywhere else on earth. Our smooth rays are the largest stingray species in the world. Blue-throat wrasse are a key live export fish favoured in asian cuisine. The annual spider crab migration is a little understood highlight of our local region. Other unique species of fish such as Long-snout Boarfish, Old Wives and Weedy Seadragons will delight you with their ornamentation and vibrant colours.

Bay Freediving Boat Dive Adventure

Make your way to Sorrento on the Mornington Peninsula to meet your local guide and your rigid inflatable boat (RIB). Sorrento is around a 1.5hr drive from Melbourne.

Meeting at the Sorrento Boat Ramp Jetty at least 30 minutes before departure (allow more time in summer), you’ll be greeted by your Guide and introduced to fellow guests.

Slip into your wetsuit and listen to a short briefing on what to expect during the 2-hour boat excursion. Hop in to the boat and take your seat; it may be a lively ride.

On the way out of port, pass the Sorrento-Queenscliff ferry terminal built in 1870 which used to meet the Sorrento Steam Tram Service 1890-1920 to take passengers through Sorrento’s main street to the ocean beach on the other side of the peninsula (locally known as the backbeaches).

Continuing by the scenic coastline you’ll take in the Sorrento Sailing and Couta boat club towards Sullivan Bay and the Sisters Cape, the site of Australia’s first European settlers at Collins Settlement (1872).

The boat will pick up speed as it leaves the sanctuary of the coves and beaches, beyond the Blairgowrie Yacht Squadron Marina out into the bay and the skipper will zoom us out around 3 kilometres to the South Channel Pile Light where the seals await your arrival.

Upon arriving, view the architecturally rare construction of the South Channel Pile Light, one of only two surviving examples of four original manned pile lights that originally serviced ships entering Port Phillip Bay. Finally extinguished in 1985 after 111 years of service, the lantern remains intact and an important example of 19th century light technology in Victoria.

Inside the single-storey octagonal timber building comprised the light-keepers quarters which included a bedroom, living-room, storeroom, and an external verandah. There were also two rainwater tanks for domestic use. The quarters were manned by the light-keeper until bottled acetylene gas was introduced for lighting purposes in 1925.

Between 1905 and 1913, the light-keeper painted murals of ships on the interior walls of the quarters. In 1979, these were relocated to the Melbourne Maritime Museum (Polly Woodside).

Here at the Light, you’ll encounter the Bay’s iconic Fur Seals, the largest and most robust fur seal. Up to 2 meters in length and over 200kg, they’re quite a sight and incredibly agile being able to dart in all directions.

Above water you’ll hear them vocalising, which helps them identify both neighbours and strangers. You’ll delight in their inquisitive and friendly manner in the water as they swim around.

Incredible breath-hold swimmers, dives of 3-4 minutes long have been recorded by these seals, with the longest 6-7 minutes. It’s believed they may hold their breath for as much as up to 10 minutes and can reach depths of down to 200m!

Once back on the boat, scanning the horizon you may see the man-made island of South Channel Fort, an artificial island constructed during the 1880s as part of a defensive strategy. Continuing its original objectives, it now protects a colony of white-faced storm-petrels and as such is identified as an Important Bird Area by BirdLife International.

Further in the distance to the south you may see Mud Island, an uninhabited exposed area of the Great Sands which is the most extensive sand bank in Port Phillip Bay. Declared in 1982 as a Ramsar Site, a wetland of international importance owing to the sanctuary it provides white-faced storm-petrels. Crested terns, pelicans and penguins are also known to breed there.

Depending on the needs of the group, the journey may include a second pause at another significant location such as Chinaman’s Hat, Pope’s Eye Marine Park or even Banksia Reef, chosen for it’s optimal experience based on the best tides and conditions on the day.
