The boat noses out from Sorrento Pier and the cold spray catches the light; Port Phillip Bay opens like a quiet room where seals surface to inspect new visitors. In shallow water off Chinaman’s Hat, juvenile Australian fur seals thread through the kelp, curious and quick, while the skiff rocks gently and guides brief the group. Later, the kelp forests at the seadragon site sway like slow hands and, if you watch closely, a weedy seadragon drifts into view—ornate, ghostly and designed to vanish.

This stretch of the Mornington Peninsula sits on ancient volcanic and sedimentary foundations; cliffs and sandy flats reflect a coastline shaped by sea-level changes and strong tidal exchange into Port Phillip. The area carries layers of cultural history — the Boon Wurrung peoples’ connection to these waters and later European coastal use — and it’s now protected as marine habitat with active conservation measures.
Practically: tours depart daily from Sorrento, last about two hours, and include wetsuits, snorkel gear, lunch and hot drinks. Water temperatures can be bracing year-round, so a wetsuit is standard; guides teach safe approaches to wildlife and enforce no-touch rules. Be ready for short boat transfers, shallow kelp drifts, and intermittent current — the seals may choose how close to get.
Plan for a calm-weather window (operators cancel in rough conditions), carry reef-safe sunscreen, and come with basic swimming comfort. The experience balances close marine encounters with clear rules to protect animals and visitors alike, making it both thrilling and responsible.

The Mornington Peninsula’s coastline has long been significant to the Boon Wurrung people and later maritime traffic; local reefs and bays were historically used for fishing and small-boat navigation.
These waters are managed to reduce disturbance to marine life — do not feed or touch wildlife, use reef-safe products and follow guide instructions to minimize impact.
Moonraker Dolphin Swims operates guided outdoor trips and adventures with an emphasis on safety, stewardship, and memorable experiences.
