The pier smells faintly of diesel and seaweed as the luxury boat eases away from Sorrento; gulls wheel overhead and the shallow bay opens like a bright, silvery floor. Guides fit you with a full-length wetsuit and mask, and the water’s surface glints with the possibility of seals’ curious faces and dolphin whistles that seem to come from everywhere.

Port Phillip Bay is a broad, shallow basin carved by coastal processes and fed by rivers; its sheltered shallows and kelp beds create pockets of habitat that support weedy sea dragons, fur seals and a resident population of bottlenose dolphins. European settlement reshaped the coastline—quarries and jetties from the 19th century remain—but the bay’s marine life has persisted, drawing naturalists and snorkelers to the Mornington Peninsula for decades.
Expect close, respectful encounters rather than performances: seals investigate, sea dragons drift among algae, and dolphins decide whether to approach. Encounters vary—sometimes pods circle slowly, other times they pass in a flash. The operator uses small-group entries and strict wildlife etiquette to minimize disturbance.
Practicalities: meet at Sorrento Pier, plan for a 3‑hour tour with guided snorkeling, and note full wetsuits, snorkel gear, hot showers and lunch are provided. Bring a towel, reef‑safe sunscreen, and seasickness meds if you’re prone to motion. You must have basic swimming ability; tours are weather dependent and may be rescheduled. If dolphins aren’t seen, most operators offer a free return within the stated rebooking window. Early bookings in summer fill fast—arrive prepared and patient, and the bay will often reward you with unforgettable, up-close marine moments.
