Yes, you can swim with wild bottlenose dolphins in Victoria, Australia, primarily in the waters of Port Phillip Bay. Several licensed tour operators depart from towns like Sorrento and Queenscliff on the Mornington and Bellarine Peninsulas. Unlike many "captive" dolphin experiences, this is a highly regulated, nature-based activity where you enter the water with a snorkel and mask to observe the dolphins in their natural habitat. Because the dolphins are wild, sightings and interactions are never 100% guaranteed, but the local populations are known for being curious and playful. In 2026, these tours follow strict environmental protocols to ensure the animals are not stressed or harmed; swimmers must stay a certain distance away and are not allowed to touch or feed the dolphins. Most tours also include the opportunity to swim with Australian Fur Seals at Chinaman's Hat, a local seal colony. The water in Victoria can be quite cold, so tour operators provide thick 5mm wetsuits to keep you comfortable during the experience, which usually runs from late spring through early autumn.
