Oceanic Victor

This unique marine experience lets you swim with Southern Bluefin tuna – dubbed ‘the Ferraris of the ocean’ – in a specially designed in-sea aquarium on Granite Island, an hour south of Adelaide. Departing from the busy tourist hub of Victor Harbor, a quick catamaran ride delivers you to the aquarium where you're fitted out with a wetsuit, mask, booties and gloves before diving into the clear, clean waters of Encounter Bay to experience tuna up to 2.5 metres long whooshing past your body with impressive speed. Those who prefer to stay dry can feed the tuna from the surface, or view the sights from the glass-sided underwater viewing area.
