The Arches Marine Sanctuary

To the south of Port Campbell, offshore in 20 metres of water, the limestone seafloor breaks up into a series of amazing canyons, arches and tunnels that are locally known as 'The Arches'. This area is typical of the southwest Victorian coast and exposed to high-energy waves and cool water that flows from the Southern Ocean.


This 45 hectare marine sanctuary contains some of Victoria's most spectacular limestone formations and is home to a diverse array of marine plants and animals. Due to the shaded underside of the Arches, habitat is provided for invertebrate life that is characteristic of deeper Bass Strait waters and includes a diverse range of sponges, bryozoans, gorgonians, hydroids and an abundance of colourful seastars. Giant kelp forests also occur within the Marine Sanctuary.


Things to Do

The area is a popular destination for dive charters due to the spectacular underwater scenery.
