Just off the coast near Port Campbell, The Arches Marine Sanctuary protects a remarkable seascape. This area is known for the above water limestone landscape, however 19 to 25 metres below the waves there is a labyrinth of towering limestone canyons, caves, arches and walls. It is these structures which give the park its name. The area is characterised by high energy waves and cool water with flows from the Southern Ocean.
The complex structures beneath the waves provide a foundation for brilliantly coloured seaweeds and sponges to grow on. Due to the shaded underside of the underwater arches, habitats here are typical of those found in the deeper waters of Bass Strait.
Conditions can change in parks for many reasons. For the latest information on changes to local conditions, please visit the relevant park page on the Parks Victoria website.
