The Twelve Apostles is a collection of limestone stacks off the shore of Port Campbell National Park, by the Great Ocean Road in Victoria, Australia. The extreme weather conditions from the Southern Ocean gradually erode the soft limestone to form caves in the cliffs, which then become arches that eventually collapse, leaving rock stacks up to 50 metres high. The stacks are susceptible to further erosion from waves. In July 2005, a 50-metre-tall stack collapsed, leaving seven standing at the Twelve Apostles viewpoint. Due to wave action eroding the cliffs, existing headlands are expected to become new limestone stacks in the future. There are in fact thirty different limestone masses stretched along this coastline.
