Parc national de Port Campbell, The Twelve Apostles

The Twelve Apostles are giant rock stacks that rise majestically from the Southern Ocean and are the central feature of the rugged Port Campbell National Park. The Twelve Apostles have been created by constant erosion of the limestone cliffs of the mainland that began 10–20 million years ago. The stormy Southern Ocean and blasting winds gradually eroded the softer limestone, forming caves in the cliffs. The caves eventually became arches and when they collapsed rock stacks up to 45 metres high were left isolated from the shore. In this photo is the biggest one from above Apostles.
