The Twelve Apostles – Great Ocean Road

The Twelve Apostles Which Were Pigs Before –  But Never More Than 9 Limestone Stacks  :-D

The Twelve Apostles is a collection of limestone stacks off the shore of the Port Campbell National Park.

The Twelve Apostles were originally called The Sow and Piglets. The Sow was Mutton Bird Island, which stands at the entrance to Loch Ard Gorge and her Piglets were the numerous rock stacks located along the coast. As coast and these limestone stacks got more and more popular they found a more „esthetic“ name: The Twelve Apostles.

The Apostles were formed by erosion. The harsh and extreme weather conditions from the Southern Ocean gradually eroded the soft limestone to form caves in the cliffs, which then became arches, which in turn collapsed; leaving rock stacks up to 45 meter high. The formation eventually became known as The Twelve Apostles, despite only ever having nine stacks.

The rate of erosion at the base of the limestone pillars is approximately 2 cm per year. Some of the Twelve Apostles are already eroded and more will erode and break.  On the other hand due to wave action eroding the cliff face, existing headlands are expected to become new limestone stacks in the future. So there is always a coming and going  :-P
