Located on the coast of Port Campbell National Park The Twelve Apostles is a vast collection of various stacks of limestone. Thanks to the proximity of the limestone stacks of each other, this site has become one of the sites most popular tourist attraction. Erosion is credited for the formation of the apostles. The Southern Ocean has adverse climatic conditions gradually eroded in the limestone cliffs to form caves. Later along, the caves became arches that collapsed leaving some rock stacks with a height of 45 meters. Until 1922, the site was referred to as Sow and Piglets. The sow was Muttonbird Island and the tiny piglets were piles of rock.
In 2002, the Port Campbell Professional Fishermens Association unsuccessfully attempted to block the creation of a proposed marine national park at the Twelve Apostles location,but were satisfied with the later Victorian Government decision not to allow seismic exploration at the same site by Benaris Energy; believing it would harm marine life.
The stacks are susceptible to further erosion from the waves. On 3 July 2005, a 50 metre tall stack collapsed, leaving eight remaining.(compare the two pictures from 2002 and 2012). On 25 September 2009, it was thought that another of the stacks had fallen, but this was actually one of the smaller stacks of the Three Sisters formation. The rate of erosion at the base of the limestone pillars is approximately 2 cm per year.Due to wave action eroding the cliff face existing headlands are expected to become new limestone stacks in the future.
