The limestone stacks of the Twelve Apostles rise majestically from the wild Southern Ocean.  Rising out of the Southern Ocean, alongside Australia’s famous Great Ocean Road, you’ll find the 12 Apostles – limestone pillars that were once connected to the mainland cliffs. Waves and wind carved them into caves, then arches, and eventually battered them down into 45-metre (150-foot) tall columns. There are, in fact, only eight Apostles at the moment, but who knows when the next stretches of cliff will become pillars.
