Off shore of the Port Campbell National Park in Victoria,is a collection of limestone stacks known as “The 12 Apostles”.Currently only 8 of them are left & each of them holds a name significant to Australian history.These were formed over 20million yrs ago due to erosion caused by harsh & extreme weather conditions from the Southern Ocean.And as the time ticked, Mother Nature changed & carved these limestones to caves in cliffs & later to arches,now standing almost 50 mts high.A must see place
