The Twelve Apostles are an example of a coastal landform, that are of great significance to Australia. The apostles are limestone stacks, which were formed by the forces of erosion by wind and waves. They share characteristics with all coastal landforms, as they are found on the coastline and are formed by erosion (Mraz,J et al. 2007, Humanities Alive Geography 2: for Victorian essential learning standards John Wiley & sons, Milton, Queensland ). The Twelve Apostles are a significant drawcard for domestic and international tourists.
