Ocean pools are an important feature of the Australian coastline particularly in New South Wales. Ocean pools or ocean baths are defined as public seawater pools sited on a rocky surf coast, so that waves can wash into the pool. The width, length and depth of ocean pools varies and often depends on their location on the coastline. Australia also has many harbour pools and these are usually netted or fenced and located in harbours or river mouths but not regarded as ocean pools.
