Beaufort Inlet also locally known as Pallinup Estuary is an inlet located in the Great Southern region of Western Australia about 130km east of Albany.The inlet functions mostly as a result of wave energy and is a wave dominated estuary. The estuary is in a highly modified condition as a result of substantial clearing within the catchment and is eutrophied and prone to fish kills.Covering a total area of 5.5km2, with the central basin having an area of 4.2km2 the inlet is fed with waters from the Pallinup River (Salt River). The inlet holds a volume of 6500000m3 and is enclosed by a 500m long sandbar that opens periodically at intervals of several years.
