Broke Inlet is a pristine, large estuary located within D'Entrecasteaux National Park, approximately 40 kilometers west-northwest of Walpole. It is the only major estuary in the South-West region that has not been significantly altered by development along its shores or within its catchment. The inlet is fed by the Shannon and Inlet rivers, and its waters are nearly fresh until the sand bar at the mouth breaks, allowing Southern Ocean seawater to flow in. It is connected to the ocean by a narrow, seasonally open channel that cuts through high ridges of sand dunes. The area is a haven for birdlife, including pelicans, cormorants, and hooded plovers along the beaches. The landscape is characterized by sheltered waters, sandy shores, and surrounding dunes, offering a remote and natural fishing environment.
