Marine debris is a threat to marine life. The SWCC region has four distinctive coastal areas with differing conditions and sources affecting marine debris. The long stretches of sandy beaches between Leschenault Inlet to the Myalup desalination plant records the highest abundance of marine debris within the region. Winter storms drive offshore debris into these beaches and summertime recreational activities produce some littering.
