Wash House Beach is one of the most diverse rock platforms in NSW. In 2008, a study was undertaken by Dr Debbie Geronomi and a team of four Year 12 students from Camden Haven High School. The study identified and measured some 128 species of organisms living on the platform. An interpretative sign was unveiled by the Federal Member for Lyne, Rob Oakeshott, on Friday 14th November 2008.
The rocks of the Wash House Beach Rock Platform form part of the eastern extent of the geological feature known as the Lorne Basin. For more information on the geology of the Lorne Basin, please click here.
