Still image of a Spotted wobbegong (Orectolobus maculatus) taken during underwater visual census surveys in the Cod Grounds Marine Park in New South Wales Commonwealth Waters of Australia in 2009 as part of the Reef Life Survey program. This volunteer network of highly trained divers is a product of the CERF Major Projects funding that facilitated a cost-effective citizen science contribution to inventory and monitoring of shallow water marine environments. The RLS program has been further facilitated within the NERP Hub, describing biodiversity patterns at a national and global scale, as well as providing critical baseline data from areas such as the Coral Sea Marine Park, from Ashmore Reef, the Great Barrier Reef,and other Australian Marine Parks such as the Cod Grounds.
