Sydney Metropolitan Catchment Management Authority (SMCMA) is a NSW Government agency with the aim of providing the community of Sydney with the knowledge and skill to achieve healthy waterways and bushland that all Sydneysiders can enjoy, now and in the future. It covers the surface water catchments of Sydney Harbour (and Parramatta River), Botany Bay (including Georges and Cooks Rivers), the Hacking River and northern and eastern beaches. This is approximatly three quarters of the Sydney Metropolitan area. The Catchment Management Authorities Act 2003 identifies the generic functions of the NSW CMAs, which include developing Catchment Action Plans (CAPs). Investment Priority Areas include improved river health including stable and healthy riparian areas and protection of biodiversity values, improving the extent, quality and connectivity of native terrestrial and aquatic habitats. The Threatened Species Demonstration Sites project aims to demonstrate best practice for the conservation of 11 priority threatened species, populations and communities. One of the sites is the Cabramatta Creek Flying-Fox Reserve which, with partners Fairfield and Liverpool Councils, demonstrates best practice in the management of the Grey-headed Flying-fox. The restoration of the Cabramatta Creek Flying-fox Reserve exemplifies how the SMCMA is leading the way to recover Sydney's biodiversity.
