The Flora and Fauna Guarantee Act 1988, also known as the FFG Act, is an act of the Victorian Parliament designed to protect species, genetic material and habitats, to prevent extinction and allow maximum genetic diversity within the Australian state of Victoria for perpetuity. It was the first Australian legislation to deal with such issues. It enables the listing of threatened species and communities and threats to native species, and the declaration of critical habitat necessary for the survival of native plants and animals.
After an extensive review of the Act in 2019, the Flora and Fauna Guarantee Amendment Act 2019 modernised and strengthened the provisions of the Act on 1 June 2020. Enforcement of the FFG Act is overseen by the Office of the Conservation Regulator (OCR).
