This legislation establishes a comprehensive framework for the management, control, and prevention of specific plants and animals, primarily to safeguard agriculture and related resources. It empowers the designation of certain plants and animals as declared pests, assigning them categories that dictate required control measures such as eradication, population reduction, or prevention of spread. The framework also regulates their introduction, movement, and keeping, including the management of native declared animals through approved programs. Furthermore, it governs the safe storage, use, and transport of agricultural chemicals to prevent harm. Agricultural organizations are mandated to comply with specific control actions for declared pests, adhere to biosecurity protocols, and follow strict regulations for chemical handling, supported by powers of inspection and enforcement.
