Legal requirements
- Broad-leaf privet is a category 3 restricted invasive plant under the Biosecurity Act 2014.
- You must not be give away, sell, or release into the environment. Penalties may apply.
- You must take all reasonable and practical measures to minimise the biosecurity risks associated with dealing with broad-leaf privet under your control. This is called a general biosecurity obligation (GBO).
- At a local level, each local government agency must have a biosecurity plan that covers invasive plants and animals in its area. This plan may include actions to be taken on broad-leaf privet. Some of these actions may be required under local laws. Contact your local council for more information.
