  • It must not be given away, sold, or released into the environment without a permit.
  • The Act requires everyone to take all reasonable and practical steps to minimise the risks associated with invasive plants under their control. This is called a general biosecurity obligation (GBO).
  • At a local level, each local government must have a biosecurity plan that covers invasive plants in its area. This plan may include actions to be taken on yellow bells. Some of these actions may be required under local laws. Contact your local government for more information.
