General Biosecurity Duty

All plants are regulated with a general biosecurity duty to prevent, eliminate or minimise any biosecurity risk they may pose. Any person who deals with any plant, who knows (or ought to know) of any biosecurity risk, has a duty to ensure the risk is prevented, eliminated or minimised, so far as is reasonably practicable.


Cut the vines close to the ground and dig out as much of the root system as possible. The remaining vines in trees can either be removed or left to rot.
