Identify priority plant pests and diseases

We have identified a group of priority exotic and unwanted plant pests and diseases. These pose the greatest risk to our industries and environment.

Explore our advice on these plant pests and diseases. See more about:

  • how to keep these pests and diseases out of Australia
  • where they come from
  • how to stop the spread if they are already here.

Each of these plant pests and diseases are in our list of National Priority Plant Pests.
