Plant pests and diseases
Australia is lucky to be free from many of the world’s most damaging plant pests.
Exotic plant pests are capable of damaging our natural environment, destroying our food production and agriculture industries, and some could change our way of life.
Australia’s biosecurity system helps protect us from exotic plant pests.
The Department of Agriculture and Water Resources manages this system with state and territory governments, industry and the community.
Find out what you can do to:
- identify destructive plant pests and diseases
- stop unwanted and destructive plant pests and diseases getting into Australia
- report any signs of pests and diseases that you find.
National priority plant pests
The Plant Health Committee has identified national priority plant pests that are exotic to Australia, under eradication or have limited distribution. These are the focus of government investment and action, including funding through the Agricultural Competiveness White Paper to improve biosecurity surveillance and analysis. While by no means the only plant pests of biosecurity concern, the National Priority Plant Pests serve to highlight the sort of threats Australia faces.
Find out more about the Top 40 unwanted plant pests in this short video with Australia’s Chief Plant Protection Officer.

Stop plant pests and diseases coming to Australia
Travelling or mailing to Australia
All travellers arriving in Australia need to be aware of our biosecurity requirements. This includes completing your Incoming Passenger Card honestly, and declaring any items that could pose a biosecurity risk, including live animals and plants, animal products, plant material, and certain foods.
Before you travel, check what you can and can’t bring into Australia.
Check out the priority plant pests on this page to see how you can avoid these stowaways in your luggage.
When sending mail to Australia, accurately declare the contents of your package on the postal declaration label.
If you are moving to Australia you need to be vigilant for insects, bees, ants, plant material and soil when packing up your household goods. When you unpack always check again for pests or signs of their activity such as borer holes and frass in wooden items.
We all like a bit of online shopping but if you are purchasing goods from overseas, especially seeds, wooden items or goods made from organic materials, or unusual pets, you need to check whether it can legally come into Australia.
Many plant pests are capable of hiding in imported goods. Some pests can remain dormant in an item for years, and not emerge until environmental conditions are right.
Before you place your order check what can and can’t come into Australia. Some items may require an import permit.
Use the links above to find out more about the pests that have the potential to arrive in your mail.
Importing and shipping
Whether you are a stevedore, shipping agent, truck driver or a retailer selling imported goods- this puts you on the front line of defence against exotic pest incursions.
Many of our priority plant pests hitchhike their way to Australia with imported goods or attached to plant material, vessels, shipping containers and machinery.
You should always be vigilant to insects, bees, ants, soil and plant matter, as well as signs of pest activity such as borer holes in wooden items. This also applies to people moving their household goods to Australia.Use the pest links above to know what these pests look like, the time of year you’re likely to see them, and how to report any detections.
Farming and home gardening
As a grower or farmer your business relies on being pest and disease free. If you import plants, seeds and machinery, you need to be aware of, and comply with import requirements. This also applies to home gardeners and hobby farmers.Good biosecurity practices help protect your property from the entry and spread of pests and diseases.
