Pests and diseases
There is an enormous range of pests, diseases and weeds which can affect plant industries in Australia. Some are already present in Australia and may be confined to small areas of the country; others are yet to arrive on our shores.
Either way, once present they can spread from one part of Australia to another through the movement of fruit, vegetables, plants, flowers, plant products and soil.
The introduction of a pest, disease or weed into a production area can result in expensive controls being implemented and in a loss of markets, which can cost industries and the community millions of dollars.
If you notice any unusual plant pest or diseases symptoms on your travels, please report it as soon as possible. What you have found could be exotic and potentially damaging to that state or territory or to Australia.
