And while this season has been kind to growers, the threat of importing diseased produce poses a high risk to growers' operations.

Apple growers are being extra cautious when monitoring their crops for any signs of threatening diseases such as fireblight, European canker and apple leaf curling midge.

In an attempt to decrease the risk of contracting any disease brought into Australia, growers such as NSW Farmers' Orange Branch Horticultural Committee chair Peter West have continued monitoring closely while also following some NSW Department of Primary Industry biosecurity awareness measures.

On his 150-acre orchard, Mr West said he had not dramatically changed the level or method used to monitor pests and diseases on his property.

"I dare say if we see anything different on trees we are very wary. It's something we have never seen before," Mr West said.

From industry biosecurity awareness workshops conducted by the NSW DPI Mr West said he gained extra information that previously hadn't been available.

"Our climate is very suitable (to the diseases), especially to fireblight in some of the growing regions apparently," he said.

The workshops also provided grower packages which included posters that could be displayed on the property to boost familiarity about the diseases.

NSW DPI strategy leader for plant health Dr Kathy Gott said there were three main components to their apple industry biosecurity awareness initiative; being aware, being prepared and taking action.

"Learning and knowing about it (is the first step)," she said. "The second step is taking action against those risks. It might be at the farm gate. One of the things we have been encouraging growers to do is know what's coming onto their property."

Dr Gott said it was important to get advice immediately if something different was noticed.

The Exotic Plant Pest Hotline (1800 084 881) is a toll free service with expert advice to help protect the industry.
