"I've been growing wheat for 64 years and this is the best potential yield that I have ever seen," the Yarrabah farmer stated simply.

"It's very exciting but it's quite nerve wracking at the same time though, hoping everything goes right. It never usually does but we can only hope."

A small farming operation with himself, his son Geoff and one other worker with on-farm storage, he says he won't feel the pandemonium he expects other farmers in the region will come harvest time.

Their harvest is due to begin at the start of December.

He attributed the crop's success to decent rainfall at the right times, and to a well-rested plot of land.

A nice drop of 20mm of rain on Sunday certainly didn't go astray.

"The ground, it's been long fallow, and had a spell for three and a half years forced by the drought," Mr Barwick explained

"Then we've had incredible rain starting in January for this year which, the timing of which was absolutely perfect."

But as any farmer knows, a lot can happen in the meantime and can only hope it doesn't, even though past experience tells him otherwise.

"Something always seems to happens," he says, resigned.

"We still have a bit to go, still got to get past hail, fire, storms and grasshoppers and mice, further disease, but if we get past all that, it could be the best yield we've ever experienced."

He predicts this season will be "pandemonium" with a shortage of farm workers, a shortage of trucks to cart the grain to the silos, and a shortage of storage.

"It'll be hectic," he said.

"With crops like this ... there will be people with excess grain who have to store it on their own farm or do something else with it."

With the exciting yield potential looming, current prices as "reasonable" but Mr Harwick expects there to be a downturn as harvest hits full swing.

While covered for fire and hail, everything else is "in the lap of the gods" now.
