GrainCorp general manager of operations Nigel Lotz said the season was looking so strong that they would need to hire another 40-or-so people at their Junee site to keep up with the surge in demand.

Mr Lotz said there was no shortage of applicants so far, saying that there were plenty of job seekers out there due to the economic turmoil caused by COVID-19.

"This is a great opportunity if you're going through a difficult period with your current job; what a great opportunity to come out to regional Australia [and] to Junee," Mr Lotz said.

"It's a great part of the world and you're participating in a fantastic part of Australian agribusiness, which is harvest - and getting paid for it, which is a bonus."

Mr Lotz said it was currently "flat out" at the Junee site, which is ramping up its capacity, trialling new equipment, and training their staff in the lead up to the harvest season.

Nutrien Ag Solutions branch manager Peter Dorsett said they too were experiencing an unprecedented boom in sales, as farmers prepare for a busy season ahead.

"I've been in Wagga for 29 years with the company and it would have to be one of the strongest sales years I've ever seen," Mr Dorsett said.

"It goes hand-in-hand with a really strong season and good commodity prices, so farmers have additional confidence."

Mr Dorsett said he had noticed customers coming in with more of a "spring in their step" after having weathered four years of drought.

He said the only lingering worry was the chance of late frost damaging the prematurely budding crops, but that otherwise all signs were pointing to a bumper harvest.

"We've had the perfect start from a seeding and sewing perspective with good rainfall in March through to May, where we've had the optimum moisture to put crops in," Mr Dorsett said.

"The season is shaping up to be one of the best springs we've had in years, which is a welcome reprieve."

The Bureau of Meteorology forecasts between 10 and 25 millimetres of rain will fall in and around Wagga in the next three days.
