Western Australia's main grain handler the CBH Group is anticipating a potential record crop this season of between 14 and 16 million tonnes.

That is in line with the Federal Government's science and economics research bureau ABARES forecast for WA of 15.5 million tonnes.

WA's record harvest was 15.9 million tonnes in season 2013/14.

Mick Daw is the acting general manager operations with CBH.

He said as each day passed the potential of a record harvest became more bankable.

"Growers have become extremely good at conserving moisture, so the fact there is moisture through most of the state paints a pretty good picture for us, although there are a few areas across the state that are probably a little too wet, but I guess it's a good problem to have at this time of the year."

Mr Daw said some farmers were speculating this season could be the really big one, with estimates around 20 million tonnes.

"I've definitely heard that," he said.

"Some of the early crops that we've seen are definitely impressive and there is potential for it to continue to grow on us."

Mr Daw said WA could be headed for a harvest to rival the 2013/2014 record result.

"Some of those years we haven't had the whole state perform at record levels and as we see it at the moment everybody is in a pretty good position to produce one of their biggest crops right across the state," he said.
