Revised crop estimate moves to 10.3mt

Although wintery August conditions have come too late for many growers across the WA grainbelt, a cool and wet September could push WA's crop to 11 million tonnes this harvest according to the Grains Industry Association of WA (GIWA).

The State's total crop production was revised up to 10.3 million tonnes in GIWA's September Crop Report, up just one per cent from its report last month, despite near average or better rainfall in August across most of the grainbelt.

However GIWA oilseeds council chairman and report author Michael Lamond said there was significant potential for that mark to be exceeded by up to 800,000 tonnes if favourable weather conditions unfolded throughout the rest of the month.

"We were pretty conservative with our estimate because we've still got September to go and on one hand the crops are later and they have got less potential, but on the other hand because they are later and we are now in a 'normal-ish' spring pattern, it's less likely to be smashed with frost like we did last year," Mr Lamond said.

"We could hit a total of 11mt total, a large proportion of that could be from wheat if we do get some rain and we don't get frosted in September."
