A bad frost is expected to have caused significant damage to grain and grape crops in central-west New South Wales.
Temperatures on farms to the south-west of Cowra plummeted to minus 4.7 degrees early on Tuesday morning.
Elders agronomist Mark Hinderager says the full extent of damage won't be known until harvest in a few weeks' time.
"Yeah, this is a bad frost. (We were) especially not expecting a middle of October frost," he said.
"A bit pie in the sky right now, but probably a 40 to 50 per cent average (loss) with that kind of frost."
