Agriculture Minister Dugald Saunders said this had been one of the most challenging years on record for farmers in the Northern Rivers and flood impacted areas of NSW.
"The persistent wet weather has made it harder for farmers to get back into paddocks, sow crops, feed livestock and start rebuilding," Mr Saunders said.
Primary producers recovering from the devastating impacts of floods are eligible to access the special disaster grants of up to $75,000.
Under the grant, primary producers will receive $15,000 upfront to get going, without the need for documentation. There is also a landowner grant of up to $25,000 for smaller landholders.
