"This situation across parts of the grainbelt in NSW and Queensland is still playing out and unfortunately many farmers won't know the extent of the damage until waters recede. With more rain forecast for later in the week, the recovery process may be some time off," Simson said.

She said the NFF joined NSW Farmers in welcoming disaster assistance made available by state and federal governments last week.

"I urge farmers to explore what financial help is available to assit with recovery. We expect that all levels of Government will act with urgency to repair damaged infrastructure. The last thing farmers need is further delays to harvest because roads and bridges are closed or no longer able to handle heavy machinery."

Simson said most importantly, she implored those affected to take care of their mental health and wellbeing and to check in on those around them, during these uncertain times.

"This unfolding event is causing significant angst for farming families, many who were underway or preparing to harvest a bumper grain crop.

"This is yet another period of time when Mother Nature is challenging our rural communities. There's no doubt farmers are resilient and part of being resilient is recognising when help is needed and seeking that help.

"I'd encourage farmers to take the time to take stock of their own mental health and consider that of their nearest and dearest and others in their community."
