A small-town firefighter has written a powerful letter calling on Scott Morrison to acknowledge the impact of climate change and take urgent action.

Christopher Nicholls, from Merimbula on the south coast of New South Wales, urged the Prime Minister to stop offering 'prayers and thoughts from Hillsong' and start treating the devastating bushfires 'like a war'.

'This is a national emergency, not a minor weather event,' he wrote.

Mr Nicholls described the terrifying experience of fighting a bushfire and said he often feared he would perish in a blaze and never see his loved ones again.

The firefighter said he was not impressed with the 'platitutes and cricket news' from Mr Morrison, describing his 'thoughts and prayers' as a 'pathetic response.'

Mr Nicholls urged Mr Morrison to treat the bushfire emergency as if a war had been waged on Australia.

'The war is climate change, and the battles are fires, drought, intense weather events such as tropical cyclones and other climate related phenomenon in the new normal of the climate-changed world,' he wrote.

'The war is the long game - and will be fought over several decades into the future, so there needs to be planning and task forces and armies and technology and considerable ingenuity.'

He also urged the federal government to show the Australian people they cared by 'mobilising and doing something about the bushfires'.

The heartfelt message was published as bush fires continue to rage across the state and the climate crisis continues.

The Rural Fire Service, meanwhile, has confirmed more than 720 homes have been destroyed over the fire season.

Water restrictions were also raised to a level two on Tuesday across Sydney, meaning the use of a hose is off-limits to all residents as dam levels continue to drop.
