Four firefighters have been injured while battling a blaze on NSW's mid north coast after their tanker rolled over.
The crew was working on a fire in Caparra near Taree on Wednesday night when the truck rolled down a hill, the NSW Rural Fire Service said.
The quartet was taken to the hospital, one of them with suspected spinal injuries.
Firefighters are hoping to gain the upper hand on several out-of-control bushfires burning across NSW as winds die down and conditions ease.
Nearly 80 fires continue to burn along the Great Dividing Range from the Queensland border to Victoria, with 32 still uncontained.
Blazes on the NSW south coast at Mount Kingiman and North Nowra, which threatened homes on Wednesday, have been downgraded amid cooler and calmer conditions but hundreds of firefighters remain on scene.
"Although there's no threat to properties, we do have fire crews working with local residents and landowners to deal with the fires as they approach," NSW Rural Fire Service spokesman Chris Garlick told AAP.
Concerns remain for the state's north, however, with a very high fire danger predicted on Thursday for the New England, Northern Slopes and Far North Coast regions - including near Grafton and Lismore.
NSW RFS Commissioner Shane Fitzsimmons was confident the firefighters would gain the upper hand on the most troublesome blazes, but winds of up to 60km/h were still going to be problematic.
"The conditions are pretty well stacked against them in terms of just how dry it is and how windy it is but it's obviously better than it was yesterday," he told the ABC on Thursday.
"We're shaping up for another front and increase in fire risk as we head into the weekend."
A total fire ban was issued for Sydney, the Illawarra and Hunter regions on Wednesday - something not seen so early in the season in nearly a decade.

Mr Fitzsimmons said the drought was having an enormous impact.
"In my time I don't recall quite as many fires and the length and breadth of the fires," he said.
"It's shaping up to be a long fire season if we don't get any drought-breaking rain."
