HUNTER bushfires remain at Advice level on Wednesday morning after several emergency warnings in catastrophic conditions on Tuesday.
Firefighters had brought the blazes to heel overnight after they threatened several homes.
That compares with three lives lost and 950 firefighters on front lines across the state.
The NSW Rural Fire Service said early reports indicated at least 50 homes had been damaged or destroyed.
Nineteen fires reached the emergency alert level, with 16 at once at the peak of the day, and more than 1.1 million hectares have already been burned.
More than a dozen firefighters suffered injuries on Tuesday across the state, NSW RFS Commissioner Shane Fitzsimmons said on Wednesday, but none were life-threatening.
Mr Fitzsimmons said smoke in parts of the state had acted as an insulator, reducing the duration of catastrophic conditions.
Despite that slight advantage, Mr Fitzsimmons said volatility and turbulence had forced the "extraordinary tool" or water-bombing aircraft to be grounded from time to time.
"Pleasingly, no-one has sustained life-threatening injuries .. and we've got no people unaccounted for," Mr Fitzsimmons said early Wednesday morning.
He said fire conditions had improved for Wednesday, but there was still an "enormous amount of hectares of fires burning".
"It's going to be a long effort yet, many days, many weeks and indeed many months if we don't get rain before we properly bring these fires under control, establish consolidation and declare them safe," Mr Fitzsimmons said.
"That's where we're up to at the moment.
"Conditions are easing, but there's a mountain of work ahead of us."
Premier Gladys Berejiklian said she was relieved that the state had "withstood the catastrophic conditions" and paid tribute to firefighters' efforts as a "great example of wonderful teamwork".
"Whilst we are not over the threat yet, we are through what was yesterday catastrophic weather conditions," she said.
"Unfortunately what we experienced yesterday is becoming a more frequent occurrence ... we haven't yet hit summer.
"The fact that no-one lost their life yesterday is truly amazing.
