More than 1,000 firefighters were deployed to battle the fires, many of which are at Emergency Warning status because of "erratic fire behaviour and threats to homes", according to the NSW Rural Fire Service.
Several people are still unaccounted for and 30 more have been injured - mostly firefighters working for hours on end in smoky, smouldering scrubland and blazing forests of towering eucalyptus. She was in an absolute panic. "There's fire everywhere. I need the boys here now, '" Harwood said of their final phone call.
"We are so impacted by drought and the lack of rain", she told AAP on Saturday. "That's when me and bub got out of there, but my partner's parents stayed back to try and protect the house and animals". "I tried so many times", Harwood added.
Mrs Harwood paid tribute to her "amazing and strong" mother-in-law, who moved to Wytaliba to live a sustainable life on her "own little piece of land".
In tributes posted to Facebook, neighbours and friends described Mr Nole as creative and eccentric.
While they aren't trained firefighters they could help create firebreaks away from the front or provide accommodation and logistical support, Morrison told reporters. "We rang a friend who was in Wytaliba and he pushed through the fire to get to her".
She was found about 7pm on Friday after a blaze ripped through her property in Diehard, near Glen Innes, unconscious and suffering horrific burns over 40 to 50 per cent of her body. The local man's name has not been released.
It is understood the grandmother-of-six died in hospital on Saturday morning after being found with severe burns.
That victim died in a fire hundreds of kilometers (miles) from Glen Innes.
Conditions remained unpredictable on Sunday with most residents advised it was still too unsafe to return home.
More than 30 people have been injured, a lot of them firefighters. A spokesperson, Paul Turner, said they are in supervisor and adviser roles, and one is a liaison officer.
"At this stage, it appears at least 100 homes have been destroyed in yesterday's bush fires", the fire service said in an update early Saturday.
At least 150 homes have been destroyed across fires in NSW and authorities have warned communities the devastation is likely to worsen over coming days.
Wildfires have also been reported in the neighboring state of Queensland.
Prime Minister Scott Morrison said a large number of fires was incredibly concerning. His warning came before the third victim was confirmed.
"Scary stuff", says Australian Matt Hope after flying above the NSW bushfires.
"Last night you could see the sky was a red and orange, amber color", he said. "We've got winds blowing, they're circling, it's like a cyclone".
At one point on Friday, 17 emergency-level fires were burning simultaneously across NSW.
His next-door neighbours were not so lucky, however - their home went up in flames Saturday afternoon.
The annual Australian fire season which peaks during the Southern Hemisphere summer has started early after an unusually warm and dry winter.
