Key points:
- A fourth person has died in the bushfires which have ravaged regions of New South Wales
- The man's remains were discovered in bushland on the southern end of the Kyuna Track at Willawarrin
- His death follows that of Julie Fletcher, 63, who died in the town of Johns River, and Wytaliba locals Vivian Chaplain, 69, and the elderly George Nole.
- Fires continue to cause headaches for crews with an Emergency Warning active for an out-of-control fire burning at Myall Creed Road at Bora Ridge, south of Ballina.
Police have confirmed a fourth person has died in the NSW bushfires after the discovery of a man's body in burnt-out bushland near Kempsey.
The victim is believed to be a 58-year-old man who lived nearby in a shed, but who had not been seen since Friday.
His remains were discovered in bushland on the southern end of the Kyuna Track at Willawarrin shortly before midnight on Wednesday.
The discovery comes as better weather conditions around the state fail to make a dent on "aggressive fire behaviour".
More than 55 fires continue to burn around NSW on Thursday morning, with 24 uncontained and eight currently at 'watch and act' level. An emergency warning is currently active for a fire burning at Myall Creed Road at Bora Ridge, south of Ballina.
A total fire ban declared for NSW earlier this week has now lapsed.

His death follows that of Julie Fletcher, 63, who died in the town of Johns River, and Wytaliba locals Vivian Chaplain, 69, and the elderly George Nole.
Rural Fire Service NSW Deputy Commissioner Rob Rogers said the passing of Tuesday's "catastrophic" fire warning day had not made battling blazes easier.
"We had a better day yesterday, only one fire got to emergency warning, but even in these pretty benign conditions we're seeing quite a lot of aggressive fire behaviour simply because it's so dry," Mr Rogers told the Seven Network.
"Conditions starting to warm up tomorrow, into the weekend and then heating up early next week, a return to more gusty conditions. We're in for the long haul."
The RFS has confirmed more than 300 homes have been destroyed or damaged since Friday, at least 50 of them on Tuesday.
Mr Rogers said fires in the mid-north coast areas such as Taree, Port Macquarie, Kempsey and Coffs Harbour were proving hard to control, as well as a blaze near Lithgow in the Blue Mountains.
More than 800 firefighters remain in the field to protect properties and establish containment lines ahead of worsening conditions later this week.

Additionally, police responding to a trapped paraglider north of Wollongong on Wednesday arrested a man allegedly starting a fire in nearby bushland.
Officers found the Balgownie fire while helping the paraglider, and allegedly saw the 20-year-old man fanning its flames.
He has been arrested and charged with causing fire and will appear at Wollongong Local Court on 3 December.
The fire was quickly put out but destroyed about 150 square metres of the bush.
Mr Rogers, meanwhile, defended a Sydney CBD fireworks display on Wednesday night while the statewide total fire ban was in force, saying it had been inspected and declared safe by authorities.
