Firefighters are taking advantage of milder conditions to carry out containment work on more than 80 blazes that continue to burn across NSW.
There are hopes that many of the hundreds of firefighters who have been working around the clock battling the state's bushfires will soon be able to return home to their families.
On Sunday evening 84 bushfires remained in NSW, of which eight were uncontained.
None were directly threatening properties. The fire danger has now been downgraded to low to moderate across the state.
The Rural Fire Service said the cooler conditions had given firefighters some respite.
"We are taking advantage of these cooler weather conditions to get some consolidation works done, constructing containment lines to ensure there's no flare up from winds forecast in the coming days," an RFS spokesman told AAP.
However, he warned that NSW would remain at risk of fire danger throughout the remainder of summer.
"It only has to have a few days of warm, dry, windy weather and those fire grounds will be susceptible to fire again."
More than 300 firefighters continue to battle an uncontained blaze in northwest NSW, where 53 homes were destroyed last week.
Light rain near Coonabarabran overnight has helped bring about a reduction in fire activity, in what has been the state's most destructive bushfire for more than a decade.
As well as the 53 homes, 113 outbuildings, livestock and farm machinery were lost in the fire, which has burnt through more than 54,000 hectares and has an 180km perimeter.
In the coming days, firefighters will scour the area in an attempt to eradicate any smouldering remnants that could reignite.
"They'll be looking at any tree logs or stumps in the area to extinguish and cut up to make sure they don't create any embers on a windy day, and cooling any hotspots near containment lines," the spokesman said.
"They'll be there for at least the coming days, if not the next week."
He said there were hopes that many firefighters would soon be able to return home to their families.
"Our main focus is to get these fire crews ... back to their normal lives, back to families, back to work."
A fire believed to have been started by lightning on Friday night is also continuing to burn behind containment lines in Ku-ring-gai National Park north of Sydney.
The RFS says walking access to the Basin, in Pittwater, is restricted and smoke can be seen as far away as the Central Coast.
All NSW fires were currently burning at an Advice level, the RFS spokesman said, which meant residents should remain vigilant.
