Cooler weather has brought relief to firefighters in NSW's south, but hot and windy conditions in the state's north are opening up new areas of severe fire danger.
Fire crews were dealing with 141 fires across the state, 31 of them uncontained, at 9.30am (AEDT) on Wednesday.
Since Tuesday, the fires have burnt through more than 131,000 hectares but on one of NSW's worst ever fire danger days, only one home is believed to have been lost at Jugiong, near the ACT border.
Around 1700 firefighters worked through the night to put in containment lines.
They were assisted in the state's south by a southerly change bringing cooler conditions.

The cool reprieve is expected to only be short-lived however, with temperatures forecast to climb again by the end of the week.
"We don't need new fires today," Rural Fire Service (RFS) Deputy Commissioner Rob Rogers said on Wednesday morning.
He said the cooler change in the southern part of the state meant numerous fires there were not burning so aggressively but firefighters still had a lot of work to do.
"Of equal concern is the severe fire danger in the Hunter and all the way up to the Queensland border and all the way out to the Moree area," he told ABC Radio.
"It's far from over ... we're dealing with a whole lot of new fire danger that we didn't have yesterday.
On Wednesday morning the RFS had five watch and act alerts in place with the Cobbler Road fire near Yass of most concern.
It burnt through around 16,000 hectares overnight and it's feared stock losses may be in the thousands along with fencing losses.
Fire crews are protecting remote rural properties in the area as the fire approaches.
