The Badja Forest Road fire, which was at “emergency warning” level for most of Thursday, is now more than 260,000 hectares in size.
Police say inquiries are continuing and no further information is available at this time.
The discovery marks the 25th person lost in NSW since the start of the fire season.
On Thursday, flight engineer Rick DeMorgan, captain Ian McBeth and first officer Paul Hudson died as their Lockheed C-130 Hercules aircraft crashed fighting an out-of-control blaze in the Snowy Monaro region.
Later on Thursday, six RFS volunteers avoided serious injuries after their tanker rolled off the Princes Highway near Mogo, and down an embankment.
Each firefighter was able to remove themselves from the vehicle, and they were treated at the scene by paramedics, before being taken to hospital for treatment to non-life-threatening injuries, including neck pain, back pain and lacerations.
After the mid-north, the Hawkesbury and Blue Mountains areas were devastated by fires earlier in the season, it was only in December when the south truly felt the devastation of the bushfires in the area.
Thousands of homes have been destroyed and the majority of the state’s fire-related deaths occurring in the Snowy Monaro and South Coast regions.
The total fire damage across NSW is estimated to be upwards of 6 million hectares.
