The bushfire burning near Braidwood for more than a week has been contained, the RFS says.
The North Black Range fire began in Tallaganda National Park in late November and has burnt almost 37,000 hectares.
The NSW Rural Fire Service said on Friday afternoon the fire was now contained.
Deputy incident controller Cameron Leary said the cause of the fire was suspected to be lightning but this would be confirmed over coming days. Final figures regarding property losses would also be confirmed.
"Our volunteer firefighters and supporting agencies have done a tremendous job under some very trying conditions," he said.
Fire crews will continue to work for several weeks to consolidate containment lines and continue to extinguish the fire.
Kings Highway has also been reopened after the South Coast fire forced its closure.
Fire crews have been conducting significant backburning and clean-up operations along the length of the thoroughfare over the last couple of days, as "benign" weather allows them to recoup and mitigate fire risks.
The highway was opened between Braidwood and Nelligen on Friday afternoon. Its remaining stretches, between Queanbeyan and Braidwood and Nelligen and Batemans Bay, weren't subject to closure.
NSW Rural Fire Service public liaison officer, Phil Paterson, said fire crews - including aircraft - had honed in on some areas of vegetation near the highway, including at the intersection of Western Distributor Road.
"It's about trying to restrict the fire running up a couple of slopes towards the highway," Mr Paterson said.
"[Another] backburning operation has been conducted at the intersection of River Road and the Kings Highway."
The South Coast's Currowan fire was continuing to progress in a northerly direction but also remained at advice level.
Crews were continuing to construct hard containment lines along its eastern and western sides, using equipment including bulldozers. Morton National Park, southeast of Goulburn, would remain closed until further notice.
"We can't effectively attack the fire within the national park just because of the [nature of the] country," Mr Paterson said.
Building impact assessment crews had been deployed to work on both the North Black Range and Currowan fire grounds, Mr Paterson said. Their job was to ascertain what assets people had lost or had damaged in each fire.
"It's about actually ascertaining what has been lost, but it's also about gaining data that we can use for research purposes to help us manage fires in the future," Mr Paterson said.
"It's really critical stuff."
South Coast fire crews expected riskier conditions on Sunday, with temperatures expected to get past 30 degrees, Mr Paterson said. Conditions were expected to be more benign again early next week, before elevated temperatures on Thursday and Friday.
