Heavy rainfall across south-eastern New South Wales has both helped and hindered crews, the Rural Fire Service said.
It comes as blazes burning in the South Coast and the Snowy Mountains could be contained this week.
The RFS has welcomed the rain but the downpours have prevented some backburning operations and some crews from fighting fires on the ground.
The Dunns Road fire which caused considerable damage in Batlow and Tumbarumba earlier this month has received about 25 millimetres of rainfall on Monday, NSW RFS public liaison officer Peter Jones.
"[Rainfall] has helped however as a result of the weather we've had to pull the crews out and they can't remain on the fire ground in these sorts of conditions as it's too slippery," he said.
While crews have been unable to work on the fireground on Monday, Mr Jones said he was confident enough had been done to contain the blaze but this was not yet confirmed.
"There are still some hotspots but we are expected for more rain this afternoon, at this stage the fire is deemed as being controlled," he said.
"There will be a reassessment in the next 24 hours."
Activity also decreased on other fires burning west of the ACT, including the Mary's Hill and the Adaminaby Complex fires over the weekend, the ACT Emergency Services said.
At the NSW South Coast, the more than 300,000-hectare Currowan fire was labelled as "being controlled" on Monday.
NSW RFS operations officer Marc Donnelly said the ground had experienced "pretty big rainfall" on Monday.
"At this stage it hasn't been a hindrance, we have modified operational conditions to ensure the area is still safe for us to operate in and the rainfall is certainly welcome," he said.
The rain could see backburns postponed.
The main area of focus for the fire was north-west of Kangaroo Valley.
Mr Donnelly said he was confident, if current weather conditions persisted, the fire could be contained within the week.
The Clyde Mountain fire, on the southern flank of the Currowan blaze, is being controlled with the possibility of backburns postponed due to rainfall.
The Charleys Forest fire, on the western flank of the Currowan blaze, is under control.
On the far South Coast, the Badja Forest Road fire is being controlled and light rainfall was forecast for the fireground on Monday.
