Emergency Services Agency commissioner Georgeina Whelan warned on Friday afternoon that the Adaminaby Complex fire could cross the ACT border on Friday night, but that did not eventuate.

The main fire front remained three kilometres from the territory on Saturday morning, and 40 kilometres from urban areas in the ACT.

An ACT strike team is supporting firefighters tackling the Adaminaby Complex fire, which had burnt 28,640 hectares as of Saturday morning, when conditions were easing across the fireground.

It was burning at "advice" level on Saturday morning, as were the Atkinson and Dunns Road fires, where conditions were also easing.

The Atkinson fire, which was 114 hectares in size, was burning 20 kilometres west of the ACT border and 45 kilometres from the territory's urban areas.

There were 620 firefighters and 128 vehicles tackling the massive Dunns Road fire, which had burnt through more than 316,000 hectares as of Saturday morning. It remained 18 kilometres away from the ACT and 48 kilometres from urban homes.

There is "a high chance" the Atkinson and Dunns Road fires could merge on Saturday, according to the Emergency Services Agency.

Canberrans were urged on Friday afternoon not to travel south into rural areas because of the risk of fire.
