South Canberra residents may see smoke curling up from south-western corner of the Brindabellas this week as a 2700-hectare hazard reduction burn takes place.
The burn in the north-eastern corner of Kosciuszko National Park started on Monday, and is one of 27 scheduled this autumn, taking in more than 32,000 hectares.
National Parks and Wildlife Service regional manager Mick Pettitt said the burn in the vicinity of Black Bottle Hill is expected to put up "quite a lot" of smoke due to its size.
He said its strategic location would help reduce the risk of bushfire coming into summer.
"With the forecast wind direction, there may be some smoke visible in the southern end of the ACT. The winds forecast are quite light, so there is likely to be some smoke lingering in the Brindabella Valley for a couple of days," Mr Pettitt said.
"The typical weather experienced in this area in autumn is ideal for our burning program because of the more stable atmospheric conditions, and cooler more moist evenings, which enable us to burn at much lower fire intensities than would be experienced in summer."
