A significant hazard reduction burn north of the Illawarra that started on Saturday, September 9, is spreading smoke across greater Sydney.
The 2692 hectare burn in bushland at the Holsworthy Military Barracks will run until Thursday.
Traffic on Heathcote Road is affected.
Strong winds and overnight rain have postponed a planned 2692 hectare hazard reduction burn that was to take place in bushland at Holsworthy Military Barracks, off Heathcote Road, from Friday to Sunday.
Around 40 fire trucks, including from outside the Illawarra, had been organised to conduct the burn, NSW Rural Fire Service Illawarra district coordinator David Hitchens said.
"It's frustrating, a lot of planning goes into these," he said. "We'll reassess later today to possibly light up in the morning."
A significant three-day hazard reduction burn north of the Illawarra may lead to smoke spreading across greater Sydney.
The 2692 hectare burn in bushland at the Holsworthy Military Barracks, will start around 12pm on Friday, September 8, after overnight rain forced its delay by a few hours.
The burn is expected to run until Sunday afternoon.
This particular area has not had any fire in the landscape for more than 20 years, Illawarra RFS acting zone manager David Bartlett said.
"As history dictates, wildfires that come from the western side of the Sutherland Shire pose serious risks to the community, so this hazard reduction burn will lower the risk to the Engadine, Barden Ridge, Heathcote and surrounding areas, giving firefighters a strategic advantage, Illawarra RFS crews said.
The hazard reduction burn will take place to the west of Heathcote Road and smoke may force the partial closure of this road during some periods, Mr Bartlett said.
The HR will span three local government areas - Sutherland Shire, Campbelltown and Liverpool.
"Crews [are] working on rotating 12-hour shifts to ensure the hazard reduction burn is adequately resourced," the RFS said.
"A further three days of patrols will be conducted at regular intervals or until declared out."
Due to the size of the hazard reduction burn, smoke will likely affect all of the Greater Sydney area for a number of days.
Always call triple-0 if you seen an unattended fire.
