The Green Wattle Creek fire to the north of the Wingecarribee has now burnt out more than 90,000 hectares of bushland and with the current drought conditions will not be contained for quite some time.
Fire crews spent part of the weekend carrying out backburning operations to protect a number of villages.
A community meeting at Mandemar was also well attended yesterday by residents around Wombeyan Caves Road who were keen to find out how the fire could affect them.
RFS Southern Highlands Inspector David Stimson says they're particularly concerned about the weather conditions for tomorrow, with temperatures forecast to hit 37 degrees.
Heavy machinery will be around the Colo Vale area from today to strengthen containment lines.
