Following earlier reports by the ABC, the RFS confirmed four volunteer fire fighters were involved in a truck rollover while defending properties in Jennings, but all have come through uninjured.

"For that rollover there were four crew involved, three were transported to Tenterfield Hospital for observation overnight, but they've since been released," An RFS spokesperson said.

RFS is now providing support to those crew members, but the spokesperson said fellow volunteers were relieved that the volunteers onboard the truck were unharmed.

Queensland Emergency Services have reported the loss of homes in the nearby Wallangarra.

The RFS spokesperson said there were "unconfirmed reports" of property losses in Jennings and in the surrounding fires, but they could not be confirmed until conditions ease and assessment crews can access the firegrounds.

"We only have unconfirmed reports at this stage - hopefully as conditions ease we'll be able to get ground crews and evaluation teams into those areas to really assess the impact," the spokesperson said.

A wind shift was expected around 9pm on October 31 that fire crews predicted would blow fire fronts back on themselves and fire conditions have eased overnight.

"What we really saw last night was a southerly change and that did see an increase in the northern flanks late into the night - which maintained those emergency warning levels into the night," the spokesperson said.

"However, today that does a bring a slight easing of conditions.

"It still will be challenging, we're trying to take advantage of the milder conditions this morning, but the forecast is still for a high fire danger day and that activity will pick up again by this afternoon."

The spokesperson said a forecast of cooler conditions and potential rain later in the week was a boon and the RFS was aiming to rally its efforts through the next few days before conditions heat up again next week.

"We'll be trying to bolster resources into the area in the next few days ahead of the next warm period moving into next week," the spokesperson said.
