It was a wait and watch, as the fire had potential to possibly encroach on the Jerrabomberra Creek jurisdiction of Royalla, Little Burra, Mount Campbell and Fernleigh Park.

The fire spread prediction map showed fire coming through the area but crews remained confident this would not happen, and it didn't.

NSW RFS Jerrabomberra Creek captain Brad Griffin said although there was no threat to Royalla he was on a "heightened state of alert".

Mr Griffin said his main concern was if the fire hit the Tinderry ranges, which haven't burnt in about 50 years. He said crews would be fighting the fire for weeks if that were to happen.

Earlier on Saturday, a strike team from Burra RFS was sent out to the Clear Range fire to help with patrolling.

Out-of-area strike teams stationed throughout the firegrounds meant Queanbeyan RFS brigades had kept their focus on in their own area.

Queanbeyan City RFS brigade captain Nick Hornbuckle said firefighters always wanted to go in when a fire started, but it was a good sign when his team was not immediately needed.

"When it does happen, it's game-on. Everyone's out the door to go and do it. Again, given the current fire season, it's been nice to sit in the air-con and watch TV and not have to do things sometimes," Mr Hornbuckle said.

"Either way it goes, I don't think anyone will be disappointed if that makes sense. If we get to go and help, we get to go and help. If we sit here and do nothing, that's good. Then it hasn't been as bad as we thought."

Mr Hornbuckle said the long fire season had taken its toll on firefighters.

"It's not just the days of massive fire, flames crowning through the trees. The longest period is the mop up after that, establishing containment lines, all that sort of stuff," he said.

"It's long hard work and people are really getting tired. It causes a bit of stress, less so much dealing with the actual fire and fighting the fire, but it's the stress on family, the stress on work, trying to balance that all out.

"Traditionally you could take a few days here and there, it's not too much of a problem. Now it's becoming a constant, and you're overloaded with a lot of things at the moment, hoping for a break."

The unprecedented conditions have also led to shifts in how firefighters tackle blazes.

Mr Hornbuckle said there had been discussions about new tactics and how to approach the task, with a focus on bold efforts to contain fires.

"This season, funnily enough, we've actually used less water in the truck than [we] have most seasons. That sounds odd because it's been such a busy season," he said.

"It's because the fire's been so intense that we can't do anything with it. So you're basically looking after yourself. Using a little bit of water, protect the house and move to the next one, the next one and the next one."
