Wagga firefighters deployed to NSW will face catastrophic fire danger on Tuesday, with the state under a total fire ban on Monday and Tuesday.
Doctors and paramedics on the ground have treated more than 100 people hurt during devastating bushfires in NSW, including 20 firefighters.
Three people have died, and 150 homes have been lost as parts of NSW continue to burn.
NSW Fire and Rescue Superintendent Stewart Alexander said the next deployment is Tuesday.
"We've been changing people over every seven days for the last four weeks," he said.
"One day of travel, five days on the ground and one day of flying back.
"We can deploy far and wide, and we must support the locals up north to give them a break."
Superintendent Alexander said while helping their comrades in other parts of NSW, firefighters also remain in the Riverina to respond to any incidents.
"It is a big commitment by everyone as time away from family, time away from work and we have firies injured yesterday," he said.
"Our retained firefighters are just men and women who are doing their bit to help."
Superintendent Alexander said the catastrophic events are just one example of how well FRNSW and the Rural Fire Service work together.
"It's a seamless partnership, and we are always working closely whether its up there or here in our region," he said.
