ERSKINE Park Rural Fire Service deputy captain Adam Quinn described the bushfires in the Blue Mountains as the worst he'd ever seen.
He's one of the thousands of firefighters who have put their lives on the line over the past fortnight.
"We have 28 active members here and virtually all of us has had to get time off work or be on night-time call," Mr Quinn said.
Firefighters have been posted to Muswellbrook, Springwood, Faulconbridge and Mount Victoria.
Volunteers at the Plumpton and Eastern Creek brigades have also been part of the effort.
"It's been daunting fighting these ferocious fires," Mr Quinn said.
"They moved so quickly and were unpredictable.
"Everyone has been on edge and feared for the worst.
"The Muswellbrook blaze had the potential to break containment lines.
"We haven't met many affected families but one of our former members who lives at Springwood lost everything so he was quite distraught."
The Erskine Park brigade was on stand-by for the Blue Mountains on Wednesday when it was feared conditions would worsen.
It didn't happen but firefighters still had their work cut out trying to get a grass fire under control at Archobold Road, Eastern Creek.
"We had six trucks there," Mr Quinn said.
Volunteers at the Plumpton and Eastern Creek brigades have also been part of the efforts.
The Erskine Park brigade has been grateful the support it has received from the community.
"Eagle Boys St Marys have been around several times with pizzas, noodles and bottles of water," Mr Quinn said.
