The second-round of volunteers from the south-west made their way to Gospers Mountain in New South Wales to help the ongoing fires stretching almost the entire east coast from Sydney to Brisbane.

Strike team leader Steve Lewis said it was a hard battle throughout the team's three-day deployment.

"The sheer heat and intensity of the fires is something I haven't seen in my 45 years," he said.

"It just explodes.

"It was initially a daunting prospect looking at the sheer volume of the task ahead.

"But doing the work in small increments and doing the best you can is the reality.

"We did a lot of close work with the fire front and safety is the single-most important factor."

As the fires continue to grow across the state, fire fighters from around Australia have flocked to help communities battle the blazes.

The team left last Thursday night and their roles demanded 5am wake-ups, heading to the blazes and working in communities and not getting shut-eye until 11pm.

"Their work consisted of asset protection as the fires pushed out over the area, line securing on dangerous edges, back-burning, large lining to secure fire spread, bottle direct and flanking attacks of fire advances," Mr Lewis said.

"The strike team also spent time alongside local families as fires went through their communities.

"This created a tangible calming affect for families."

After putting in 18-hour days of physical, emotional and psychological work, the CFA volunteers return home exhausted.

The team drove into Mortlake on this evening tremendously satisfied with their work.

"The fire area is over 100,000 hectares with a perimeter of over 300km and is still spreading," Mr Lewis said.

"We did a lot of heavy, hard work.

"Coming from the green of Warrnambool and stepping into that environment, it was surreal.

"As strike team leader I can say these people couldn't have done our districts more proud."

District Five is organising another strike team to leave later this week.
