Casey Addison (Tomerong RFS), Leroy Lidbetter (Cudmirrah Berrara RFS), Brett Thomas (Callala Bay RFS) and Amanda Saxton (Cambewarra RFS) were among 1000 RFS volunteers to be given tickets to the fundraising concert which raised more than $9.5 million.

Even more special, all four ended up on stage during legendary Aussie performer John Farnham's concert ending song You're The Voice.

The quartet shared the stage with fellow Australian entertainment royalty Olivia Newton-John and Queen guitarist Brian May.

Casey Addison, the senior deputy captain of the Tomerong Brigade, is also the sales and marketing manager at Nowchem described the event as a "magical experience".

"It was incredible to watch everyone come together for the cause," he said "just unbelievable.

"I never thought in a million years I'd ever get to an event like this and then to be on stage with the likes of John Farnham, Olivia Newton-John and Brian May...Wow.

"It was special. We caught up with them and host Celeste Barber backstage and chatted and they thanked us for all the work we did during the fires.

"Just phenomenal. And the crowd was so supportive."

He admitted 2019 and the start of 2020 had been incredible times.

Casey spent 39 days fighting the Currowan fire but also fought blazes in Glenn Innes and Grafton as well a taking part in many of the between 150 and 200 jobs the Tomerong brigade does per year.

"RFS is a big part of my like," said the proud volunteer who has been a volunteer with the organisation for 11 years.

"I've never experienced anything like this year, combined with the drought it hit everyone.

"I just hope we'll get some regeneration now, of plant growth and animals."

He praised his employers John, Fay and John Lamont Snr, at Nowchem, saying they are really supportive of his involvement in the RFS.

"The whole business is like that, it is very community focussed and quite often takes the time to help our community," he said.

"The business likes to give back.

"And the support all brigades in the Shoalhaven has received from the local community has been incredible.

"I think that's the thing that has stood out the most for me.

"There has been so much community support for every brigade in the Shoalhaven - the fundraising, the cheering, even wanting to shake our hands - that makes all the hours of work worthwhile.

"It's the community that keeps us all going.

"While the community would like to thank us, we'd like to thank the community."

Amanda Saxton described the event as "spine tingling".

"It was just amazing," she said. "That's all I'm saying to people. No other words can really describe it.

"A real once in a lifetime experience.

"Meeting Brian May was a real fan girl moment.

"They were all so amazing with us.

"The crowd was mind blowing. Don't think I have ever seen or will ever see that many people."

Fellow volunteer and Callala Bay deputy captain Brett Thomas said being on stage in front of 75,000 was a blur.

"We watched the concert for most of the day before we went backstage, got dressed in our RFS uniform, were briefed on what we should do then it was showtime," Mr Thomas said.

"We went on stage for the finale, You're the Voice. We were also joined by representatives of the Canadian, US and New Zealand firefighting services.

"We stood in a line, waved at the crowd and 75,000 people cheered really loudly for us. Then a confetti cannon went off. It was an amazing experience."

Mr Thomas said he could only see a large blur of people.

"To be out there for the iconic song, at such a big event was a very humbling experience," he said.

Mr Thomas said the line-up of performers was "spectacular" with artists spanning generations so everyone could enjoy the songs.

"Everyone was singing along to all the acts. When Daryl Braithwaite sung Horses, the place went off," he said.

He said the concert was a chance to relax and enjoy himself after long and hard months battling fires across the state.

Sussex Inlet's Leroy Lidbetter said being on-stage during the finale was "absolutely exhilarating".

"Standing in front of 75,000 people all screaming and waving at you sent goosebumps through your body and it was a real privilege to represent the Rural Fire Service," he said.

"There were acts for everyone and the vibes through the audience was just thrilling and was great to see just how many people traveled far and wide to support communities and people affected by this crisis."

While being on-stage was exciting, backstage was just as thrilling.

"Stars like Celeste Barber, Olivia Newton-John, Brian May, KD Lang and John Farnham all wanted their pictures taken with us which was a little strange and the praise and thanks we got from production staff and everyone behind the stage was moving," he said.

"There were standing ovations backstage after our performance with crews lining the hallway and applauding us.
