The video has received tens of thousands of likes and shares on Facebook Mr Hughes said the job has long hours but "there's nothing worse than working with no morale"

The 20-year-old volunteer firefighter of two years, Griffin Hughes, was backburning well into Sunday night when he and his crew took a well-deserved, 20-minute break.

"We were backburning as a fire was coming over a hill in Widden Valley, to try set it back on itself," he said.

The crew had been working since 3:00pm that day and finally got to have dinner about 10.30pm.

Mr Hughes said it was then that his crew, "blasted music over the [fire] truck" and filmed him boot-scooting to Blanco Brown's The Git Up.

"That's when I thought I'd get out and have a boogie and put a smile on their [the crew's] faces."

Brown's song has sparked an internet dance craze known as the 'Git Up Challenge' where people post their version of the singer's dances moves.

"Sometimes when it's late at night, during dinner break, you have to make a little bit of entertainment for each other," the Mangoola Rural Fire Brigade posted on Facebook along with the video.

Mr Hughes said these moments can help crews get through long hours of firefighting.

"There's nothing worse than working with no morale," he said.

"The job's hard. And it's long hours. But there's no reason we can't still try and have fun."

It's also been circulating on Twitter.

One Facebook user commented: "Great to see this during the tough times they have endured … after all it was in his meal break.

"If you can keep up the spirits of your fellow mates good on you. Loved that cheeky smile.

"Thank you to you and the other members of your crew and every single fireman for protecting and fighting for our beloved Australia."

Another wrote: "Good to see their spirits aren't broken. Thank you for the awesome job you are all doing."

The Mangoola Rural Fire Brigade's Facebook page also replied to a comment, saying Mr Hughes had received "hundreds" of friend requests after the video was posted.

On Tuesday in NSW, milder conditions were providing a short reprieve for exhausted firefighters across the state but dangerous bushfire weather is set to return on Friday.

In NSW alone, there have been 1,588 homes destroyed and a total of 653 homes damaged this fire season.

The figures are expected to rise as authorities continue to survey firegrounds.
