A photograph of three exhausted firefighters has been shared across social media, with people praising the men for their “selfless” act.

The worn-out firefighters were pictured covered in ash after battling bushfires in Tasmania. More than 191,000 hectares have been destroyed across the state.

The picture was shared to Facebook by The Wolfe Brothers and shows Jason Luck, John Kroczewski, and Paul Catteral.

“If you are unaware currently in Tasmania there is some seriously bad Bush Fires. Nearly 3 per cent of the state has been destroyed,” the post read.

“A friend sent us this photo. LOOK at these incredible men, they look like they have been in a war zone!”

The photo was taken by fellow firefighter John Lyons after they had been battling blazes for 12 hours at Gell River.

The picture was uploaded on Friday and has since had over 37,000 likes and nearly 24,000 shares.

Thousands of people flocked to the comment section to praise all of the firefighters currently fighting the fires across the state.

“These guys are the unsung heroes of this great country,” one person said

“Can’t thank these hero’s enough. They deserve so much more than just a thank you,” another wrote.

One added: “They are amazing selfless people.”

An emergency warning remains in place for central Tasmania as dozens of fires continue to burn across the state.

Volatile fire conditions caused blazes to flare across the state on Sunday and some towns remain under threat.

The emergency warning is in place for Reynolds Neck with residents warned burning embers would threaten homes before the main fire front and told to go to a safer location if the path was clear.

Waterloo, Surges Bay, Brooks Bay, Glendevie and Police Point in the south had emergency warnings in place overnight. They have since been downgraded to watch and act advice level.
