Australia Bushfires: This is the moment a bushfire engulfed a house on Kangaroo Island while people are inside fighting to save the home. ONE TIME USE VIDEO.

A South Australian man, with a video camera in hand, has shown just how terrifying it can be trying to defend your home against raging bushfires.

On January 3, when an out-of-control bushfire tore across the picturesque Kangaroo Island, Peter Davis and his two sons Ben and Brenton stayed to try to defend Ben’s farm and home.

Peter, who has been a member of South Australia’s Country Fire Service for nearly 50 years, later said nothing compared to the firestorm that ripped through the farm.

The property is on the western side of Kangaroo Island in the suburb of Gosse. Most of the western side was evacuated earlier this month as fires tore through the bush. A father and son were also killed in the horrific fire.

In the four-minute long video, appropriately riddled with swear words, the three Davis men watch in horror as embers and flames fly past the house.

“My ute’s gone,” one of the men can be heard saying.

“Burn and p*ss off will you,” they later say.

When one of them suggests they need to go to the bathroom, Peter can be heard yelling at them not to.

“You don’t go into a room you can’t get out of,” he says.

“You go down the back...stay away from the glass mate.”

The men can also be heard joking throughout the video.

“That bloody couch is not going too good for me,” Ben says.

“You’re gonna need a new cubby house Ben,” Brenton comments.

In the footage a swing set in the background shimmers in the heat as fire engulfs it and whips across the yard.

The trio endured the firestorm for around four minutes before the front moved past the home.

Despite the three hoping to at least save the house from the fire’s ferocity, it was unable to be saved and caught alight.

In footage taken after the firefront had moved through, the true damage of the blaze was revealed.

“Yeah well we tried,” one of the men says.

“We saved two utes, unfortunately the house is on fire...I think we can, um, can that experiment there.”

A large trampoline sat overturned, with only the metal remaining, and cars and trucks sat destroyed and still alight.

“Unfortunately, we were unsuccessful and lost everything including the house, farm, over 400 sheep, over 400 beehives and Brenton’s ute. We got out at the end in two utes that sustained heavy fire damage,” Peter said.

In a post on Facebook later, Brenton, who runs Kangaroo Island Outdoor Action, described it as “a little more action than we like”.

“Really looking forward to these fires being over so that we can get back to turning your holidays into an awesome adventure,” he said.

The video has gone viral on social media with many praising the Davis men for showing the reality behind trying to save homes.

“Thank you for showing this, first the ember showers, then ember blizzard, then the wind, and the firestorm and what you can’t see there’s very little oxygen to breathe,” Chrys Benson wrote.

“So many belongings outside that could have made this catastrophic, the vehicles parked outside (note the ute very close to the house but in the leeside of the fire – very sensible), the gas bottles outside, and lots of outdoor furniture, bins and toys. Some can become explosive or some can get swept up in the fire storm winds, be burning and then smash into the house. This is why you should never stay. You can rebuild your home, but the loss of loved ones always stays with you. I am so glad you are all safe.”

Another commenter Mark Keynes also thanked the men.

“Sorry you lost stock, house and vehicles and thank you for taking the video,” he wrote.

“I hope other people who haven’t been through a fire see this before they decide to stay and defend their homes with a garden hose while wearing shorts, singlet and thongs.”

Eventually, the men made it away from the western side of the island after a terrifying drive through smoke haze and past smouldering trees.

“Yippee we made it,” one comments.

“Thank f**k for that,” another says.
