A 56-year-old-woman from Hamley and a 69-year-old man from Pinery have been confirmed dead.

At least 13 people have been hospitalised, five in critical condition and at least 16 houses destroyed.

The fire has burned through around 90,000 hectares.

The fire has affected an area that is bounded approximately by Roseworthy, Kapunda, Mallala, Owen and Riverton.

Within 20 seconds everything was gone, Hamley Bridge resident Paul Vogue who lost his house in yesterday’s fires, told ABC. “It just came over and it just absolutely took everything out, just the whole lot,” Mr Vogue said.  

“Two houses here, the barn, cars, everything it just took it straight out, all in a matter of 20 seconds.

“It was just a horrendous fireball that you just wouldn’t know what it was until you saw it because it was devastating.”

Mr. Vogue said he lost some birds but managed to save other animals.

“We saved all the horses, our dog, my partner and me. We’re thankful we’re alive,” he said.

Brenton Eden from the CFS said the situation today is very different from yesterday.

“Conditions are very cool, probably around 19 degrees now compared to what we had yesterday,” he said.

“The wind has dropped out, the relative humidity is high so we’ve had a very comprehensive night shift where they have blacked out the perimeter of the fire, they’ll continue to do that today and tonight and into the coming days.

“As you can understand, 211km of the perimeter to black out is an enormous task, but we’ve really got a multipronged approach today. We need to deal with identifying the structures that have been lost and to ensure we haven’t lost lives in those structures that have collapsed.

“We need to get the roads opened and that will require chainsaw operators to remove trees and fallen timber. The issues of animal health and destruction and disposal will be an issue we need to coordinate with today, as well as the other essential services so we can get the roads open to get power back into the community.”

Mayor of Gawler, Karen Redman, said the fire was a “big, devastating event”.

“You’re talking about farms, crops, hays that’s been stored in sheds. When you think about the land mass, [it’s massive]. One minute you’ve got to farm your land to get your crop in and then next minute it’s not there,” she said.

“Certainly, businesses have put their hand up to help. Council is providing that practical support…I got a call from Nick Champion (our federal member for Wakefield) who is happy to advocate for people later down the track when they need help.

“Everybody wants to help and I’m sure the Federal Government will come to the party, but that may be further down the track.

“Again people band together and just want to help. What I see is just a wonderful outpouring of support, empathy.”
