At least 71 homes have been destroyed in a bushfire raging out of control near Australia's fourth-biggest city Perth, authorities said Wednesday, as they told residents to ignore a virus lockdown and evacuate threatened areas.
The blaze has torn through large swathes of land in the Perth Hills and was moving towards more densely populated areas.
Six firefighters received minor injuries -- including one who officials said suffered burns and continued working to extinguish the blaze -- but no deaths or serious injuries have been reported so far.
"To the people who have lost their homes, it's just devastating for them. Our thoughts go out to them," Western Australian fire commissioner Darren Klemm said.
Several emergency warnings were issued with conditions set to worsen later Wednesday and strong gusting winds expected to fan the flames.
The blaze hit a population that had just been forced into a snap lockdown after a security guard in Perth contracted the British strain of Covid-19, apparently from a returned traveller in hotel quarantine.
About two million people in and around Perth fell under the stay-at-home orders imposed on Sunday.
As the firefront edged nearer to more populated areas, Klemm called on locals to act swiftly to escape the potentially deadly blaze despite the coronavirus restrictions.
"What we don't want is indecision from people about whether they should evacuate or not when we require them to evacuate," he said.
"So that evacuation overrides any quarantining requirements that people may have."
- 'Like a bomb had gone off'
Hundreds of people have fled the area since the bushfire was sparked on Monday, with many sleeping in evacuation centres overnight.
Among them is Peter Lavis, 68, who evacuated two nights ago after watching distant smoke quickly transform the landscape until it "looked like a bomb had gone off".
"We ould see the fire clearly, the red glow and occasional rush of flames going up," he told AFP.
"We had a little family conference and decided the best thing to do was to leave."
Lavis said he believed his home was safe while a neighbour had reported his eldest daughter's nearby house was also standing despite everything around it being burned.
"It's some of the best news but also the saddest -- a lot of people haven't been so lucky," he said.
Bushfire smoke has blanketed Perth, about 30 kilometres west of the blaze which had a 75-kilometre (47-mile) perimeter Tuesday and has so far burned almost 10,000 hectares (24,700 acres).
"It was just scorched earth. Even where I was behind the fire there was a lot of active burning because the crews just had to react so fast," local mayor Kevin Bailey told public broadcaster ABC.
Temperatures were forecast to peak at 35 degrees Celsius (95 degrees Fahrenheit) on Wednesday before a predicted ex-tropical cyclone could bring rain and cooler temperatures but more unpredictable winds later this week.
Klemm cautioned there were "challenging times ahead, and that's once again the clear message to the community... there is still a long way to go with this fire".
More than 200 firefighters were battling the bushfire supported by water-bombing aircraft.
Emergency Management Minister David Littleproud praised them for their "tireless work" in recent days, saying "these men and women are putting their lives on the line" to protect others.
More than 3.5 million hectares were burned across Western Australia during the country's devastating 2019-2020 climate change-fuelled bushfires but the state was largely spared the loss of properties and lives seen in Australia's more densely populated southeast.
