Portugal Colonial - Australia declares state of disaster as bushfires rage

Temperatures soared past 40C as a heatwave blanketed the state of Victoria this week, with hot winds fanning some of the most dangerous fire weather seen since the Black Summer bushfires of 2019-2020.

One of the most destructive bushfires ripped through almost 150,000 hectares (370,000 acres) near Longwood, a region cloaked in native forests.

Fire crews have started tallying the damage, with early reports of at least 20 houses destroyed in the small town of Ruffy, about two hours' drive north of state capital Melbourne.

State premier Jacinta Allan on Saturday declared a state of disaster, giving fire crews emergency powers to force evacuations.

"It's all about one thing: protecting Victorian lives," she said.

"And it sends one clear message: if you have been told to leave, go."

Three people, including a child, were missing inside one of the state's most dangerous fire grounds.

"I appreciate there is a lot of concern," Allan said.

Although conditions had eased on Saturday morning, more than 30 separate bushfires were still burning.

The worst fires have largely been confined to sparsely populated rural areas where towns might number a few hundred people.

Photos taken this week showed the night sky glowing orange as the fire near Longwood ripped through bushland.

- 'Terrifying' -

"There were embers falling everywhere. It was terrifying," cattle farmer Scott Purcell told ABC.

Another bushfire near the small town of Walwa crackled with lightning as it radiated enough heat to form a localised thunderstorm, fire authorities said.

Hundreds of firefighters from across Australia have been called in to help.

Millions have sweltered through this week's intense heatwave.

Hundreds of baby bats died earlier this week as stifling temperatures settled over the state of South Australia, a local wildlife group said.

The "Black Summer" bushfires raged across Australia's eastern seaboard from late 2019 to early 2020, razing millions of hectares, destroying thousands of homes and blanketing cities in noxious smoke.

Australia's climate has warmed by an average of 1.51C since 1910, researchers have found, fuelling increasingly frequent extreme weather patterns over both land and sea.

Australia remains one of the world's largest producers and exporters of gas and coal, two key fossil fuels blamed for global heating.
