Melbourne - At least 20 homes have been razed in south-eastern Australia in the worst fire conditions seen since a deadly 2009 inferno which killed 173 people, with flames threatening the nation's second-largest city, officials said on Monday.

Hot, dry winds and soaring temperatures fanned scores of major blazes across the south-east on Sunday, with Victoria state sweltering through its worst fire risk weather in five years.

The emergency came exactly five years after the so-called Black Saturday firestorm devastated the state, flattening whole towns in what was Australia's deadliest natural disaster of the modern era.

Victoria state premier Dennis Napthine said Sunday had been the worst fire danger day since Black Saturday.

“There are about 20 homes that have been affected, the exact number will be determined as we get the opportunity for the police to get in and examine those issues directly,” he said.

“At this stage we have no evidence of loss of life, which is a great effort by the firefighters and all emergency services, and at this stage we have no evidence of serious injury. That's first and foremost our priority - protection of life.”

A major open-cut coal mine was ablaze, with a nearby power station in the path of one fire. Napthine said emergency crews were working “very, very hard in that area to protect those strategic assets”.

Four blazes remained at emergency level on Monday, including a 40km front on the outskirts of Melbourne, Australia's second city, with tens of thousands of hectares scorched.

One man told the Australian Broadcasting Corporation that fast-moving flames had cut off his evacuation route, forcing him to stay and defend his property near Forbes, north of Melbourne.

“Amazing how fast it come up the gully and how big the fire front was. It was a massive wall of fire,” said the man, who identified himself only as Peter.

“I really didn't think I was going to make it but luckily in our case the fire spread around our house and our shed, went either side of us. And then for a good five, 10 minutes I thought 'this is it’.”

Another Forbes woman said “it was like the whole world was alight” when flames rushed up a gorge towards her property.

Wildfires are common in Australia's December-February summer months. Infernos destroyed 25 homes in the south-east last month following a week-long heatwave that also saw 56 homes razed in separate blazes on the west coast.

Experts say heatwaves are becoming longer and more frequent in Australia due to climate change.
