www.bbc.com Scores of fires are burning out of control across Australia amid a heatwave that has seen temperatures exceed 40C (104F) in every state.
The most dangerous fires on Monday were in the state of Victoria.
About 30,000 residents and tourists were urged to flee East Gippsland – a popular holiday region – but evacuations were later deemed too risky as fires encroached on major roads.
A volunteer firefighter died battling a blaze in the state of New South Wales.

In total, 10 people have died in the nation’s bushfire crisis since September.
Meteorologists say a climate system in the Indian Ocean, known as the dipole, is the main driver behind the extreme heat in Australia.
What happened to the firefighter?
Authorities said the volunteer firefighter was killed and two others suffered burns after their truck rolled over in extreme winds while they were battling a blaze east of the city of Albury.
New South Wales (NSW) Premier Gladys Berejiklian described the death as “heartbreaking”.
“Words fail at times like this,” she wrote on Twitter.
Australian Prime Minister Scott Morrison said another firefighter was injured in a separate vehicle.
“This is awful news for the families and our sympathies are with them. These are testing times. We are so grateful for the courage and dedication of our firefighters,” he tweeted.
The volunteer firefighter is the third to be killed so far this fire season. Two volunteer firefighters, both fathers to young children, died on 19 December battling a blaze near Sydney.
Prime Minister Morrison was widely criticised for being abroad on holiday at the time, and returned home early.
How bad are the blazes in Victoria?
Scorching temperatures, strong winds and thunderstorms created dangerous conditions in Victoria on Monday.
In East Gippsland, three fires burning near the towns of Bruthen, Buchan and Bonang rapidly expanded as temperatures soared to the mid-40Cs.
Officials said the wind-driven blazes were “racing” towards the coast, and had moved faster than predicted.
