Authorities in Australia have urged tens of thousands of people to move to safety amid concerns that bushfires will burn out of control this weekend.

BBC News reports temperatures are expected to soar above 40C in parts of south-east Australia today, with strong winds increasing the fire danger.

Officials said it is expected to be a "very dangerous day".

Since September, fires in Australia have killed at least 20 people, while dozens are missing.
