A “mega blaze” raging across a 60km (37 mile) front north-west of Sydney cannot currently be put out, Australian fire officials have warned.
The fire across almost 300,000 hectares (1,150 sq miles) is an hour’s drive from the nation’s most-populous city.
People who cannot defend their property from approaching fires have been told they should leave immediately.
Since October, bushfires have killed six people and destroyed more than 700 homes across Australia.
The severity of the blazes so early in the fire season has caused alarm, and prompted calls for greater action to tackle climate change.
At 12pm there are 95 bush fires, with half yet to be contained. There are currently 12 fires at Watch & Act level, and more than 2,200 firefighters out in the field. While fire activity has reduced this morning, there's still 8 areas of Total Fire Ban today. #nswrfs #nswfires pic.twitter.com/JYWiIoHaLe
