Dramatic footage shows firefighters surrounded by flames

A Fire and Rescue NSW crew have released footage of the terrifying moment their truck was overrun by flames.

The firefighters, from the Central Coast's Station 509 in Wyoming, were circled by a wall of fire south of Nowra and were trapped inside their vehicle as the fire front passed.

The minute-long clip shows the firetruck encircled by flames within mere seconds as it drives past blowing embers.

The confronting video, which was posted on Twitter last night, has since gone viral, attracting thousands of shares and comments.

Please get this some attention. 13 people dead and many more uncountable. And half a billion animals dead. It’s only now starting to get recognition. My country is on fire and we’re not getting the recognition it deserves. Disgraceful #AustralianFires pic.twitter.com/1bGeJwKFay
