I should add the following commentary from the ABC Canberra.
This terrifying dashcam footage from the Currowan fire earlier this month has been shared by a South Coast fire brigade as a reminder of how quickly a bushfire can move.
The Dunmore Rural Fire Brigade was in the Shoalhaven region on January 4 when a firestorm blew through - luckily, they saw it coming and were able to protect themselves, many quickly fleeing the area.
The footage was filmed from the cabin of a fire vehicle that could not move or decided not to.
You can see they have activated the emergency "halo" which is a sprinkler system mounted on the roof of the vehicle to spray a protective ring of water around the vehicle if it is over run by a fire event. Not sure it would be much fun inside but they probably rolled down the fire blankets on the side windows as extra protection.
