The crew from Lambton forced entry to the unit and reunited the mother and child.

A car mounted a kerb, travelled through a front yard and crashed into a house at Charlestown on Wednesday. The car displaced a post supporting the roof on the home's verandah and smashed a sliding door.

Fortunately no one was home at the time and the female driver, though badly shaken, was not hurt.

Charlestown station officer Ben Lewis, who assessed the scene, said: "I was concerned that if we removed the vehicle immediately the roof would collapse."

"I called for our technical rescue vehicle, and we shored up the roof with Acro props before moving the car."

Amazingly, the car was able to be driven away. The owners of the house were due to return from holidays the same afternoon.

Fire crews responded to several car fires during the week. Wangi Wangi firefighters extinguished a car on fire in a driveway, containing the fire before it could spread to a nearby house.

A Fire and Rescue NSW off-road tanker from Cardiff was called to Wallsend to gain access to a car alight on a bush track.

Horse riders who had spotted the car fire directed the tanker to the fire.
