Fire has engulfed a home at Mannering Park this morning.

NSW Fire & Rescue and RFS crews were called to the single story fibro home on Barclay Avenue just after 3.00am to find the house well alight.

Newcastle Fire Command says all occupants have been accounted for.

Firefighters have been hampered by the presence of asbestos, while part of the roof has collapsed.

The cause of the fire is not known at this stage, but it’s not thought to be suspicious.
