Out-Of-Control Bushfire Threatens Properties In NSW

An emergency warning has been issued to people in the vicinity of a fast-moving bushfire burning south of Inverell in northern NSW with authorities declaring some rural properties are being threatened.

Firefighters and aircraft have been unable to slow the fire which is burning to the east of Lake Copeton and spreading quickly.

Properties between Lake Copeton and Tingha are under threat, the NSW Rural Fire Service said on Tuesday afternoon.

"Emergency alert telephone warnings are being sent to homes and mobile phones in the area," the service said.

Those impacted by the fire are advised to seek shelter and protect themselves from its heat.

Residents who plan to stay with their property are being advised to make their final preparations.

The fire has already burnt more than 300 hectares, the RFS said in a statement.

Crews are battling some 40 bush and grass fires across the state with nine not yet contained.

A watch and act alert has also been issued for a bushfire at Warrabah near Tamworth with RFS warning fire activity is increasing in the area.

High temperatures and strong winds are fanning the out-of-control Linton fire with a number of rural properties under threat.

A statewide fire ban has been issued for Tuesday with temperatures tipped to reach the low-40s in some areas accompanied by high winds.
