NSW traffic: M1 Pacific Motorway closed as bushfire burns south of Bulahdelah towards Nerong

The M1 Pacific Highway has been shut in both directions as firefighters battle a grass and bushfire burning south of Bulahdelah on the NSW Mid North Coast.

The blaze is burning on both sides of the M1 about 5km south of Bulahdelah and northwest of Nerong. Pushed by strong northwesterly winds, the fire is moving southeast towards the small community of Nerong.

The dangerous blaze comes as large parts of NSW swelter through heatwave conditions, with extreme temperatures and gusty winds heightening the fire risk across the state. Authorities have warned that the hot, dry weather could see conditions deteriorate quickly on the fireground.

NSW Rural Fire Service has issued a Watch and Act alert, urging residents in Nerong to prepare to leave now and those along Myall Creek and Myall River roads to monitor conditions and follow their bush fire survival plans.

Those without a plan are being told their safest option is to leave early.

Fire crews are working to contain the 462ha blaze, which remains controlled but continues to threaten nearby properties. The RFS has warned conditions could change quickly.

“Due to an increase in fire activity, the M1 Pacific Highway has been closed in both directions between Nabiac and 12 Mile Creek,” the NSW RFS said.

“If you are in Nerong, check and follow your Bush Fire Survival Plan.

“If you do not have a plan, decide what you will do if the situation changes. Leaving early is your safest option.”

“Fire may impact on your property. Make your final preparations now,” the RFS warned.

“Fill buckets, sinks and bath tubs with water ready to put out spot fires. Remove items which can burn from around your home, such as furniture and door mats.”

Those near Myall Creek Road and Myall River Road are being urged to monitor conditions.

Authorities closed the highway between Nabiac and 12 Mile Creek due to an increase in fire activity, with motorists told to avoid the area and check Live Traffic NSW for updates and diversions.

Locals are being urged to make final preparations, including filling gutters and water containers, moving flammable materials away from homes, and wearing protective clothing if they plan to stay and defend.

Smoke from the fire may cause poor air quality in nearby areas. The RFS has advised residents with respiratory conditions to follow their health plans and stay indoors if possible.

The next update from the RFS is expected by 1.30pm, or sooner if conditions deteriorate.
