Fire bombers from South Australia have been enlisted to help battle a huge wildfire in the Northern Territory.

The blaze, which remains at an “advice” level alert, is contained but burning east of Tennant Creek in an area over 9300sq km under “high to extreme” weather conditions.

Three bombers are positioned in Tennant Creek, and two strike teams with tankers have been deployed from South Australia, NT Fire and Emergency Services said.

NT Police Commissioner Michael Murphy said all measures were being put in place to protect people and assets from the fire, which had an edge extending hundreds of kilometres.

“Our thoughts and thanks are with the pastoralists who are working incredibly long hours protecting their property and stock, and we thank all the hard working frontline personnel leading, surveying and putting in mitigation strategies to minimise the impact of this large and uncontrolled fire,” he said in a statement.

Approach with caution

The Barkly Highway has re-opened but motorists are still urged to delay travel in the area until conditions are clear.

A fire ban remains in place for Darwin and the Adelaide River, Gregory South-East and Barkly North areas.

A health alert has been issued for Tennant Creek and the surrounding areas impacted by smoke, while residents in the Barkly region are urged to make fire preparations.

The Bureau of Meteorology has advised wind conditions across the Barkly will ease on Wednesday.
