Fire and Rescue NSW is investigating the cause of Tuesday's building blaze in Walgett's main street. 

It happened about 6.30pm on 10 December at a building occupied by the Dharriwaa Elders Group on Fox Street, also the Castlereagh Highway.

A spokesperson for Walgett Shire Council said staff were assisting with the BBQ at the Walgett Singers Carols event in Gray Park when a plume of black smoke was spotted nearby.  

Staff quickly moved to investigate and found the Galuma-li building on Fox Street ablaze, with flames breaking through the windows and the structure rapidly consumed by fire. 

Council's spokesperson said the building had already sustained extensive fire damage.  

Council General Manager Andrew Brown, drawing on his experience as a former Inspector at the Rural Fire Service, provided support on site and remained with emergency crews until the fire no longer posed a risk to nearby properties. 

Mayor Jasen Ramien was also on site, attending with the Collarenebri Rural Fire Service crew and assisting throughout the response.  

Council also acknowledged the swift action of its roads team, who quickly blocked surrounding roads to ensure public safety during the incident. 

A coordinated response from local emergency services ensured the fire was contained as quickly as conditions allowed.  

Their efforts, supported by essential service workers, helped prevent damage to surrounding sites, including the Old Council Chambers, which has been used as a museum.  

The neighbouring vet clinic has told the Western Plains App said animals were ok and safe.

''There was smoke inhalation and minor damage but animals and workers are okay."

Council Mayor Jasen Ramien has thanked community, council workers and emergency service personnel.

 ''Their combined efforts were instrumental in protecting nearby buildings and safeguarding the historically significant items at the museum," he said.

The loss of Galuma-li will be deeply felt across the Walgett Shire as the building served as a vital hub for service, culture, and connection.  

Mayor Jasen Ramien said, "It is very unfortunate for the Dharriwaa Elders Group and the entire community.  

"The Galuma-li building was a new space and a setback to all they have been working to achieve.  

"With the support of Council and the wider community, we hope they are still able to continue offering their important programs and services while planning the next steps." 

Council expresses its sympathies to the Dharriwaa Elders Group and all those who contributed to the project and its vision.  

Council's leadership team has reached out to offer the use of Council facilities, recognising the important role their activities play in supporting the community.  

Council is also encouraging local groups with available spaces to come forward and provide support where they can. 

The Castlereagh Highway was closed in both directions between Wee Waa Street and Euroka Street while firefighters battled the blaze.  

With police assistance motorists were diverted via Bate St, Vanstone St, Peel St, Montkeila St to return to Castlereagh Hwy.
