A volunteer firefighter has been killed after being struck by a falling tree in northern NSW.
The man was killed while battling the Hudson Fire near Walgett on Thursday afternoon.
Rural Fire Service members offered the man first aid until paramedics arrived.
He was transported to a Lightning Ridge medical facility before he died.
RFS Commissioner Rob Rogers described the man as a dedicated volunteer who died trying to help protect his local community.
"This gentleman made the ultimate sacrifice," Mr Rogers said.
"His tragic and untimely death is a solemn reminder about the dangers faced by our firefighters.
"Our thoughts are with his family, friends and firefighting colleagues at this terrible time. We are offering every assistance to his family and fellow brigade members."
The fire is at watch and act level and has burnt through more than 21,000 hectares.
Properties in the Glengarry area are being assessed for damage, with warnings dangerous weather conditions could exacerbate the fire.
