Cessnock City Council has called off tonight's Carols in the Park because of the bushfire threat and amount of smoke in the area.
The council's general manager Lotta Jackson said it was a difficult decision to cancel the event at short notice but the community's health and safety had to be put first.
"Due to the size and location of these fires a blanket of smoke has settled across Cessnock and ash is falling from the nearby blazes," Ms Jackson said.
"The advice from the Department of Planning, Industry and Environment is for residents to stay inside as much as possible, particularly the elderly, those with lung or heart issues and young children. In light of this we have unfortunately had to make the call to cancel this special community event.
"As a council we have a responsibility to keep our community as safe as possible and reduce potential negative health impacts. "
It comes after the council initially announced on Wednesday it had cancelled the fireworks component of the event.
Following the disappointment of the cancellation of the fireworks display at tonight's Christmas on John Street, sponsors Yancoal in conjunction with Singleton Council will donate the value of the fireworks to the local NSWRFS.
