INVESTIGATIONS are continuing into a 44-hectare blaze that threatened homes at Collina earlier this month.
Police and fire investigators are working together to determine the cause of the fire, which ignited at the intersection of Rifle Range Road and Annies Lane on Wednesday, November 6.
About 1.30pm, fire authorities responded to the Scenic Hill fire, which was burning rapidly towards homes at Collina.
Winds coming in from the north combined with the unseasonably dry undergrowth and 31 degree temperature had fire fighters rushing to control the flames.
While the nine Rural Fire Service (RFS) crews, supported by Fire and Rescue NSW and a water bomber aircraft, managed to contain the fire by the afternoon, timber throughout the fire ground continued to smoulder for several days.
Police have interviewed a number of suspects but have not made any arrests as yet.
"Any fire is suspicious until proven otherwise," Griffith Police Inspector Tony Reneker said.
"Fires don't just start by themselves."
Meanwhile, RFS zone manager Kevin Adams has called for volunteers to assist with the Griffith Control Centre's social media management during emergencies.
Superintendant Adams requires Facebook and Twitter experts to help update the RFS pages during local emergencies, using RFS intel to keep residents informed.
"We need people who are able to come in and get on Facebook and Twitter and provide updates on a continual basis during major incidents," Superintendent Adams said.
Volunteers must be proficient in using social media.
Anyone interested in volunteering can visit the control centre on Wakaden Street and speak to Lexi King, or call the RFS on 6966 7800.
