Firefighters from Fire and Rescue NSW were arrived at the scene of the grass fire on the residential block on the corner of Jilba Street and Nunkeri Place at 4.03pm and extinguished the fire at 4.15pm.

According to police, the owner of the block was constructing a fence and a spark from an angle grinder ignited the dry grass.

Police are reminding people not to use tools that could cause a spark during fire danger periods and if using them not do it alone and have a fire extinguisher or water close by so if a spark does ignite it can be contained.
