Central Coast firefighters have battled to contain another blaze, which has since been linked to squatters, in Gosford.
Two crews were called to Keevers Lane just after 11:30 this morning, after smoke was seen coming out of an abandoned building.
They managed to keep the damage to one room.
It follows a string of fires across the region, including an inferno in an abandoned building at The Entrance last week.
Vision only.
