Fire and Rescue crews extinguished a fire at an abandoned house in Bowral on Wednesday afternoon.
Crews were called to the Bendooley Street premises at about 4.30pm when smoke was spotted coming from the building.
Two Bowral crews entered the site, extinguished the fire and rendered the area safe.
Both crews from Bowral and Mittagong attended the scene for about an hour and a half.
Fire and Rescue will allege the fire was possibly started by vandals.
