Bushfire threatens homes in western Victorian Grampians A LARGE bushfire is threatening homes in the Grampians region of western Victoria. Eight houses in the small community of Mirranatwa, 30km north of Dunkeld, are expected to be affected by the blaze. The 800ha fire, which is burning out of control, jumped containment lines and entered farmland in the early hours of Monday morning after strong northerly winds caused spot fires up to 300m ahead of the fire front. Two hundred firefighters and 14 aircraft are battling the blaze in the southern portion of the Grampians National Park. The CFA is warning conditions remain unpredictable, with slightly elevated winds increasing the potential for the fire to join up with another large but currently controlled fire burning only a kilometre away. A spokesperson said warnings for residents in Mirranatwa could fluctuate between watch and act and emergency throughout the day, and those who didn't plan to stay and defend their homes should leave immediately. Large volumes of smoke are being generated, and a relief centre has been set up in the Senior Citizens Clubrooms in Lonsdale St, Hamilton. Two other significant Victorian fires continue to challenge firefighters, at Harrietville in the north east, and Dargo in Gippsland. Around 1000 firefighters, 240 vehicles and 60 aircraft are at work across the state, as temperatures reach the mid to high 30s. The blaze comes as a University of Newcastle report published on Monday found the psychological trauma of being the first responders to medical emergencies may be leading to suicide, alcohol abuse and depression among firefighters.
