Lives and homes in Mirranatwa under fire threat A FAST-moving bushfire is threatening a town in the Grampians National Park in Victoria's west. The Country Fire Authority says residents in the town of Mirranatwa have been told the 300ha fire is expected to impact their town by about 5.30pm. A water bombing helicopter was working to help more than 100 firefighters at the fire front bring the blaze under control. An emergency warning has been issued for the blaze which broke out on Thursday following lightning strikes. A CFA spokeswoman says crews are in the town working on asset protection. "We've issued an emergency warning, it (the fire) may impact the town," she said. She said there was no current information on winds forcing the fire in a south-easterly direction towards the town. It comes as hundreds of fires continue to burn around the state. Since Thursday more than 380 bush and grassfires have started, according to the CFA, with lightening the cause of most. Fire services commissioner Craig Lapsley said the hot, dry weather had made conditions worse. At least 22 New Zealand fire fighters and 40 from New South Wales are expected to arrive on Wednesday to boost support. with Christopher Gillett
