House and shed destroyed by Vic bushfire A LARGE bushfire in Victoria's west has destroyed at least one home and a shed, local residents say. The CFA has warned the fast-moving grassfire at Dereel, west of Melbourne, could raze more property. People who fled their homes ahead of the fire have told of the destruction but fire authorities have been unable to confirm the extent of the damage. "We have had unconfirmed reports of a house and shed lost at Dereel but because we are still fighting the fire we haven't been able to get in and make our own assessment," a State Control Centre spokeswoman told AAP. Three firefighters battling the blaze suffered smoke inhalation and burns, and were taken to the Ballarat Base Hospital in a stable condition. The CFA issued emergency warnings because of the fire, which has burned more than 1230 hectares. It's feared that a wind change on Wednesday night could send the blaze towards the community of Mount Mercer, and an emergency warning is in place for Dereel. An emergency warning has also been issued for a separate bushfire at Hallston, east of Melbourne. The CFA said the fast-moving, out-of-control fire would threaten the communities of Hallston, Dickies Hill Junction, Allambee South and Berrys Creek before 8pm (AEDT). The fire is burning across 312 hectares and creating spot fires a kilometre ahead of the front, the CFA said. Earlier on Wednesday, crews at Officer battled a fire which was looming near a major electricity connection between the city and power generators in the Latrobe Valley. Australian Energy Market Operator spokesman Joe Adamo said the fire did not pose a threat to Melbourne's electricity supply.
