A second bushfire in 10 days is being treated as suspicious by authorities as firefighters north-east of Albany battle to get the blaze under control. Speaking from the Incident Management Team in Albany on Thursday afternoon, Department of Fire and Emergency Services Great Southern district officer Diarmuid Kinsella said the source of the fire is under investigation. “We are treating it as suspicious; that’s about all I can say at this stage,” Mr Kinsella said. The fast-moving and unpredictable blaze was first reported at 6.02am on Wednesday morning and has so far burnt about 5067ha in parts of Green Range, Kojaneerup South and Mettler in the City of Albany. Mr Kinsella said his main concern was the hundreds of homes which are now without power after the fire jumped South Coast Highway and damaged power lines. Western Power confirmed that 336 homes and businesses are currently without power and those in the bushfire zone will have to wait until Western Power can access the fire ground before their power is restored. About 100 firefighters are on the scene actively fighting the fire and strengthening containment lines, including volunteer and career firefighters, farmer response units, machinery contractors, and personnel from DFES and the Department of Biodiversity, Conservation and Attractions. A large air tanker was sent in to assist on Wednesday and four small water bombers were supporting on Thursday. Mr Kinsella said that given the steep, hilly terrain and challenging weather conditions, which caused “erratic fire behaviours”, crews had done a “fantastic job” in protecting lives and structures with no losses reported. “There’s probably five or six houses along South Coast Highway and a number of those have evacuated today,” he said. After going to emergency twice – one on Wednesday and again on Thursday – the fire was downgraded to watch and act at 7.38pm on Thursday night. “As we move into the evening, the weather’s more on our side and crews can contain things,” he said. The out-of-control blaze comes just 10 days after another serious bushfire in the City of Albany on the Vancouver Peninsula. Nearly 50 firefighters and two water bombers worked to contain the blaze, which started near the access to Whalers Cove Beach on Monday afternoon, January 29. A day later, Albany detectives said they were treating the fire as suspicious with detectives appealing for public information into how the blaze started.
