Human remains have been found in two burned out houses in the town of Yarloop, south of Perth.

It’s believed they’re the bodies of two men in their 70s, who’ve been missing since fire swept through the town earlier this week.

Vital reinforcements are arriving to relieve exhausted firefighters in Western Australia.

A team of 60 are being flown in from New South Wales, to help deal with the fire which destroyed more than 100 homes at Yarloop, south of Perth.

Wayne Gregson of the state’s Emergency Services Agency, said some local firefighters have been going for two days straight.

“It’s just around fatigue management, there’s some very tired fire fighters out there in need of some relief and we want to maintain the capacity for Western Australia. So we’ve got a great arrangement with other states to bring resources in.”

State Premier Colin Barnett said the extra help is badly needed.

“Guys have been out there fighting the fire for 30 hours on end – exhaustion is coming in, we’re pleased that a new contingent of firefighters is coming from new South Wales, and I very much appreciate the support of New South Wales Government.”
