A devastating bushfire in Perth could have destroyed more than 20 houses, according to estimates from fleeing residents.
Despite the efforts of dozens of firefighters and helitac helicopters in atrocious conditions, properties near Parkerville and Stoneville were razed by the fast-moving fire.
More than 100 firefighters and 50 vehicles remained on the scene late on Sunday, and waterbombers were deployed to battle the blaze.
Burning embers were being blown around homes, and spot fires were starting up to 150 metres ahead of the fire, the Department of Fire and Emergency Services said.
At least two firefighters have been treated for heat exhaustion.
Just before noon on Sunday, residents in the eastern part of Mundaring were told to leave their homes immediately. Less than 30 minutes later, locals were told it was too late to leave, as it could be deadly if they did.
By 4pm, more than 250 hectares had been burnt.
