A house fire in Perth's southern suburbs early this morning caused $400,000 damage.
Firefighters attended the blaze on King Road in Oldbury about 1.50am after a passerby alerted authorities.
The fire was quickly extinguished and no-one was inside at the time.
A police spokesman said the Department of Fire and Emergency Services were still trying to contact the property's owner.
A fire investigation officer will be at the house later today, but police believe the blaze was not suspicious.
