Western Australia's police minister has said police are "incredibly concerned" that some of the serious fires burning in the state may have been deliberately lit, and are further worried by a number of people flying drones near the blazes.
At least one home has been lost to a large fire burning in Geraldton, which authorities suspect was deliberately lit.
It has already burnt through 160 hectares and is expanding significantly after it was reignited this morning by strong winds, having started on Friday.

Firefighting crews have been brought up from Perth to assist, with four waterbombers, 55 vehicles and two Black Hawk helicopters currently battling the blaze, Police Minister Paul Papalia said.
He said there was an "incredibly confronting situation" this morning as 80km/h winds pushed the fire towards the Nazareth aged care facility, but it had been saved.
"An incredible effort went into stopping that fire," Papalia said, also praising the wider community's response to the emergency as "an example of what is best about the West Australian country community".
But the minister went on to slam the "appalling behaviour" of suspected arsonists behind the fire, saying detectives are already on the case.
There are no suspects as yet.
He said police were also very concerned that multiple people had been operating private drones in the vicinity of fire fields, impeding firefighting efforts and breaking the law.
