Residents in Perth's southwest have been warned it's "too late to leave" as a rubbish tip fire burns out of control in Kwinana.
An emergency warning has been issued for The Spectacles, Orelia, Medina, Naval Base, Postans, Kwinana Beach and Hope Valley in the Kwinana local government area.
Three structures had been damaged so far and 150 people evacuated from an aged-care facility, the ABC reported.
Western Australia's Department of Fire and Emergency Services said the fire started near the intersection of Thomas Road and Gilmore Avenue in Orelia, and "hazardous fumes" in the air from a rubbish tip fire made it too dangerous to leave.
The DFES said it was too late to leave for people bounded by Beard Street to the north, Rockingham Road to the east, Thomas Rd to the south and the coast.
"Leaving now would be deadly, hazardous fumes are in the air from a rubbish tip fire," the DFES said.
"You must shelter in place for safety.
"People in the area should remain inside, out of the smoke or fumes, with doors and windows closed. Air conditioners should also be switched off."
Others in the emergency warning area have been told to leave for a safer place if the way to leave is clear.
"If you cannot leave, you need to get ready to shelter in your home," the DFES said.
"Go to a room in your home away from the fire front and make sure you can easily escape. Choose a room with two exits and water such as a kitchen or laundry.
"If you are not at home, it's too dangerous to return."
Those self-isolating or quarantining due to Covid-19 have also been told to leave if it is safe to do so.
They have been advised to find alternative accommodation with family or friends who live away from the area.
"If you are unable to return to your quarantine location within one hour, telephone WA Police on 131 444 to advise them you have had to leave due to an emergency," the DFES said.
"Regardless of your location, continue to follow Covid-19 precautions and maintain appropriate physical distancing."
A watch-and-act message has also been issued for parts of Parmelia, The Spectacles, Calista, Orelia, Leda, Medina, Kwinana town centre, Postans, Kwinana Beach and East Rockingham due to the fire.
Those not prepared and who plan to leave have been told to leave if the way is clear.
Those south of Thomas Rd have been advised to leave in a southerly direction, while those north of Anketell Road should leave in a northerly direction.
It comes after the Wundowie bushfire north of Perth was downgraded to advice level after it was brought under control on Sunday evening.
The fire burnt through 65 hectares after it started on Saturday afternoon.
The DFES said the Great Eastern Highway had reopened to all traffic, but speed restrictions remained in place.
About 20 firefighters remain in the area patrolling and mopping up hotspots.
