Perth's eastern suburbs have been issued a bushfire emergency warning as six homes face the threat of serious damage from a nearby blaze.
The suburbs came under threat as another big blaze burned in the Margaret River region southwest of Perth.
People living in the eastern part of Martin, in the city's east, have been warned there is a threat to lives and homes, and they must act immediately.
The Fire and Emergency Services Authority (FESA) says if people have not left yet, and the way is clear, they should leave immediately for a safer place and take a survival kit.
If the home is not prepared, it is too late and the safest option is to leave, FESA says.
For those who are completely prepared and plan to use their home as a shelter, FESA says people should start patrolling their property to put out spot fires.
Residents have also been warned to close doors and windows, and turn off evaporative air conditioners, but to keep water running through the system if possible.
Anyone who is away from home should not try to return as the road conditions in the area could be very dangerous, FESA says.
HOMES DESTROYED
Earlier about 400 firefighters are battling to contain a blaze in Western Australia's Margaret River region after at least 19 homes were burnt.
Hundreds of residents and holidaymakers have had to evacuate the area after a prescribed burn got out of control.
Department of Environment and Conservation (DEC) Incident Controller Roger Armstrong said Thursday's priorities were containment of the fire, which was 80 per cent controlled with only a section north of the Margaret River still out of control.
