Hundreds of firefighters are still working to contain two bushfires in Western Australia amid hot and windy conditions.
Crews battled through the night as a blaze continued to threaten the semirural suburb of Martin, near Gosnells and the Korung National Park.
Authorities are bracing for gusts up to 80km/h, which could cause embers to jump containment lines, although conditions are expected to ease later on Wednesday.
An emergency warning has been downgraded to "watch and act" but about 150 firefighters remain on the scene.
Department of Fire and Emergency Services incident controller Aaron Hamill said most residents had opted to stay in their properties and had generally been well prepared.
But falling trees remain a serious concern, less than two weeks after a South Australian firefighter was killed and another seriously injured when a tree collapsed on their fire truck.
"It's actually riskier now as the crews move through the forest trying to black out and those trees are compromised," Mr Hamill said.
Two firefighters sustained minor injuries on Tuesday in a "burnover" incident when their vehicle was caught in the flames.
One firefighter sought medical assistance but was cleared, while the vehicle only sustained minor damage.
A watch and act warning remains in place for people on rural properties west of Mullalyup State Forest near Kirup, about 220km south of Perth.
About 100 firefighters are battling the blaze which is moving slowly in a southwesterly direction and has burned through 450 hectares.
"The alert level for this fire has been downgraded as the fire is now contained but not controlled," the department said.
"There is a possible threat to lives and homes as a fire is approaching in the area and conditions are changing."
