Casuarina bushfire: Bushfire downgraded to advice level as authorities confirm no threat to lives or homes

A bushfire in Perth’s south has been downgraded, with authorities confirming there is no longer a threat to lives or homes.

The Department of Fire and Emergency Services issued an emergency warning for residents in parts of Casuarina about 3.45pm on Monday, before downgrading it to an advice level about 6.30pm.

The blaze — first reported about 3pm — is contained and controlled, and has razed at least five hectares of land.

Locals have been urged to stay alert and continue monitoring their surroundings.

“Watch for signs of a bushfire, especially smoke and flames,” a DFES spokesperson said.

“Be aware of other potential dangers such as falling trees and damaged properties and infrastructure.

“Close all doors and windows and stay inside if smoke is causing you concern.”

Firefighters were at the scene fighting the blaze on Monday afternoon, with several water-bombers assisting ground crews from the sky.

Shocking footage released by Main Roads WA during the peak of the bushfire showed thick dark smoke blowing across Tonkin Highway.

Temperatures near Jandakot soared to 41.3C about 2.30pm on Monday afternoon, before dipping to just 36.7C an hour later.
