The emergency warning covers parts of Boya, Darlington, Greenmount, Helena Valley and Hovea in the Shire of Mundaring, with the perimeter defined by major roads and streets including Great Eastern Highway, Coulston Road, Approach Road, Clayton Road, Victor Road, Beenong Road and Darlington Road.

The affected region encompasses these same communities within Mundaring, and residents should follow official updates for precise boundaries.

Emergency alerts urged evacuation along the Great Eastern Highway in either a westerly or easterly direction, and to leave now for a safer place if possible.

A bushfire emergency near Mundaring, about 35 kilometers east of Perth, has led to an evacuation order for nearby residents, who must evacuate immediately as the fire remains out of control and uncontained.

The fire is moving in a north-easterly direction, threatening lives and homes, so residents in affected areas should leave now rather than wait to see what happens.

Once evacuation has begun, it is too dangerous to return home, and residents should not attempt to delay or return if not already at home.

A designated evacuation shelter is available at Brown Park Community Centre to accommodate those displaced by the fire.

Official updates indicate the fire was reported just before 5:00 p.m., remaining out of control and uncontained about an hour later.

Residents should monitor official channels for warnings and incident maps on the EmergencyWA website.

An evacuation centre has been opened at Brown Park Community Centre in Salisbury Road, Swan View, with attendees advised to bring essential items like medications and identification.

For ongoing local updates, residents can use ABC Emergency and the ABC Listen app for radio updates.

If evacuation is not possible, residents should shelter in place but be prepared to take cover inside homes, as extreme heat can be deadly before flames reach the interior.
