An out-of-control bushfire is threatening homes and lives north of Perth, with residents told to act immediately to survive.

An emergency warning was issued early on Monday for Bindoon, Breera, Gingin, Lennard Brook, Mooliabeenee and Moondah, 60km north of the city.

“You are in danger and need to act immediately to survive,” WA’s Department of Fire and Emergency Services said.

“There is a threat to lives and homes.”

Crews are struggling to contain and control the fire, which is moving in multiple directions and has already burnt about 2600 hectares.

Almost 250 firefighters and support crew are battling the blaze, with aerial support expected to join the fight at first light on Monday.

Residents were told to leave immediately if the way was clear, with an evacuation centre opened at the Bendigo Centre Recreation Grounds on Weld Street in Gingin.

To the southwest of the region, a fire was burning at watch and act level near Bambun, Muchea, Pinjar, Yanchep and Yeal, with 2287 hectares burnt.

Homes and an RAAF base in Perth’s north were threatened on Saturday afternoon when fires broke containment lines amid intense heat.

The blaze broke out near the entrance to RAAF Base Gingin, a facility primarily used for pilot training.

It was one of four significant fires in the Wanneroo and Chittering areas, where temperatures cracked 41C just after 2pm.

The Bureau of Meteorology expected severe heatwave conditions to persist into the coming week across much of the state, including Perth and the rest of the southwest.
