Smoke warning for locals after bushfire at Herdsman Lake impacting Glendalough, Osborne Park and Wembley

Advice for the public to avoid Herdsman Lake remains in place following a blaze that ripped through the regional park in Perth’s north on Monday.

Department of Fire and Emergency Services warned on Tuesday morning that there was still “a lot of smoke” in the area, including Selby Street North, Walters Drive, Herdsman Parade and Moondine Drive in Glendalough, Osborne Park and Wembley.

The public is advised to stay alert and monitor surroundings, and to avoid walking trails in the warning area.

The lake itself acted to contain the flames that burned across the centre island of the lake on Monday while firefighters did their best to bring the situation under control.

More than 19.5ha was burnt before an afternoon wind change turned the fire back on itself, making the task easier for fire crews.

At its peak, ash from the fire was carried on the wind and spread throughout the nearby Osborne Park business district, leading to fears and an alert about the risk of falling embers.

It’s unknown what caused the blaze but DFES says the circumstances appear suspicious.
