Firefighters were called to the stock route near Wrights Road, off the Lincoln Causeway, on Saturday afternoon.

Two separate fires broke out on the roadside, a short distance apart, about 7.20pm.

The fires were contained before they could spread, but about 50 square metres of grass and scrub was burnt out.

Police set up a crime scene and an arson chemist was called to the area.

Detectives are investigating the cause of the fire.

Three fire trucks had attended the scene.
