AN explosion heard across Two Rocks and Yanchep on Saturday night was a controlled burn-off, authorities say.
A Department of Fire and Emergency Services spokeswoman said a call about the “large explosion” near Cinnamon Meander in Two Rocks came through about 8.28pm on September 30.
She said two crews from Yanchep Volunteer Fire and Rescue and one from Two Rocks Volunteer Bush Fire Brigade attended.
“It was a controlled burn-off; the resident had a permit,” she said.
Yanchep Sergeant Chris Wride said police were also called but fire crews had put out the fire and there were no reports of injuries or damage.
Sgt Wride said the explosion may have been caused by someone throwing an accelerant onto the fire.
The bushfire season officially started on Sunday, October 1, with the State Government urging people to act now to be prepared through the ‘Are You Bushfire Ready?’ campaign.
