A woman was seriously injured when a car and caravan rolled over on Indian Ocean Drive this afternoon.
The accident happened about 1.45pm about two kilometres south of Knobby Head, between Leeman and Arrowsmith.
A St John Ambulance spokesman said the woman suffered a serious abdominal injury.
She was taken to Jurien Bay hospital where the RAC rescue chopper was to take her to Royal Perth Hospital.
A police spokeswoman said the other occupants in the car, including several children, were believed to have suffered minor injuries.
