Two male teenagers were taken to hospital on Thursday afternoon after their quad bike rolled in New South Wales. Police and emergency services were called to a property, about 50 kilometres north-west of Sydney, at about 12pm following reports of a quad bike incident.

One of the boys reportedly suffered serious head injuries while the second suffered multiple fractures to his lower leg.

The CareFlight medical crew assisted NSW Ambulance paramedics in treating the teenagers at the scene.

The two boys were later transported to Westmead Hospital for further treatment.
