The driver of the car, a 26-year-old Clovelly Park woman, was not injured and is assisting police as they investigate the incident.

The Advertiser understands the car, a Honda, was turning right from Malpas Road onto Main South Road while the motorcyclist was heading southbound on Main South Road.

Police advise motorists to avoid Main South Road for southbound travellers from the Thomas Road and Branson Road intersection, and roads are expected to be closed for some time as major crash investigators attend the scene.
