Princes Highway three car collision kills mother and injures four other people on NSW South Coast

A mother has died while her two teenage sons are among four people injured in a three-car crash on the NSW South Coast. 

The 39-year-old woman was killed in the collision on the Princes Highway at Corunna, about 5km south of Narooma, at 4.40pm on Friday. 

A northbound Audi SUV and southbound Toyota Camry sedan had collided on the highway, which caused a white Volkswagen station wagon to crash.

The woman had been driving the Camry and is understood to be the mother of two sons, aged 18 and 15, who were injured in the crash. 

The trio are from Mount Druitt, in western Sydney, and were holidaying along the south-coast. 

The youngest boy was left in a critical condition and the eldest in a serious condition and both were transported to hospital. 

The Audi driver, a 40-year-old man believed to be visiting NSW from South Australia, and his passenger, a 31-year-old woman, were airlifted to another Sydney hospital. 

The woman is stable and the man is in a serious but stable condition.

All five occupants of the Volkswagen were uninjured but the 34-year-old woman driver was hospitalised for observation.

A crime scene was established and police are now calling for witnesses or anyone with dashcam footage.

Investigations are underway and a report will be prepared for the coroner.
