An elderly woman has died following a collision in Bannockburn earlier this month which already claimed the life of a man.
The 79-year-old male driver of a Nissan sedan died at the scene of the 12 April crash, which left his female passenger with life-threatening head injuries, police said.
An ambulance helicopter airlifted the 75-year-old female passenger to the Royal Melbourne Hospital, but she died of her injuries on Anzac Day.
Police said the sedan, travelling south west on Clyde Hill Road, collided with a 4×4 utility towing a caravan on the Midland Highway at 4.30pm.
An ambulance took the occupants of the utility, a man and a woman and a small child to a Geelong hospital with minor injuries.
