A man and a child have died, and three people have been injured – one critically – in a three-vehicle crash in Sydney's west overnight.
Emergency services were called to the intersection of Mamre and Abbotts roads about 10.40pm (Monday 16 May 2026), and found a small sedan and a van had collided head-on.
A man travelling in the sedan's front-seat passenger seat died at the scene, while a 25-year-old woman and her 15-month-old son in the sedan's rear were critically injured.
They were taken by road ambulance to Westmead Hospital and The Children's Hospital at Westmead, respectively, suffering multiple injuries. The child died some hours after arriving at hospital.
A 21-year-old learner-licence holder driving the sedan, and the driver of the van, a 45-year-old man, escaped with relatively minor injuries. Both men were taken to Liverpool Hospital for assessment and mandatory testing.
Police have been told immediately before the major impact, the sedan and a ute had collided, before the sedan continued and was involved in the crash with the van. The male driver of the ute escaped unharmed.
Officers from Nepean and Liverpool City Police Area Commands attended the scene, assisted by Highway Patrol and specialists from the Crash Investigation Unit.
Inquiries are continuing.
