Two dead in separate crashes on NSW roads

Two people have died in separate crashes on NSW roads overnight.

Police are working to identify a man who died after a two-vehicle crash in Sydney's inner west late on Friday night.

The man, believed to be in his 20s, was driving a Mazda hatchback that had collided with a Toyota hatchback on the Princes Highway in Tempe.

Paramedics tried to revive the man but he died at the scene.

The driver of the Toyota, a 54-year-old man, was hospitalised in a serious but stable condition and underwent mandatory testing.

Police established a crime scene and are investigating the circumstances of the crash.

A report will be prepared for the state coroner.

Meanwhile, a woman died after a single-vehicle crash on the Central Coast about 6.30pm on Friday.

Police said the Toyota ute she was travelling in crashed into a tree on a median strip in Somersby, leaving her with critical injuries.

Paramedics treated the 48-year-old woman at the scene but she died.

A man in the ute sustained minor injuries and was hospitalised.

Police are investigating how the crash occurred and will prepare a report for the coroner.
