Motorcyclist killed in fiery highway crash

A motorcyclist has been killed after he was thrown from his bike in a fiery crash on the NSW mid-north coast.

A number of witnesses rendered first aid after the head-on crash with a Holden Commodore on the Pacific Highway at Korora, near Coffs Harbour, on Wednesday afternoon.

But the man, aged in his 50s, died at the scene.

Other bystanders extinguished the man's motorbike, which burst into flames from the crash.

Police said the Commodore driver was uninjured but taken to hospital for mandatory blood and urine tests.
