ONE man has been seriously injured and another has been killed after two four-wheel-drives crashed north of Narrabri.
The two men were thrown from a Toyota Landcruiser when it lost control and rolled onto its roof shortly before 7.30pm on Tuesday.
Police said the vehicle then rolled onto the men, killing a 36-year-old at the scene near the intersection of Homestead Road and Ten Mile Lane at Edgeroi.
A 38-year-old man suffered head injuries and was freed by emergency services and treated at the scene by paramedics.
The Westpac Rescue Helicopter was later tasked and airlifted the man from Narrabri hospital to John Hunter Hospital in a serious but stable condition.
A 42-year-old man, who was behind the wheel of the second Landcruiser, was taken to hospital suffering shock but was later released.
The Oxley Crash Investigation Unit and Barwon police are investigating the circumstances surrounding the crash and a report will be prepared for the coroner.
