Police are investigating a hit and run on a dirt track at Wallsend.
A 28 year old man was walking with three mates in bush near Bulkara Street, when he was struck by a 4WD.
Police say the driver failed to stop and fled from the scene.
The victim suffered chest injuries and had to be winched out by the Westpac Rescue Helicopter Service.
It was the final mission for the chopper's Bell 412 aircraft.
The iconic yellow helicopter has been retired from service, and will now head to Germany to help fight bushfires.
