Daily Mail Australia understands the officer attempted to stop the trail bike rider at the scene, who was allegedly speeding away from police.
The senior constable was rushed to the nearby John Hunter Hospital by air ambulance, where his condition is said to be serious but stable.
The rider, 19, is being treated for head, leg and pelvis injuries after he was ejected from the trail bike.
He was also taken to hospital for non-life threatening injuries and remains under police guard.
Inquiries have since revealed the trail bike was unregistered.
