The Westpac Rescue Helicopter Service say that on Saturday evening they were sent by Ambulance New South Wales to the Nightcap National Park, north of Nimbin after reports that a trail bike rider had fallen heavily while riding in the bush.
The rider, a 50-year-old man, was reportedly suffering from serious chest and back injuries on a remote trail in the National Park.
Local Ambulance Paramedics and Emergency Services attended the scene but had difficulty accessing the patient owing to the nature of the steep and rocky terrain.
The Westpac Rescue Helicopter located the man and winched the Critical Care paramedic and doctor into the scene.
The man was treated and stabilised by the Critical Care Medical Team prior to being carried from the scene and road transported by Ambulance to the Lismore Base Hospital in a stable condition suffering chest and spinal injuries.
People should not be riding in National Park.
