A St John spokesperson said they were called to the incident about noon on Thursday.
A helicopter and an ambulance were sent to the scene. The person was transported to hospital with moderate injuries.
A reporter at the scene said the helicopter hovered above the area for about 15 minutes before winching the person, who was on the side of a cliff, to safety.
It is understood the person fell. Another person was seen further down the bank, assisting emergency services.
