THE RAC rescue helicopter joined the Department of Fire and Emergency Services on Monday to rescue a man injured after climbing in a quarry.
Emergency crews rescued the rock climber, believed to be in his 40s, who fell at 11am.
He was stranded halfway down the cliff face.
The man fell 10m and broke his arm on a granite outcrop in the quarry located near the intersection of Coulston and Hudman roads in Greenmount.
The helicopter arrived about 12.30pm.
The man was transferred to the Royal Perth Hospital this afternoon.
Career Fire and Rescue Service firefighters and State Emergency Service volunteers used vertical rescue equipment to free the person.
