A woman in a "serious condition" is being airlifted to Sydney after falling 15 metres from a rock ledge at a popular North Nowra walking track.
The woman in her 40s sustained a fractured left femur and fractured left pelvis after falling from a cliff edge at The Grotto walking track, Yurunga Drive.
Residents at Yurunga Drive heard the woman "crying for help" and emergency services were called to the scene just before noon on Wednesday.
Shoalhaven Ambulance Inspector Nathan O'Brien understands the woman is an "experienced rock climber" and was alone at the time of the incident.
He could not confirm how long the woman had been at the scene before she was attended to.
"We understand she was by herself at the time, and her partner has had an understanding of where she was, but she didn't come home," said Inspector O'Brien.
"So he's gone looking for and found her.
"A fractured femur is quite serious. She is in a serious condition but we can't comment any further than that."
Inspector O'Brien said the woman was given pain relief and was immobilised by a walking party on the ground while they waited for the helicopter to stop at the Shoalhaven Ski Park.
The woman was airlifted to St George Hospital in Sydney with a doctor and paramedic.
Over a dozen emergency services officers including a Toll NSW Ambulance Rescue helicopter, Bomaderry paramedics, Shoalhaven fire and rescue, and police officers attended the scene.
A Special Casualty Access Team (SCAT) paramedic attended the scene due to the vertical access issues at the cliffs edge.
