A bushwalker, who was missing in Royal National Park on Sunday, was found safe and well just before 11pm.
The Engadine woman, 69, intended to set off at 2.30pm and walk the Uloola Track from Waterfall to Lady Carrington Drive.
A police spokesman said arrangements were made for her to be picked up at Lady Carrington Drive about 4pm, but she failed to make the rendezvous.
"Police and family held serious concerns for her welfare," he said.
"Officers from Sutherland Shire Police Area Command with the assistance of PolAir, Dog Unit, NSW Ambulance paramedics, and NSW Rural Fire Service commenced an extensive search of the area.
"About 8.30pm, extra resources were deployed to assist with the search.
"About 10.45pm, the woman was located in the Royal National Park safe and well.
"Police would like to thank the media and public for their assistance."
Police issued a reminder to bushwalkers to plan their journeys ahead of time, ensure sufficient food, water and warm clothing are always taken, and to stay put and remain together when emergency services have been contacted in the case of an emergency.
