A four-year-old NSW girl who witnessed her mother roll a quad bike before calling triple-zero will be formally thanked by police on the state's mid north coast.
The girl saw the accident unfold on a property north of Taree about 1.30pm Tuesday.
Her 35-year-old mother was riding a caged quad bike but lost control and rolled several times down a hill.
By the time the vehicle came to a stop, she was pinned by the leg and suffered a fracture and several serious lacerations.
Police said the young girl then climbed down the embankment and tended to her mother before returning to the home and calling emergency services.
The woman was airlifted to John Hunter Hospital in a stable condition after spending two hours trapped at the scene.
"The girl is being cared for by relatives while her father returns from interstate," police said in a statement.
"Officers from Manning Great Lakes Local Area Command will formally acknowledge the child's quick thinking and life-saving actions."
Emergency services earlier said the girl had been involved in the accident. However, police later clarified her role as a witness.
