A FIVE-year-old girl is fighting for her life after a car crash on the Pacific Highway south of Broadwater on Monday afternoon.
Just before 3pm, the driver of a late model Holden Barina travelling north lost control of the vehicle and crossed the southbound lanes before hitting a tree.
The force of the crash was so great the girl was thrown from the car, suffering critical injuries.
She was quickly flown by the Westpac Life Saver Rescue Helicopter to Lismore Base Hospital and was later transferred to Brisbane's Mater Children's Hospital, where she last night remained in a critical condition.
An eight-year-old boy and the 49-year old driver, believed to be the children's' grandmother, were both driven by ambulance to Lismore Base Hospital in a stable condition.
It was not known where the children or the driver of the Victorian-registered vehicle were from.
NSW Ambulance Service Brunswick Valley Zone Inspector Greg Powell said the girl had sustained serious head and abdominal injuries.
"CPR was commenced by two nurses who came across the incident. Resuscitation was then taken over by ambulance paramedics before the helicopter arrived and airlifted the unconscious patient to hospital," Insp Powell said.
Insp Powell said the accident was "quite traumatic" for emergency services and bystanders who witnessed the crash.
"Trauma support was offered to all bystanders at the scene," he said.
Westpac helicopter crewman Mark Sewell said the team worked quickly in an effort to give the girl "every chance" of survival.
"We landed on the highway and did a hot load (without stopping the rotor) because of the urgency," he said.
"Then we did a hot unloaded at the helibase and got the patient straight into the ambulance."
The crash shut down the Pacific Highway for more than two hours yesterday afternoon as officers from the NSW Police Crash Investigation Unit tried to determine the cause of the crash.
