One of the girls remains in a critical condition in hospital following the single-vehicle crash at Buckaroo, near Mudgee.

Police were told a Toyota Prado containing nine people had travelled to the property off Edgell Lane, near Ulan Road, Buckaroo, shortly after 1pm on Sunday.

Concerns were raised for their welfare this afternoon after they failed to return.

The car was located by a neighbouring landowner in a paddock about 3.15pm and appeared to have rolled a number of times.

All nine occupants of the vehicle were teenaged girls.

One girl was ejected from the vehicle and sustained life-threatening injuries and was found lying near the vehicle.

The other eight occupants managed to escape from the vehicle when it came to rest and all have suffered varying degrees of injuries, none of which are life threatening.

A 14-year-old girl was airlifted to the Children’s Hospital at Westmead, where she remains in a critical condition.

Officers from Orana Mid-Western Police District established a crime scene and are investigating the circumstances surrounding the crash.

Inquiries into the cause of the crash are ongoing with examination of the scene expected to continue for some hours.
