The driver of the car Jackie was travelling in, a 16-year-old who was allegedly driving without a licence, remained in hospital in a critical condition on Saturday.
Police suggested the teenager was speeding when he swerved to avoid a wombat and crashed in the state’s central west, the ABC reported.
The driver’s blue Ford Festiva was flipped onto its roof in the single-vehicle crash on Wollar Road at Munghorn Gap, about 35 kilometres north-east of Mudgee.
The 16-year-old was treated by paramedics before being flown to Westmead Hospital, with life-threatening head injuries.
