NSW Police said in a statement she passed away in hospital early on Sunday.
Officers from Port Stephens-Hunter Police District will prepare a report for the information of the Coroner.

NSW Ambulance paramedics treated her at the scene before the Westpac Rescue Helicopter critical care medical crew arrived and placed her in an induced coma.
She was airlifted to John Hunter Hospital in a critical condition.
A NSW Police spokesperson said no charges had been laid.
