An elderly woman has died in hospital after she was hit by a car while crossing the road near Newcastle.

The 75-year-old was struck while crossing the road in Wallsend on Sunday morning and was taken to John Hunter Hospital in a serious condition suffering head injuries, but died on Tuesday morning.

Police said the driver was not charged.

The man was last seen leaving his Warwick home on Sunday morning and was reported missing to police the next day.

A passing motorist spotted a Honda Jazz had crashed down an embankment near Tenterfield on the NSW-Queensland border on Monday morning and notified authorities, police said.
