A missing teenager has been found dead after officials mistakenly announced that she had been rescued following an eight-day search in the Australian bushland.

Lily Hooper,18,disappeared after setting off for a hike in Nattai National Park,around 90 miles south-west of Sydney,last Wednesday.

Her family raised the alarm after she failed to return home,despite her being in contact with them throughout the day.

A major search operation was then launched in the national park,with police,volunteers and around 100 soldiers.

On Thursday,New South Wales premier Chris Minns was attending a parliamentary hearing when he was handed a note telling him the teenager had been found.
