One of the three teenage schoolgirls who ran away from a high school camp on the Bibbulmun Track east has returned safely to Perth.
The girls were on the track in Flynn, 30km east of Roleystone, when they went missing yesterday just before 10am.
They made their way to Koongamia, near Midland, last night and one returned to a friend's house.
Police are continuing a search for the other two but said they had no concerns for their welfare.
Anyone with information on the whereabouts of the girls is asked to call police on 131 444.
