Pheobe Bishop's mum has shared the heartbreaking question her young son asked as the search for his missing teenage sister continues.
The 17-year-old was last seen on May 15 leaving a home in Gin Gin near Bundaberg where she had been living with couple Tanika Bromley and James Wood.
Detectives believe the pair drove Pheobe the 40 minutes to Bundaberg Airport where she was supposed to board an 8.30am flight to Brisbane and then onto Perth where she planned to meet up with her boyfriend.
Two crime scenes were declared including the property in Gin Gin and the silver Hyundai ix35, which was used to drop the teenager off at the airport.
Queensland Police have searched bushland at the Good Night Scrub National Park, about an a hour away from where she was last seen, for the last two days and had cadaver dogs at the scene on Sunday.
