The mother of a girl who missed a flight and vanished has shared her family's heartache as police investigate the 17-year-old's "suspicious" disappearance.
Queensland Police also renew calls for anyone with information to come forward, saying "someone knows something".
Pheobe Bishop was last seen near Bundaberg airport in southern Queensland about 8.30am on May 15 after booking a trip to Western Australia.
She has not been seen or heard from since, with CCTV footage indicating she never entered the airport.
Pheobe's mother Kylie Johnson has been pleading on social media for anyone with information to come forward since her daughter's disappearance a week ago.
"Phee we love you more than you could imagine and we're praying that you come home," she posted on Facebook.
Ms Johnson on Thursday called for her daughter to come home, saying her family needed to "feel your hugs".
"Phee is still missing, our heartache and pain is raw and real," she posted.
"We as a family are trying to hang onto the light of life that is our Free Spirited Gypsy Soul Phee Phee.
"Phee we need you home, we need to hear your sassy voice and feel your hugs."
A Gin Gin property near Bundaberg, where Pheobe was living with two other people, has been declared a crime scene along with a grey Hyundai ix35.
The vehicle is thought to have been used to take Pheobe to the airport and was seized by police, who believe it belongs to a resident of the property.
The property's other residents have spoken to officers and are co-operating with police, Detective Acting Inspector Ryan Thompson said.
No one is in custody and police continue to speak to people who know Pheobe.
Police renewed calls for dashcam or CCTV footage of the vehicle - Queensland registration 414EW3 - near the airport or in the Gin Gin area on May 15.
Det Thompson said public information would be vital for police trying to establish Pheobe's May 15 movements.
"You may have the small piece of information that leads us to finding Pheobe," he said.
"People don't vanish. Someone knows something and we're urging anyone with information to contact police immediately."
Det Thompson on Wednesday told reporters police held concerns for her safety, saying it was out of character for Pheobe not to make contact with anyone.
However, he remained hopeful Pheobe would be found alive.
"Just because we are deeming this suspicious doesn't mean ... anything sinister has happened," he said.
Pheobe is about 180cm tall with a pale complexion, long hair that's dyed red, and hazel eyes.
She was last seen carrying luggage, wearing a green tank top and grey sweatpants.
