Girl, 17, missing for 10 days after failing to board flight to meet her boyfriend

The worried family of a 'sassy, feisty and strong-willed' teenager who has been missing for 10 days in Australia after failing to board a flight have spoken out.

On May 15, Pheobe Bishop was expected to fly from her home in Bundaberg, Queensland, to Western Australia via Brisbane to meet up with her boyfriend.

CCTV footage, however, showed that the 17-year-old never entered the terminal.

Instead, she was last seen at Airport Drive in Bundaberg at 8.30am ten days ago.

"She was last seen carrying luggage and wearing a green tank top and grey sweatpants," the missing persons warrant says.

Police confirmed that Pheobe was not staying with family members at the time of her disappearance and, instead, was with two people 'she has been living with for a while' in Gin Gin, west Bundaberg.

Pheobe's mum Kylie Johnson said on social media on Friday (23 May) that it was 'getting harder to breathe' without her daughter, who she described as 'strong-willed and [has] followed her own beat to life'.

"Phee is the sunflower in a field full of wildflowers. She is an essential part of our lives and we need her home," the distraught mum said in a statement on behalf of the family.

"We need to hear her music, feel her hugs and hear her voice. You can't tame Phee's spirit, empathy or fight for life. She is sassy, feisty and loves harder than anyone I've ever meet.

"We are appealing to anyone who may have heard from Phoebe, or anyone who has information about where she may be, to please contact police."

ABC Australia reports that the property Pheobe was staying at in Gin Gin has now been declared a crime scene.

Police said that Pheobe was living there with local couple Tanika Bromley and Mr Wood, the two people who reportedly drove her to the airport.

Mr Wood, who was said to have been questioned by police, issued an appeal of his own to help find Pheobe.

"Any little bit of information can help, please if you know something, please contact her family," he wrote on Facebook. "If you know where she is and can give her family a legit address to bring her home or make contact with her, you can (have) my fishing boat as a reward, 15 ft alloy tinnie with trailer and all."

Neighbour Shari Loughland told the outlet that she had been staying at the address 'for a few weeks, up to a month or two'.

''They moved in late October or November, and then it's just gotten more and more cluttered with rubbish," she said. ''It was for sale... I don't think they actually own it."
