Cadaver dogs have been brought in as the search for missing teenager Pheobe Bishop continues.

Queensland Police deployed the canines at the Good Night Scrub National Park just outside of Gin Gin, an hour away from where Pheobe was last seen, on Sunday.

The 17-year-old was last seen leaving a home in Gin Gin, Bundaberg, where she had been living with couple Tanika Bromley and James Wood, on May 15.

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.

Questions remain over exactly why she was living at the house with the pair, but final posts she made to social media before she disappeared suggested the troubled teen had fallen out with her mother and would not return home.

The pair have been questioned by police and were released. No charges have been laid over Pheobe’s disappearance and Daily Mail Australia does not suggest Mr Wood and Ms Bromley were involved.

The update in the search comes after CCTV footage emerged on Facebook of a vehicle at the centre of the police investigation into Pheobe’s disappearance.

Pheobe had been travelling in a silver Hyundai ix35 – which is owned by Ms Bromley – before she disappeared.

Footage showed the vehicle driving through the backstreets of Gin Gin at 10.30am on May 15 – two hours after Pheobe was allegedly dropped off at the airport.

The footage has since been taken down.

On Friday night, police announced they had discovered an item of potential interest in the national park.

Detective Acting Inspector Thompson said at the time the police diving squad searched a creek.

‘Police have subsequently been conducting some searches of the Good Night Scrub National Park in the hopes of finding some evidence in relation to her disappearance,’ he said.

‘There are no specific persons of interest, however, police are following up all avenues of enquiry.’

Police did not say if the item that was found was connected to Pheobe.

On Saturday, police began conducting a land, water and aerial search of the Good Scrub National Park.

‘Police are trying to nail down the timeline to where this vehicle has gone,’ Detective Acting Inspector Ryan Thompson said.

‘We do have associates that are assisting police with our inquiries at the moment, and this is why we’re trying to narrow down that timeline in relation to where Pheobe could be.’

Queensland’s State Emergency Service crews are combing through the bushland, while police divers search waterways.

As officers began a thorough search of bushland, Pheobe’s mum Kylie Johnson released a statement through police in which she described her daughter as ‘feisty’ and ‘the sunflower in a field full of wildflowers.’

The statement said: ‘Who is Pheobe? Phee has always been strong willed and followed her own beat to life.

‘I’ve always called her my ‘Wild Gypsy Banshee’. I’ve told everyone since Phee’s birth that she’s the one I always expected to call me from overseas saying, ‘hey Mumzie mate; I’m in Amsterdam and checking in’.

‘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.

‘Phee loves beyond comprehension and is loyal to her siblings.

‘Phee just loved life; music blaring, she’d say, ‘come on Mumzie, let’s dance.’

‘Hanging with her ‘boys’ even though they all saw her as the little sister to protect.

‘Her friends always knew they would get the truth (and then some if she had an opinion).

‘Phee is the sunflower in a field full of wildflowers. She is an essential part of our lives and we need her home. We need to hear her music, feel her hugs and hear her voice.

‘Pheobe would never not touch base with the people she loves. She would never go this long without contacting someone or anyone.

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

In a further update today, Ms Johnson wrote: ‘I’m praying that the lights of Gin Gin and the world guide you back to me, guide you back us, guide you back to your siblings and our family.

‘Our lives and existence is nothing without you in our lives.’
