Police have suspended physical searches for missing Bundaberg teenager Pheobe Bishop almost three weeks after she disappeared on her way to the airport.

The 17-year-old was last heard from on May 15, when she was due to board a plane from Bundaberg to Western Australia.

Police have confirmed she never made it to the airport.

Crime scenes were declared at the home she shared with two housemates in Gin Gin, and also in a car of interest in the investigation.

Police also began searching a dense patch of bushland in the Good Night Scrub National Park.

Cadaver dogs were deployed and forensics teams in blue dust suits were seen bagging items of interest during the search.

The search was suspended a week ago, with police on Wednesday confirming no physical searches remain ongoing.

“There are currently no physical searches for Pheobe at this stage,” they said.

“However, physical searches will happen as needed and as information is provided.”

Police said, although the physical search has stalled, they were still investigating Bishop’s disappearance.

“Investigations are ongoing and police are continuing to run out several lines of enquiry,” they said.

Bishop’s mother, Kylie Johnson, who has regularly made public pleas for information, recognised the 20th day of her daughters’ disappearance on Wednesday.

“Starting day 20 with you still missing Pheobe,” she said.

“I don’t know if life will ever be the same again? I don’t know if I will ever look at the world the same way that I did before May 15.”
