The devastated mother of missing teen Pheobe Bishop has spoken out and said she’s happy to to be under fire as long as Australia keeps talking about her daughter.

Kylie Johnson has been actively promoting the search campaign to find her daughter since the 17-year-old disappeared from the Bundaberg area, in Central Queensland, on 15 May.

Every day, Johnson has been sharing posts on social media to raise awareness about the case, some of which have drawn nasty comments from trolls.

As the search for her daughter entered its 15th day, Johnson penned a new post urging her supporters to not be angry at critics, explaining that they, too, contribute to the efforts to bring her daughter home.

“My posts aren’t public to defend myself or react to negative comments. In fact negative comments also draw conversations and that’s what WE as a FAMILY need to bring Phee home,” she wrote on Friday.

“Hell I will take any conversation if it has My BABY walking down our driveway or calling any of us as a family…

“So please don’t be mad at the Trolls. They have a roll (sic) to play just like the amazing people who honestly just want our Pheobe home.”

Police say Bishop was last seen about 8.30am on May 15 at Airport Dr in Bundaberg, Queensland, as reported to them by her housemates.

The teenager was planning to fly to Perth to spend time with a boyfriend, but never entered the terminal or checked in for her flight.

Bishop had been living with couple Tanika Bromley and James Wood in a home in nearby Gin Gin.

Six days after she vanished, detectives revealed they are treating the case as “suspicious” and set up two crimes scenes - one in Bromley’s car and the other at the Gin Gin property.

The grey Hyundai ix35 was later released after police examined the vehicle and seized items.

Police have repeatedly said Wood and Bromley have been co-operative in the investigation and 7NEWS does not suggest either party is involved in Bishop’s disappearance.

A six-day search of the dense scrub and creek beds at Good Night National Park - involving police, firefighters, and SES crews - was suspended on Wednesday.

Police said the greater Gin Gin area would remain a focus of their investigation and searches would recommence as needed and more information came to light.

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

Anyone with information, vision or sightings of the grey Hyundai ix35 between May 15 to 18 in the greater Gin Gin area is urged to contact police.

Pheobe is described as about 180 centimetres tall, with a pale complexion, long dyed red hair, and hazel eyes.
