Toddler Chloe Campbell and her mother have been interviewed by detectives trying to piece together how the three-year-old disappeared from her Childers home.
Police are not discounting the possibility Chloe may not have been kidnapped, and instead may have simply just wandered away on Thursday night.
The shy little girl has clung to her mother Tammy O'Donnell's side since her return at in the early hours of Saturday, 42 hours after she disappeared from the lounge room of the family home, where she was sleeping with her siblings.
Her disappearance sparked a massive police hunt before police found her in the Childers showground across the road from her home.
A Queensland police spokesman said detectives would interview Chloe and Ms O'Donnell at Childers police station.
Earlier, Inspector Kevin Guteridge said investigators would consider if she had wandered off.
"We have no idea as to how she came to be here," Insp Guteridge told reporters.
"We are looking at every aspect of that and maintaining a very open mind.
"It's an absolute miracle that she has returned to us.
"It's one of those dreams that came true ... the greatest possible outcome for everyone."
Ms O'Donnell told reporters she was "overjoyed" when she was reunited with Chloe at the Bundaberg Base Hospital, where she was examined and later released.
"She opened her eyes a little bit and (said) 'Mummy want to go home now' and passed out," the mother of four said.
"I was just in tears. I didn't care if she woke up or not and then I just laid on the bed with her and gave her cuddles for a while and then we just came home to let everyone know."
Chloe sat on Ms O'Donnell's knee and held her tightly as she spoke.
"I've had her like this since I've been here this morning. She's been near me. I haven't left her side," she said.
"I'm still in a little bit of shock by what's happened but I've got my little girl back. I'm happy."
Investigations are continuing.
