Distressed mother Bobbie Langdon contacted authorities yesterday afternoon when her daughter Alyssa Jayde New did not return home from Jimboomba State School, south of Brisbane.
Police immediately began the search for the missing child, who was eventually found around 7:30pm at the bus depot in Logan, Queensland.
The Queensland Police Service said the child had been found safe and well after falling asleep on the bus.
Ms Langdon told ABC, 'My daughter will not be attending Jimboomba State School anymore and Logan coaches will be hearing from my family lawyer.'
A spokesman for Logan Coaches confirmed the matter was being investigated but refused to elaborate further.
Queensland Premier Annastacia Palaszczuk said bus companies needed to ensure its vehicles were empty before going to the depot.
'I think it would have been a horrific few hours for the parents not knowing what happened to their daughter, thankfully she has been found safe,' Ms Palaszczuk said.
