A Queensland bus driver has been sacked after a five-year-old girl was left alone and trapped on the vehicle for several hours, sparking a major search.

Ross Belsham hit out at the decision on Thursday, telling Nine News even though he was responsible, several factors contributed to Alyssa Jayde Langdon being unnoticed on January 22.

Her mother Bobbie Langdon claimed she met the bus at the stop where her daughter was supposed to get off.

It was believed the young girl caught the bus but fell asleep on one of the back seats on the journey home, out of sight of the driver and other passengers, police said.
