The father of a five-year-old girl who was left on a Queensland school bus for four hours has thrown his support behind the driver, who was fired over the incident.

Bus driver Ross Belsham, 79, was informed on Tuesday that his employment with Logan Coaches had been terminated despite evidence to suggest a series of errors by numerous people resulted in the girl being left behind.

It is believed Alyssa sneaked onto the bus on January 22 as Mr Belsham did his regular pick-up run from Jimboomba State School.

Mr Belsham had done his usual sweep of the bus and dropped off his other passengers, not knowing Alyssa was asleep in the back of the vehicle.

The little girl was only rescued when she awoke and began banging on the bus windows at the company's terminal.

Alyssa's father Adam New, 37, said while it was "disturbing" his daughter was left on the bus, he didn't believe Mr Belsham should have lost his job.

"All the kids speak very highly of Ross. He takes very good care of the kids, always has taken very good care of the kids," Mr New told 9NEWS.

"I believe he had some wrongs in what he did, but to lose his job and be publicly shamed in the way that he has, is not acceptable at all. He should still have his job, he should still be carrying the kids to and from school."

"As Alyssa's father I don't believe he should've been sacked.

"If they checked the bus, Alyssa would've been found and it wouldn't have been as big a deal as what it is today."

Mr New said Alyssa was coping well despite the ordeal.

"The potential for Alyssa to be harmed health-wise was significant," Mr New said.

"If it had have been an extremely hot afternoon she could've been hospitalised or potentially worse.

"She's doing well, she's happy. If you talk about buses she gets a bit standoff-ish.

"It has most definitely had quite an impact on her, which is understandable. But in general she's pretty good."

Yesterday, Mr Belsham told 9NEWS his firing would have a significant impact on his life.

"I've lost my job and I don't think I've had a fair run. That's the end of my life, unless somebody out there wants to give me a job," he said.
