QUEENSLAND students could be banned from travelling on school buses for up to five days if they repeatedly abuse a plan introduced to keep children safe after Daniel Morcombe's disappearance.

The state government says too many students are blatantly dodging bus fares under a system that was introduced to keep kids safe.

Repeat offenders will now face travel bans, under new guidelines to be rolled out across the state.

Transport Minister Scott Emerson says if a student is banned, they and their parents or guardians will be involved in the process and will be aware they are not allowed to travel on the bus.

"If banned students still attempt to travel and are turned away, it indicates a lack of responsibility on the part of the parents or guardians," Mr Emerson told AAP.

The minister said drivers, operators and the school will also be involved, so everyone will be clear on which student has been refused travel.

"We never said this would be an easy issue to solve, but unlike the previous government we won't stick our head in the sand and will work through the issues," he said.

"While there is no plan to introduce free travel for students, there is already a significant student transport assistance scheme in place and discounts for students."

Repeat instances of unacceptable behaviour such as offensive language or fare evasion may lead to the student being refused transport for up to five school days.

The "no child left behind" principle was brought in after Daniel, 13, disappeared from a Sunshine Coast bus stop in 2003.

A bus that was running late failed to stop for him.

Bus drivers now have to stop for children, regardless of whether or not they have the money to pay their fare.

Mr Emerson said the government was committed to maintaining that principle, but something had to be done to address the rorting.

Asked how practical it was to ask drivers to check lists for banned students, Mr Emerson said he didn't believe too many pupils would be banned.

He said the government had contemplated the prospect of a banned student being targeted in a Daniel Morcombe-type scenario.

Banned students shouldn't be trying to catch the bus in the first place, he said.
