The state government will spend its $30 million in carbon tax savings cutting public transport fares across Queensland.

From November 3, tickets for all trains, buses and ferries will drop five per cent, and fares will be frozen in 2015.

Transport Minister Scott Emerson told Fairfax Radio 4BC 22,000 people took part in its two-week survey on fares earlier this month.

"We put up two options to people – a five per cent cut in fares or 1000 additional services," he said.

"[In the survey] 74 per cent of people, a very clear vote, said to cut fares by five per cent."
