The state government has frozen public transport fares across Queensland for 2015, in a move destined to be seen as an election sweetener.

Transport Minister Scott Emerson announced on Monday that a 2.5 per cent annual fare increase scheduled for January would be scrapped.

"Last year we cut fares by five per cent - that was the first time in Queensland history that we saw a state-wide cut to fares, and this year there's a freeze to fares," he said.

"We've said moving forward fares would be 2.5 per cent [annually] – that's below the CPI."
