The union fighting for better pay for Brisbane bus drivers has accused the council's transport chairman of misleading people with "fictitious" driver salaries.

On Thursday Fairfax Media reported Brisbane City Council's Public and Active Transport chairman Adrian Schrinner revealed the average salary of a Brisbane bus driver was $68,398, or $34.61 an hour.

Rail, Tram and Bus Union secretary Tom Brown said the figure was fictitious, as it included overtime and special-event pay.

"To factor the overtime and stuff into people's pay is a no-no because that comes and goes," Mr Brown said.
