JOHN Doyle will become Victoria's new auditor-general, after serving in a similar role in Canada.

Mr Doyle will replace Des Pearson, who resigned in December after six years in the job.

Mr Pearson has released reports critical of the management of the state's prisons and the operations of Major Projects Victoria, as well as the former government's decision to build the Wonthaggi desalination plant and the Myki ticketing rollout.

Victorian Premier Ted Baillieu said Mr Doyle, who is the auditor-general for British Columbia, would ensure public money was well spent.

Opposition Leader Daniel Andrews said Mr Doyle had a reputation of providing frank and honest advice to the British Columbia government.

''We've got a long tradition in this state of having auditors-general who are fearless critics of this government,'' Mr Andrews said.
