Two Victorian Building Authority employees have been charged with criminal offences relating to the assessment of builder registrations in exchange for a financial benefit.

VBA Commissioner and CEO Anna Cronin says the authority referred suspicious activity to the Independent Broad-based Anti-corruption Commission in June last year and has aided the investigation.

Last week the authority was told two employees had been charged and IBAC was investigating a third.

“The employees involved have been stood down by the VBA with immediate effect,” Ms Cronin said. “The VBA is now reviewing any impacts of this alleged activity to ensure the integrity of our systems.”

IBAC says it searched a number of premises last Wednesday and actions against “key persons of interest” resulted from its investigation into corruption allegations.

The corruption watchdog and the VBA say they will not comment further while the investigation continues.
