The manager of the Queensland Racing Integrity Commission's integrity investigations, Tracey Pelling, has resigned to take up a position in Victoria.

She had been in the managing role since February 2018 and was previously Officer-in-Charge of the Queensland Police Racing Crime Squad since 2016.

Pelling is leaving Queensland to take up a leadership position with the Office of the Racing Integrity Commissioner in Victoria.

Commissioner Ross Barnett congratulated Pelling for her service and new appointment.

"Ms Pelling has been involved in a number of significant investigations which have resulted in the arrest of racing industry participants for serious integrity breaches ranging from match (race) fixing to serious animal cruelty," Barnett said.

"She will be an asset to Victorian racing integrity as she has been in Queensland for the past three years."
