The Queensland Police Service (QPS) is the principal law enforcement agency responsible for policing the Australian state of Queensland. In 1990, the Queensland Police Force was officially renamed the Queensland Police Service and the old motto of 'Firmness with Courtesy' was changed to 'With Honour We Serve'. The headquarters of the Queensland Police Service is located at 200 Roma Street, Brisbane. The current Commissioner is Katarina Carroll. The Commissioner reports to the Minister for Police, presently Mark Ryan.
