The Office of Police Integrity (OPI) was the Australian state of Victoria independent police oversight and anti-corruption agency established by the Victorian Government in November 2004. OPI ceased operation on 9 February 2013 and was replaced by the Independent Broad-based Anti-corruption Commission (IBAC). OPI's official role was to detect, investigate and prevent police corruption and serious misconduct and to ensure that police members had regard to the human rights set out in the Victorian Charter of Human Rights and Responsibilities.
