The ICAC was established by statute in 1988 and began operating in March 1989. Its creation was a reaction to a significant decline in the public sector's credibility. The ICAC has been mandated to expose and minimize the incidence of corrupt conduct in the New South Wales public sector. The ICAC uses three tools to achieve its objectives: investigation, which aims to expose the facts in cases of suspected public-sector corruption; corruption prevention, which involves scrutinizing public-sector systems to determine whether they have a propensity to permit or encourage corrupt conduct; and education, which involves educating public employees and the community in general about what is involved in the ethical performance of public-sector jobs. In its research efforts, the ICAC has identified the following categories of corruption risk factors: opportunity, cultural acceptance, little fear of detection, and lack of leadership and support. This paper describes specific measures that have been undertaken to achieve cultural change that promotes ethical public service; efforts in the development of codes of conduct; legislation to enhance the reporting of public corruption; the prevention of corruption in procurement processes; and the benefits of good governance for business, the government, and the community.
