Gambling is a popular activity in Australia, but can result in problems for a significant minority. In response, the Australian Government has commissioned the Australian Institute of Family Studies to investigate 'pre-commitment' options for electronic gaming machines. This report is one of a set of three, and focuses on the option of self-exclusion - systems and technology that allow concerned gamblers to bar themselves from venues. It reviews self-exclusion systems in Australia and overseas, design features, effectiveness and barriers of current designs, flexibility and circumvention issues, and avenues for further research. The study draws on a rapid evidence assessment and consultations with key stakeholders in selected government, industry and research sectors in Australia and overseas.
