This report investigates how Australians are using interactive gambling services and the impact of such online gambling on non-online gambling and gambling related problems. Interactive gambling is a joint term capturing gaming and wagering on the Internet. A research study was conducted over three years and included a nationally representative telephone survey of 15,006 people, an online survey of 4,594 gamblers, interviews with 81 interactive gamblers, and data from gambling help services. This study provides a baseline of who, what, when, why and how people gamble, using interactive technology in Australia.
