Modern, commercial fantasy sports came to Australia in 2001. It has since grown into a significant and accepted part of the Australian sporting and gambling landscape. Fantasy sports’ mainstreaming has been relatively uncontroversial. It has found its place within Australia’s regulatory regimes absent the controversy and disputes that has plagued it in the USA. Its operators have been licensed and there have been no significant challenges to the products they offer. This is not to say that fantasy sports are without their regulatory and legal issues in Australia. On the contrary, such issues abound.
