Australian wagering service providers (WSPs) are governed by the Interactive Gambling Act (2001). Online wagering in Australia is governed by the Commonwealth through the Act under its responsibility for telecommunications.

The Interactive Gambling Act, enacted in 2001 and subsequently amended in 2017 sets out the rules for companies operating or advertising gambling services in Australia. The aim of the act is to minimise the scope for problem gambling online by limiting the provision of such services to Australian consumers. The Act covers all gambling activity that takes place digitally, such as online, through an app or via telephone.

Sports betting services can only operate if providers hold an Australian domestic licence.  The Act prohibits online casinos and online pokies in Australia. Online in-play sports betting and placing bets on the outcome of a lottery are also prohibited under the Act. Recent changes enacted in 2017 mandated the publishing of a register of licenced interactive wagering providers, as well as new powers to enforce the Act itself.

The Australian Communications and Media Authority (ACMA) monitors and enforces the provisions set out in the Interactive Gambling Act. Any provider that contravenes the provisions of the Act may be warned, fined or referred to law enforcement authorities by the ACMA. In the case of illegal online casinos, the ACMA has the power to request internet service providers to block access to the website.
