The online gambling industry remains one of the strictly regulated industries in the Australian market. Gambling websites in Australia rapidly keep shifting, leaving many punters wondering about the effectiveness of emerging online slot machines or pokies and online betting services. The strict blocking requests reflect the continuous popularity of online casinos and online sports betting in Australia. However, to protect Australians against illegal sites, the Australian Communications and Media Authority (ACMA) started enforcing new website blocking services on websites that promote illegal online content. 

Understanding the range of enforcement options and the information about online gambling

Websites will protect Australians from illegal gambling websites. Hence, let’s have a detailed analysis of the ACMA domain blocking system and understand what the regulated interactive gambling service has in store for Australians. 

What Is the ACMA and Its Role in Online Gambling?

The Australian Communications and Media Authority (ACMA) enforces the Interactive Gambling Act 2001, which requires the Australian Internet Service Providers (ISPs) to un-license illegal gambling and affiliate websites or block access to illegal gambling services in Australia. The ACMA primarily protects the Australian consumers by blocking illegal websites, enforcing the law, disrupting operators, regulating advertising and managing self-exclusion. In short, it works to impose important customer protections to ensure the quality and integrity of gambling services in Australia.

The Australian Communications and Media Authority (ACMA) enforces the Interactive Gambling Act 2001, which requires the Australian Internet Service Providers (ISPs) to un-license illegal gambling and affiliate websites or block access to illegal gambling services in Australia.

The latest sites blocked include C***spin, Frumzi, Great Win, MyStake, Oh My Spins, RetroBet, The Dog House 2 Slot, and Viperwin. When these gambling sites get blocked, online casinos typically launch mirror sites or new domains that are exact replicas of the original illegal websites. The ACMA made its first blocking request in November 2019, blocking over 1,564 illegal gambling and affiliate websites. This unlicensed regulated interactive gambling act reminds the customer that if any service looks legitimate, then it is unlikely to have important customer protection options. 

Understanding Mirror Sites in Online Gambling

Mirror sites

🪞 Mirror Site

A mirror site is an exact replica of an existing website or set of files, hosted on a different server and often under a different URL. These are used to distribute network traffic, improve access speeds for global users, or provide alternative access points if the primary domain is censored or blocked.

The online gambling operators create mirrors to allow the casinos to bypass the ISP-level DNS blocks, enabling Australians to regain access using a different or alternative web address. These sites often use automated systems or AI to generate the domains and remain on shared or rotating IP addresses to avoid IP-based blocks.  

The legality of mirror sites is still restricted, but these sites operate in a regulatory grey area, meaning that players will have no legal recourse from the ARCMA if disputes arise over the winnings or fraud. However, mirror sites pose significant safety concerns for Australian players, including the SSL encryption and maintaining the same certified Random Number Generators as the original sites to ensure fair play. 

Impact of Domain Blocking on the Gambling Industry

The market, since the ACMA’s domain blocking, has immensely disrupted illegal online content, forcing over 220 unlicensed operators to exit the Australian market. In an interview, the ACMA member responded to disruption as their underlying aim was to protect and minimise the harm to Australian consumers. The interview also revealed the challenges ACMA countered during the enforcement, such as the high level of anonymity and ease in altering the illegal digital presence. 

Although the illegal casino sites remain resilient, the enforcement has impacted the gambling industry greatly, as it resulted in the channelisation of players, implementing circumventive techniques, shifting towards deeper control and imposing user awareness regarding such illegal activities. However, the domain blocking can not be considered as a preventative or alternative measure; it acts as a vital component regarding the enforcement options of civil offences, including ad restrictions and legal actions.

FAQs

What can the ACMA not do?
The ACMA cannot force a regulated entity to enter into an enforceable undertaking. While they have broad powers to issue warnings, fines, and remedial directions, an enforceable undertaking is a voluntary commitment made by the entity and accepted by the ACMA.
What happens if you are caught online gambling in Australia?
Under the Interactive Gambling Act 2001, it is the operators who face criminal charges and civil penalties for offering illegal services. There is no offence for individual Australian citizens who choose to play at offshore sites, though they lose all local consumer protections.
What type of gambling is illegal in Australia?
It is illegal to offer online casino games (such as blackjack and roulette), real-money pokies, online poker, and “in-play” sports betting to customers located in Australia. Licensed providers may only offer wagering on sports, racing, and lotteries.
What apps are included in the Australian under-16 social media ban?
As of late 2025 and 2026, the age-restricted list includes Facebook, Instagram, TikTok, Snapchat, X (Twitter), Reddit, Threads, Twitch, Kick, and YouTube. Apps focused on messaging (WhatsApp, Messenger), education (Google Classroom), and gaming (Roblox) are currently excluded.
Can you gamble at home in Australia?
Yes, gambling at home is legal provided you use a service licensed in Australia (such as Tabcorp or Sportsbet) for permitted activities. Playing at unlicensed offshore casino sites is not a crime for the player, but it carries significant financial risk.
