How online casino domain blocking works

In Australia, blocking online casino domains is one of the key tools in the fight against illegal slots and gambling. This measure is applied by the Australian Communications and Media Authority (ACMA) based on the Interactive Gambling Act 2001 (IGA).

1. Grounds for blocking

ACMA initiates blocking if the operator:
  • provides access to prohibited games (including slots) for real money;
  • touts illegal gambling services for Australians;
  • does not comply with termination requirements after formal notification.

2. Blocking Procedure Steps

1. Monitoring and detection - ACMA conducts regular analysis of sites and advertising on the Internet.
2. Official notification - the operator receives a written request to stop providing prohibited services.
3. Non-compliance - If ignored, ACMA requests ISPs to block the domain.
4. Technical blocking - the provider restricts access to the site at the DNS, IP or URL level.

3. Who is obliged to block

Internet Service Providers (ISPs) - are required to restrict access to the domain in Australia.
Hosting providers - in some cases may require the removal of content.

4. Blocking features

Blocking visibility: when users try to access the site, they see a page with an ACMA notification that the resource is unavailable.
Terms: blocking is introduced after the expiration of the period allotted for voluntary termination of activities (usually 28 days).
Bypassing locks: formally illegal, but in practice possible via VPN; ACMA is constantly updating the list of locks, including new site mirrors.

5. Effectiveness of the measure

According to ACMA, from 2017 to 2024, more than 900 domains related to illegal slots and casinos were blocked.
Blocking reduces the availability of prohibited games, but does not completely eliminate the possibility of access through technical bypasses.

6. For the players

Getting a domain on the blocking list means that the operator is recognized as a violator of the law.
Playing on mirrors or via VPN deprives the player of legal protection and increases the risk of loss of funds.

Final conclusion

Blocking online casino domains in Australia is an effective ACMA tool to restrict access to illegal slots, but not absolute protection. It serves as a warning to players and a signal that the operator has violated the law.
