Australia Blocks Polymarket and Other Websites
The Australian Communications and Media Authority (ACMA) has ordered the blocking of the prediction market platform Polymarket following an investigation by news outlet “Crikey,” which revealed targeted promotion to Australian users.
Why Polymarket Was Blocked
The company is accused of violating the Interactive Gambling Act 2007 and operating without a local license.
The investigation began in May after “Crikey” reported that Polymarket had paid Australian Instagram and TikTok influencers to promote betting on the 2025 federal elections.
List of Blocked Websites
Alongside Polymarket, ACMA has also blocked other illegal online casinos and affiliate platforms. In August 2025, the list included:
- Slot Mafia (N1 Partners)
- Spinanga (7Stars Partners)
- Top Aussie Pokies
Updated ACMA Data
According to official data, blocking websites is just one of the measures used to protect Australians from illegal gambling services.
Since November 2019, ACMA has requested the blocking of 1,296 illegal gambling and affiliate sites. Since 2017, around 220 services have completely exited the Australian market.
User Risks
ACMA warns that even if a gambling site appears legitimate, it may lack the necessary consumer protection measures.
This means that users betting on illegal platforms risk losing their funds with no legal recourse to recover them.
How to Check a License
You can verify whether a bookmaker or casino is licensed to operate in Australia by checking the official register. The ACMA website also provides guidance on protecting yourself from illegal operators and filing a complaint against an unlicensed service.
Blocking Statistics Table

| 2017–2018 | – | 220* |
| 2019–2025 | 1,296 | – |
*According to ACMA data since the introduction of new regulations.
Conclusion
ACMA’s actions aim to tighten control over online gambling and protect users. Blocks like those imposed on Polymarket, Slot Mafia, and Spinanga are part of a broader campaign to shut down illegal gambling services in Australia.
