ACMA Moves to Block MyStake and Linked Offshore Gambling Sites in Australia

Australia’s communications regulator has formally called on internet service providers to block access to MyStake after determining that the platform breached national gambling regulations.

The action is part of a wider crackdown targeting offshore operators that provide gambling services to Australian users without holding the required local licences. Authorities have also extended the latest enforcement measures to several additional brands connected to Curaçao-based companies.

The Australian Communications and Media Authority (ACMA) launched an investigation under the Interactive Gambling Act 2001 and concluded that MyStake had been offering services illegally to Australian customers. The platform is run by Santeda International BV, a Curaçao-based company, and was identified as one of multiple offshore operators acting unlawfully within the Australian market. This development reflects the regulator’s continued focus on unlicensed international gambling platforms.

In addition to MyStake, the ACMA has requested blocks on other websites, including RetroBet and Viperwin. Two further brands—Oh My Spins and Frumzi—were also targeted in the latest enforcement action. These platforms are reportedly owned by Rabidi NV, another Curaçao-based operator. Notably, Rabidi NV had previously been issued a formal warning by the ACMA in March 2024 for providing unlicensed gambling services to Australian users. The latest move indicates that the regulator is intensifying efforts against repeat offenders and affiliated entities.

The ACMA emphasized that website blocking remains a central tool in its broader enforcement strategy. According to the regulator, such measures are designed to reduce consumer exposure to illegal online gambling services and enhance user protection. The authority also highlighted the scale of its compliance efforts since the introduction of stricter rules in recent years.

The ACMA stated:“Website blocking is one of a range of enforcement options to protect Australians against illegal online gambling. Since the ACMA made its first blocking request in November 2019, 1,564 illegal gambling and affiliate websites have been blocked.

Over 225 illegal services have also pulled out of the Australian market since the ACMA started enforcing new illegal online gambling rules in 2017. The ACMA is reminding consumers that even if a service looks legitimate, it’s unlikely to have important customer protections. This means Australians who use illegal gambling services risk losing their money.”

This latest action follows a series of similar regulatory steps. In August, the ACMA moved to block Polymarket after finding it in violation of the 2001 legislation. In November, seven additional websites were subjected to blocking orders, while five more were targeted in July.

Separately, a report released by GAMRS at the end of 2025 alleged that MyStake had also been targeting players in the United Kingdom, alongside other black market operators. The report estimated that Santeda International BV’s network of brands generates an annual turnover of approximately €4.17 billion (£3.51 billion), underscoring the scale of the offshore gambling ecosystem under scrutiny.
