The Australian Communications and Media Authority directed all Australian internet service providers to block eight unlicensed gambling websites on 18 March 2026. The sites blocked were Cuntspin, Frumzi, Greatwin, MyStake, Oh My Spins, RetroBet, The Dog House 2 Slot, and Viperwin. All eight offered casino-style games including slots to Australian customers without holding a valid Australian licence.
The March action brings the cumulative total of blocked illegal gambling and affiliate websites to 1,564 since ACMA issued its first blocking request in November 2019. That figure has risen sharply in recent months: the total stood at 1,296 in August 2025 and 1,455 in December 2025. At least 225 unlicensed operators have also voluntarily left the Australian market since ACMA's enforcement program began.
Tabcorp Fined for In-Play Betting
In a separate enforcement action, ACMA issued a $158,400 infringement notice to Tabcorp Holdings in January 2026 for accepting online in-play sports bets in breach of the Interactive Gambling Act 2001. In-play betting online is prohibited under Australian law, though it remains legal at physical venues and via telephone. Tabcorp's fine is one of a series of penalties ACMA has issued to licensed operators in recent months, alongside actions against Betfair ($871,660 in July 2025) and PointsBet ($500,800 in May 2025).
ACMA has also been active on social media enforcement. In January 2026, the regulator investigated influencers who used Australian Open branding to promote offshore gambling sites, contacting Meta to remove the content. Fines for facilitating links to illegal gambling can reach $2.5 million under the Interactive Gambling Act.
Polymarket and Prediction Markets
In August 2025, ACMA formally declared prediction market Polymarket a prohibited service after confirming it accepted Australian bets without a licence and offered in-play betting. Blocking orders were issued following a formal letter to New York-based parent Adventure One QSS. The Polymarket case signals that ACMA's enforcement scope extends beyond traditional sportsbooks to newer wagering formats.
What This Means for Punters
If a betting site you previously used has become inaccessible, ACMA may have directed ISPs to block it. Using an unlicensed offshore site carries real risks: no access to Australian dispute resolution, no compliance with local responsible gambling requirements, and no guarantee your funds are held securely. ACMA maintains a public register of licensed interactive gambling providers, which is a reliable first check before depositing with any operator.
