The authority said the nine all breached the Interactive Gambling Act 2001 by offering services to Australian players without a licence.
As such, the ACMA contacted Australian internet service providers to block access to Stay Casino, Bambet, Dazard Casino, Level Up Casino, Rocketplay Casino, Wild Tornado Casino, Cobra Casino, Cobra Bet, Casinority and Pokies Lab.
The latest round of blocking orders mean that since the ACMA made its first blocking request in November 2019, a total of 481 illegal gambling websites have been blocked.
In addition, more than 160 illegal services have also pulled out of the Australian market since the ACMA started enforcing new illegal offshore gambling rules in 2017.
“The ACMA is reminding consumers that even if a service looks legitimate, its unlikely to have important customer protections,” the ACMA said. “This means Australians who use illegal gambling services risk losing their money.”
Last month, the ACMA also issued blocking orders against Golden Crown Casino, Sol Casino, PowBet, ExciteWin, Sportaza and Gamble Online.
The six websites were also deemed to have breached the Interactive Gambling Act 2001.
