Gambling websites Pokies Parlour and Ninja Spins were both ruled to have been operating in breach of the Interactive Gambling Act 2000, as were affiliate sites Pokies Online Casino, CasinoAus, Australian Casino Sites and AU Online Casino.
In response, the ACMA requested Australian internet service providers (ISPs) block access to all six sites.
Since making its first blocking request in November 2019, the ACMA said it has blocked 426 illegal gambling websites in the country.
More than 160 illegal services have also pulled out of Australia since the ACMA began to enforce new illegal offshore gambling rules in 2017.
“Website blocking is one of a range of enforcement options to protect Australians against illegal online gambling,” the ACMA said. “Website blocking provides a valuable opportunity to alert the public to illegal gambling services through the messaging that appears when there is an attempt to access the site.”
The latest blockings come after the ACMA last month also orders to halt access to another 12 gambling websites. These sites were Zebet, Zeturf, Slot Vibe, Arlekin Casino, Johnnie Kash Kings, Lucky Star, Horus Casino, 21 Dukes, Tangiers Casino, 7 Reels, Winward Casino and Thebes Casino.
