According to the Herald Sun, PokerCricket.com was ruled by the commission to have broken the state laws as it did not have a licence to operate in Victoria.
''It is illegal to offer or advertise in Victoria the playing of interactive gambling games,'' executive commissioner Peter Cohen was quoted by the newspaper as saying.
''Gambling is a strictly regulated business and we would expect all people to comply with legislation, irrespective of their profile,'' he added.
However, Warne escaped punishment by the regulator because his management had removed the UK-based site from the internet.
Meanwhile, anti-gambling campaigners accused Warne - who said on the site that poker players should not be scared of losing - of cashing in on vulnerable people.
