The New South Wales (NSW) gaming watchdog has prosecuted four sports betting companies as it ramps up its crackdown on ads that seduce local residents to gamble.

The Office of Liquor Gaming and Racing (OLGR) has indicted local operators Tabcorp Holdings Ltd., Hillside (Australia New Media) Pty Limited, CrownBet Pty. Ltd and Betchoice ​Corp. Pty Ltd.

Tabcorp spokesman told The Sydney Morning Herald that it would be defending the charge. CrownBet, Hillside (trading under Bet365 Group), and Betchoice​ (trading as Unibet) declined to comment.

OLGR is keeping a close watch on gambling related ads across all mediums that breach NSW’s Racing Administration Regulation 2012, “to ensure compliance and reduce the risk of regulatory action.”
