Gaming regulators in the Australian state of New South Wales have launched a probe into Tatts Group’s campaign against online lottery betting operator Lottoland.

On Thursday, the Australian reported that Liquor & Gaming NSW had sent Lottoland a letter indicating that it was conducting an initial assessment of the company’s complaint that rival Tatts may have violated its licensing obligations by engaging in a A$5m “misinformation” campaign designed to turn the public, government and lottery newsagents against Lottoland.

Last September, Tatts teamed with the Australian Lottery and Newsagents Association (ALNA) on a Lottoland’s Gotta Go campaign intended to combat “fake lotto betting.” Lottoland doesn’t actually operate a lottery but instead offers players the opportunity to wager on lottery results, including international lotteries unavailable to Aussie players.

The campaign led Lottoland’s regulator, the Northern Territory Racing Commission, to prohibit the company from offering wagers on domestic lotteries. The federal government subsequently introduced legislation to ban betting on lottery or keno results, a scenario Lottoland has vowed to challenge in court.
