Greyhound Racing NSW is urging its members to lobby against the rollout of a ban on online gambling advertising, warning the cuts to revenue would "kill the sport". The federal government is looking at a multi-year plan to phase out online gambling, with several ministers examining recommendations out of a committee report. The report called for a staged ban on gambling advertising across three years, beginning with a ban on online inducements, such as multi-bets, rewards programs and early cashouts. In an email sent to members, Greyhound Racing NSW CEO Robert Macaulay described the plan as government intervention that would cause a 40 per cent reduction in income and a $20 million annual hit to the industry. "This recommendation, if implemented, would have very significant negative impacts on wagering revenues, thus taxes, thus income to the racing codes," Mr Macaulay wrote. The email said the financial losses would be about two thirds of the sports annual prize money in NSW, and would "eat up all our welfare programs, safety and rehoming." The loss to all forms of racing in the state would reach $90 million each year and impact the maintenance of essential welfare and adoption programs, Mr Macaulay wrote, adding the "animal welfare implications alone are huge." He urged members to contact the federal ministers consulting on the report to formally oppose the recommendations, as well as their local state MPs to lobby against any changes to the advertising laws. Email contacts for the ministers for sport, communications and social services were listed in the letter. "It would have devastating and irreversible consequences for our sport, every dog in it, every person in it, every club, every track, and all those towns and villages in NSW where greyhound racing is a local sport," the email read. The report from the Standing Committee on Social Policy and Legal Affairs found current industry regulation is "inadequate to reduce harm". It found there is insufficient regulation of online gambling and restrictions on advertising in Australia, and urged the government do more to prevent problem gambling. Australians spend the most in the world per capita on legal forms of gambling, losing $25 billion every year. Australian Associated Press
