<p>Hall of Fame trainer Chris Waller has written to Racing Minister David Harris clarifying his position about a controversial industry letter raising concerns about Racing NSW while hinting at criticism of its chief executive Peter V'landys.</p> <p>Waller wrote an email to the racing minister effectively distancing himself from the letter sent to the racing minister on April 14 by owner-breeder Julia Ritchie from the "Save Rosehill" group which called for an independent review of the Thoroughbred Racing Act due to an "erosion of trust in the governance structures currently in place".</p> <p>The names of 27 prominent racing identities - including Waller - were on the letter but Sydney's premier trainer said in the email: "I wish to make it absolutely clear I did not sign any such letter, nor do I support the sentiment it implies. In fact, my views are quite the opposite.''</p> <p>In Waller's email, he described V'landys as "an extraordinary administrator, arguably the best the sport has seen" after overseeing the remarkable transformation of the NSW racing industry in recent years.</p> <p>"My greatest concern is that any proposed changes could destabilise the current moment and leave Racing NSW vulnerable at a time when all sports are facing significant challenges,'' he wrote.</p> <p>Waller told the minister he did have concerns about the proposal to sell Rosehill racecourse, where he has his stable base, for $5 billion to make way for a new suburb with up to 25,000 homes.</p> <p>"While I understand the potential of this helping alleviate the housing shortage in Sydney, I question whether it will truly result in affordable housing,'' Waller said. "More importantly, I question how a comparable track to Rosehill can be rebuilt without losing its critical metropolitan footprint.''</p> <p>A spokesman for Harris said the "Minister for Gaming and Racing previously committed to commencing a review into the Thoroughbred Racing Act 1196 this year, as the Act had not been reviewed since 2014".</p> <p>"The purpose of the review is to determine whether the Act is still fit for purpose,'' the spokesman said.</p> <p>"We will follow the usual processes in conducting the review. Further information about the review, including its scope and timing, will be made available in due course."</p>
