Wagering industry in spotlight, Chris Waller on building success and a new record looms as Slipper winner sells

This week, wagering reform takes centre stage as a bruising Senate inquiry exposes the political vulnerabilities of both bookmakers and racing, the Coalition signals it wants tougher restrictions on wagering advertising and inducements, and prediction markets emerge as a new regulatory challenge. We also hear from champion trainer Chris Waller following a record-breaking season, discussing scale, innovation, racing politics and why he believes technology can improve confidence in the industry. In breeding and bloodstock, a Golden Slipper winner heads towards a potentially record-breaking sale, Snitzel signs off with one final premiership, and we examine some of the sire categories that often go unnoticed.
