Great concept. Sports punters love a 50/50 chance. All states could have a series of provincial run offs running into city run offs over a two to four week period.Then have national finals.
Surely state greyhound boards would buy in on the racing welfare aspect.
Grab Tabcorp as a sponser,involve media and marketing power and bingo,the dogs have a new product that brings fresh interest, such as the horses have done with the Everest.
Just have to get everyone on board.
