An industry worth $335 million outside of the wagering is going to cost a little more than $30 million to transition.
The cost of just feeding the dogs normally is $36 million per year. GAP costs $60 per day, per dog, and it usually ends up costing $2500 per dog to have them adopted.
The reason politicians normally stop any closure of country tracks, despite them being a huge financial drain on the sport is that greyhounds pay for the upkeep, infrastructure and wages for the many showgrounds. Look at Dapto Dogs, everything was built by greyhounds, the staff that upkeep that showground are paid for by greyhounds. This allows many other community activities to be heavily subsidised by the Trust.
Those millions have to be replaced by Govt every year, forever.
