@smithy. The import fee will provide around 3/4 of the funds needed. Each horse only pays once.
The stats show that NZ horses win more prizemoney than Aus horses on average so even after paying the $5000 they will still be infront.
Allmost 20% of Aus prizemoney is won by NZ horses. This is fine if that money goes to Aus owners and is reinvested in Aus Harness racing, but I'm sure a large part of it goes to Nz and doesn't help our industry much at all.
Most of the people at your riot will be nz breeders and import agents. I'm sure those police from the above video will keep you all safe.
