After 200 years or so, Racing Victoria has given in to the hysterics and banned all forms of horse race jumping. There were 8 horses killed last year in falls which was the catalyst.
The real problem was caused by racing Victoria itself. Hurdles went from 6 foot tall where horses had to actually jump, speed really wasnt an issue, to a mad half sprint where hurdles were 3 foot tall with the top foot just brush. So horses lose their footing and break their necks or legs.
Its just another part of Austayan kulcha down the gurgler.
