RSPCA Victoria has released an audit of the publicly available jumps racing data, finding serious animal welfare concerns, inconsistent data, and a lack of transparency.
RSPCA Victoria Policy and Advocacy Manager, Mhairi Roberts, said the report painted a very concerning picture of jumps racing.
"In defending its safety record, the public has been asked by jumps racing supporters to look beyond the last season and instead consider the long-term jumps racing data," Ms Roberts said.
"What we found, however, was a systematic failure in animal welfare, significant gaps in data, poorly reported information, inconsistencies, and a lack of accountability and independent auditing.
"Our report found one in every 24 horses died in a jumps race this season, and one in every 10 horse starts resulted in an injury.
