Racing and Wagering WA stewards have found thoroughbred racing to be clean, despite innuendo on corruption within the industry.
Claims have been made on racing discussion websites and within the industry over the past year of a Sydney-based betting syndicate having WA jockeys on its payroll to fix races at Ascot and Belmont Park.
The rumours of race fixing have spread to country races held at Albany and Esperance.
The allegations targeted horses which raced outside of their usual pattern - in particular leaders or on-pace runners - in races where big plunges have been successful.
Racing integrity general manager Denis Borovica said yesterday's release of findings on an Australia-wide investigation of betting activities on WA racing over 2012 was not instigated by industry rumours or the investigation into the alleged murder of racing figure Stephen Cookson.
"This is part of our usual routine examination," he said.
"I am aware of websites and innuendo from within the racing industry and from the police investigation of Mr Cookson.
"This investigation has no association with any of it."
During the inquiry, chief investigator Phil O'Reilly questioned big punters known to bet on local races at WA TAB agencies.
Stewards also spoke to interstate TAB agencies, corporate bookmakers and betting exchanges on the operations of certain WA punters.
They targeted accounts where there was strong betting activity on horses to verify if there were any links.
Analysis of the data and post-race reviews found there was no significant bias or statistically significant correlation with any rider's mounts being backed or laid.
There also was no significant bias or statistically significant correlation with any particular trainer and the betting patterns of the people involved were consistent with their wagering patterns in other States.
Stewards found the bets were placed as a result of a sophisticated and professional system being used nationally and, in some cases, across codes.
On one account they found there was a slight bias to backing horses who settled on pace, however it did not correlate to a particular jockey or stable.
One punter had 10,000 bets on WA races in 2012 with a single wagering operator.
They were examined to check for any relationships or associations with particular stables or jockeys.
No major bias was detected by the inquiry.
The investigation saw stewards target a smaller number of races for detailed examination.
The finding was that the punter had spread his or her liability by supporting other runners with a certain operator or other operators to varying degrees.
"The completeness of the extensive wagering records and data available to the RWWA stewards indicates there has been in certain instances complete misinformation and unfounded speculation within the industry in relation to both wagering patterns and the identity of their source," Borovica said.
RWWA has a new tool to use in its integrity with it now able to access data from the Federal Attorney-General's Department.
