A new research article has cast fresh light on one of Australia’s most serious race-fixing cases, detailing how Victorian racing investigators used betting-pattern analysis to expose a scheme involving two jockeys and a professional punter.
The revelations, published in the IFHA Council on Anti-Illegal Betting & Related Crime by Racing Victoria’s Brent Fisher, show how the punter exploited insider information to manipulate betting markets between April and August 2022, prompting some of the heaviest sanctions seen in Australian racing.
Racing Victoria (RV) launched its probe in August 2022 after its Betting Intelligence Unit detected abnormal activity on Betfair Australia.
Investigators soon established that the punter controlled 16 betting accounts, including nine ‘bowler’ accounts registered under other names to circumvent wagering limits.
Although the punter’s betting history showed only modest profits over the previous 15 months, his behavior changed dramatically from April 2022 onward. The better began picking horses ridden by two jockeys with an extraordinary level of success.
Over a four-month period, the individual placed 135 lay bets against their mounts, and 133 of them were successful — a rate RV investigators said was far beyond statistical plausibility.
The size of bets also increased substantially. The individual was wagering an average of AU$29,449 ($19,136) per lay bet on the jockeys’ rides, compared with less than AU$3,000 ($1,948) on other riders. By late August, 83 percent of all the punter’s betting outlay was concentrated on races involving the two jockeys, generating profits totaling AU$363,894 ($236,306).
The success in head-to-head markets involving the jockeys reached 87 percent, a probability of only 0.74 percent occurring by chance, according to RV.
Interviews reveal deception

RV interviewed the punter in August 2022, with investigators reporting that he gave vague answers and concealed key information about his relationship with the jockeys and about the bowler accounts.
After this initial interview, he abruptly stopped wagering against the riders and quickly began losing money, finishing the period from September to December 2022 down AU$23,879 ($15,508).
A second interview in January 2023 followed the seizure of 1.7 terabytes of mobile-phone data. In that interview, he disclosed additional third-party accounts and claimed that a middleman — identified as “Person A” — acted as an intermediary for one of the jockeys.
The breakthrough came in June 2024, when RV investigators secured phone records tied to two SIM cards. On the punter’s device, they found a saved Signal message that referred directly to Race 3 at Swan Hill on August 7th, 2022: “Race 3 lay the 1 for 70/80. Have 10K on mine to beat his H to H.”
RV said these instructions aligned precisely with the punter’s recorded wagers. He risked nearly AU$100,000 ($64,935) laying the horse ridden by the second jockey and placed AU$8,734 ($5,669) on a head-to-head bet backing the other jockey to defeat him. The targeted horse finished 11th, beaten by more than 13 lengths.
RV charged both jockeys and the professional punter with multiple breaches of the Australian Rules of Racing, and all three pleaded guilty.
One jockey received a 13-year-and-six-month disqualification for corruption, dishonesty and misconduct. The second jockey was disqualified for 10 years for corruption, conduct detrimental to racing and failing to provide required information. The punter was warned off for 10 years.
RV said the prosecution illustrated the critical value of real-time wagering surveillance, advanced digital-forensic capabilities and strong cooperation with betting operators.
The evidence brief submitted to the Victoria Racing Tribunal exceeded 3,800 pages and was supported by expert testimony in betting analysis, mobile-phone forensics and voice-recognition technology.
According to the report, the case demonstrates how modern monitoring tools can penetrate encrypted messaging, burner-phone usage, and digital obfuscation.
Racing authorities warn that this type of internal manipulation remains one of the gravest threats to the sport’s integrity and that sustained investment in investigative capacity is essential to maintaining public confidence.
