Authorities have confirmed one potentially fixed match, but will not identify the sport. Officials from the local Australian Rules football organisation (AFL), and the Football Federation of Australia (FFA), which runs soccer, have said there are currently no match-fixing investigations underway.
Police would not confirm whether they had any match-fixing investigations underway, adding they would not necessarily notify sporting bodies due to sensitive information, often gained through telephone intercepts.
An FFA spokesman on Friday said they were looking to identify the 2012 soccer match which attracted the $40 million Asian in bets.
"It is understood the FFA is looking into identifying the match relating to this betting plunge but has received no information relating to a breach of integrity in any of its matches," the spokesman said.
Police in the state of Victoria have expressed concerns that the increasingly large bets from Asia have increased the risks of soccer match-fixing in Australia's top flight A-League.
