Fairfax Media says organised crime experts have identified A-League football and Big Bash cricket as likely targets of Asian crime cartels.
Victorian Deputy Commissioner Graham Ashton told Fairfax that match fixing was imminent in Australia.
"This thing is coming down the highway and we have to be prepared," he said.
He warned sportsmen against associating with underworld figures who could try to blackmail them.
"It can begin with one small incident - cocaine at a party or a prostitute - and then they are on the hook," Mr Ashton said.
"It follows an established pattern: attract, compromise and then infiltrate."
Fairfax said there had been a massive increase in Asian betting on Australian sporting events, with up to $40 million held offshore on one A-League game.
The AFL is briefing all players on the dangers of associating with criminals and the risks of being groomed by illegal betting cartels.
