NSW police say they are investigating allegations of sports match-fixing.
The investigations by the organised crime squad follow intelligence suggesting players have sabotaged matches to benefit crime figures.
Detective Superintendent Scott Cook told News Corp the squad's investigations were just beginning but information suggested there was corruption in a number of sports and at different levels "including professional and second, third and fourth divisions, not just the elite sports".
"Our focus is those events where matches have been changed and outcomes have been changed. That's the biggest corruption of sport," Cook said.
"It's early days for us, but we're looking to develop the intelligence to proceed into prosecutions.
"We're investigating some matters as we speak."
Police believed much of the alleged match-fixing was arranged overseas.
"All the arrangements might be made offshore and just the match is played here, which makes it very difficult for us in terms of prosecution because all the evidence is offshore," Detective Superintendent Cook told News Corp.
"The majority of intelligence concerns offshore betting agencies and groups engaging with organised crime to corrupt matches in Australia."
He said no sport was immune to corruption.
"The intelligence we are getting suggests that most sports have been infiltrated to some degree, but its just a few people, not thousands."
He said match-fixers were looking to prey on susceptible sports people.
"A lot of the information were getting is that players and sports people are being influenced or approached in social settings in order to manipulate them ... that is one example," he said.
"Other examples are when some players who have gambling problems themselves and in some circumstances we have information about players themselves organising a corrupt outcome in order for them to make money."
A spokeswoman for the squad confirmed in a statement on Sunday that they were "aware of some isolated activities which are currently under investigation".
