Australian Federal Sport Minister Kate Lundy says getting consistent laws across the country remains the key to fighting match-fixing.
Lundy on Wednesday announced the establishment of a new national integrity of sport unit (NISU), the latest step in a policy agreed on last year with all state and territory governments.
The unit will not have any investigative or enforcement powers, but will work with governments, sporting bodies, betting and law enforcement agencies to facilitate a coordinated approach.
But the minister said the lack of specific match-fixing laws in most states meant laying criminal charges remained difficult.
"Part of the challenge now is for charges to be laid under criminal law. It's usually done under a fraud case, so it's quite difficult to prove," she told reporters at the announcement at Netball Australia's head office in Melbourne.
"By having specific state jurisdictions put in place - criminal sanctions relating specifically to match-fixing and described behaviours - it makes it easier to bring charges and test allegations for people who are accused of such things."
While all state and territory governments signed off on the policy framework in June last year, so far only Victoria and NSW have specific legislation.
