The Australian Open is stepping up its integrity measures following recent match-fixing concerns, and is also removing courtside ads for its betting sponsor.

The tournament will employ two investigative officers on-site who will conduct "random" surveillance of matches for the first time. It also has agreements with bookies requiring them to report any suspicious betting activity, which can be an indication of potential match fixing.

"Although we have no evidence of widespread corruption in Australian tennis, we have recognized that the potential to corrupt is there, and as such we have taken extensive steps to safeguard our sport," Tennis Australia President Steve Healy said.

A year ago, the tournament began with a widely-publicized media report that suggested the sport was insufficiently policing the problem. Spanish police recently arrested 34 people in connection with a match-fixing inquiry at lower-level events, where the majority of suspicious activity appears to happen.

Tennis Australia will also have officers at its other events, including tournaments in Sydney and Brisbane, and will have increased prize money at lower levels to discourage players from getting involved in fixing attempts.

The Australian Open will also not have courtside advertising for online bookie William Hill, though it will remain a sponsor of the event. Speaking to Australian reporters, Healy said that the betting agency agreed with the move.

“We need to put it in perspective,” he said. “The arrangements that were struck with William Hill before this issue had such a high profile, and so we've worked with our partners to address that."

It is the only Grand Slam to have a betting sponsor, though some tour events have similar arrangements.

With at least one low-ranking Australian player having received match-fixing convictions from the courts, Tennis Australia is also conducting an education campaign for younger players.
