Former high-profile racing steward Ray Murrihy has warned match-fixing allegations in Australian sport will not be confined to rugby league.

Following his decision to step down as a steward after a 46-year career in horse racing, Murrihy worked with NRL club Manly when the Sea Eagles were first linked to match-fixing investigations.

And while he believes Manly now have the proper safeguards in place, he says any club or sport can’t be 100 per cent certain they will be immune from further scrutiny.

“Those allegations certainly won’t be the last of them,” Murrihy told AAP.

“They’ll be raised from time to time across a whole range of sporting codes.

“We’d be foolish if we didn’t think from time to time these matters won’t be raised.”

Murrihy recommended Manly make changes to governance, dressing room access and the players’ codes of conduct.

“Manly were already compliant with their requirements,” he said.

“But they now have a set of governances now that provide far superior safeguards to what they had only a few months ago.”

That has prompted calls for his return to administer league-wide issues in the wake of NSW Police establishing a strike force to investigate games involving Manly.

However Murrihy is not interested in forcing rules on organisations, but suggests all sports need to continually update their protocols if they want to minimise gambling issues.

“It’s not for me to say that every other sporting organisation should followed suit,” he said.

“If I reflect on racing we don’t apply the same standards we did five years ago or 10 years ago.

“It’s an ongoing battle.

“From there on there’s no guarantees.”
