Registered to play soccer in Australia and an adult? You better not have a punt on an A-League game then, because it breaches the terms of your registration and you can be fined for it.

That was the message from Football Federation Australia on Monday, the body revealing it had issued a registered player in NSW with a suspended fine of $1,000 for placing bets on several A-League matches.

The player is understood not to be involved in the A-League itself.

The activity was reported to FFA by wagering monitoring service Sportradar and while the fine was wholly suspended, that was subject to the participant ceasing their wagering activity.

While there are a large number of adult registered soccer players in Australia, it is thought that the ruling is not particularly well known.
