Melbourne Victory A-League coach Ange Postecoglou has expressed his disbelief over the $2 million match-fixing scandal involving a Victorian soccer club.

Postecoglou is demanding appropriate penalties for those involved as a deterrent to others.

"Like most people there's a fair sense of disbelief at what happened," Postecoglou told a media conference on Tuesday.

"FFA (Football Federation Australia) and all clubs are looking at all their governance issues.

"It does heighten your sense of responsibility and understanding that we could all be exposed to it.

"I'm sure every sporting club in this country will be sitting down today or in the next few days and making sure all their processes and governance are correct and fit and proper.

"We try to make sure we're vigilant.

"That's the biggest thing that alerts you to (the fact) you can't be complacent, because it's pretty much on our doorstep.

"I'd suggest 99 per cent of the community had no idea it was going on."

Malaysian national Segaran "Gerry" Gsubramaniam allegedly received instructions from Hungary and Malaysia on what the results of Southern Stars soccer matches should be, the Melbourne Magistrates' Court heard on Monday.

One of those instructions was for the Victorian Premier League team to lose a match 4-0, the court was told.

Gsubramaniam is accused of passing the information on to the team's coach and some players.

Southern Stars secretary Tony Kiranci says he and the club are shocked by the match-fixing allegations and they're fully co-operating with authorities.

"You can't assume these things won't crop up," Postecoglou warned.

"Corruption and this kind of thing in sport has been going on for over a hundred years.

"The biggest thing you get out of it is hopefully the punishment fits the crime. That would be a bigger deterrent than any other process.

"I've been pleased with the way the police, the government and the governing body FFA have dealt with this matter so far, the seriousness of this matter.

"I don't think it taints our sport.

"The fact their target was a lower-tier sport where maybe the processes aren't as diligent in the short term shows that we must be doing something right at our level."
