Retired Australian cricketer Dirk Nannes suspects he has played in games which had been fixed.
Nannes, a journeyman who played in a host of Twenty20 competitions around the world, said his concerns mostly centred on the Bangladesh Premier League.
He says spot-fixing was widely suspected in the Bangladeshi competition.
"The (International Cricket Council) security guys knew it," Nannes told ABC radio on Friday.

"The guys on the ground knew it; everybody knew it. What do you do as a player?

"The ICC guys, unless you've got the smoking gun, they've got no investigatory powers to confiscate phones and stuff all over the world - you can't go round doing that unless you're the police."
Nannes, who played 17 T20 internationals for Australia, said the Bangladesh league "was the interesting one."
"There were (team) owners who would come along," he said of his stint with Sylhet Royals in Bangladesh.
"The owners weren't allowed on the ground but there would be a team manager going to the owner and saying 'what are we doing next?', then going to the coach.
"The security guys were saying enough was enough but it just kept going on.
"The owners were sitting there on the phone. The owners were demanding that they be in constant touch with the coach because that's why they bought the team."
Betting spotters were noticeable in the crowd, Nannes said.
"They would have a microphone in the cuff of their shirt and 10 mobile phones around their waist," he said.
"Any time something happened, they would lift their sleeve and speak into the microphone.
"Security couldn't do anything except kick them out. Actually in Bangladesh, they couldn't even do that."
Nannes had no suspicion of fixing in Australian cricket.
"My opinion, everyone I played with in Australia has always gone 100 per cent to win the game," he said.
