Mark Taylor, Michael Slater, Mike Hussey and Geoff Lawson say they would be very surprised if spot-fixing claims about an Ashes Test are true.
Prominent former Test players have reacted with disbelief and doubt after a British newspaper levelled fixing allegations at the third Ashes game and Big Bash League.
The International Cricket Council continues to investigate claims by The Sun that revolve around purportedly undercover video of bookmakers offering to sell details of rigged periods of play.
ICC head of anti-corruption Alex Marshall briefed Cricket Australia chief executive James Sutherland in a phone hook-up on Thursday morning, and Marshall indicated there was no evidence to support suspicions of fixing.
Sutherland also said he was unaware of any attempt to fix any aspect of a BBL game.
Former Australia captain Mark Taylor described the report as "nasty stuff".
"James (Sutherland) handled it very well, saying we're taking this very seriously, as Cricket Australia and the ECB should," he told the Nine Network.
"But as James also said there is no evidence ... (and) the players are educated on a six-monthly basis on this sort of thing."
Former Australia opener Michael Slater, speaking alongside Taylor, said he would be "extremely surprised if any player was even tempted, let alone involved".
"Illegal bookmaking goes on and there's an exorbitant amount of money that gets involved in every game that is played," Slater said.
"(But) the less vulnerable players are those who get well paid like the England and Australia players.
"It has to be investigated. It's awful we're talking about it."
Former Australia batsman Mike Hussey, speaking on Fox Sports before play started in Perth on Thursday, echoed Slater's point about Australia's Test stars being so well paid there was no reason they would be tempted.
"Australians haven't really been targeted too much in the past. Hopefully that's the case now. I'd say pretty surely I don't think any of the Aussies are involved," Hussey said, noting he was never approached by an intermediary or fixer in either his international or domestic career.
"I'd very surprised if it's true ... I'd want to see some pretty hard evidence to believe something like this is happening."
Former Australia paceman Geoff Lawson, who is an assistant coach at BBL club Sydney Sixers and formerly a mentor of Pakistan's national team, labelled the claims in the video "preposterous stuff".
"It looks like he knew he was giving a TV interview. That wasn't a quiet conversation. That was somebody asking a very direct question," Lawson told Fox Sports.
"To think you could fix a total of different overs and final totals, I just think, is absolutely ridiculous.
"Most of that stuff I just thought was un-doable."
