World No. 2 Andy Murray has labelled the decision to appoint a betting partner at a grand slam as "hypocritical".
The Australian Open became the first grand slam to have a betting agency (William Hill) sponsor the tournament, but Murray is opposed to the historic partnership.
"Yeah, I'm not really pro that, I don't think," the Scot said. "I think it's a little bit hypocritical, really. You know, because I don't believe the players are allowed to be sponsored by betting companies but then the tournaments are. I don't really understand how it all works. I think it's a bit strange." 
Murray's comments came as Australian rising star Thanasi Kokkinakis opened up about being propositioned on Facebook to fix a match. Kokkinakis said he believes corruption exists in all sports, but reports by the European Sports Security Association indicate tennis is open to match-fixing more than any other sport.
In the first nine months of 2015 there were 49 suspicious-activity alerts raised, with only 16 alerts raised throughout the same period for all other sports according the ESSA reports.
"I didn't know that so many matches had been flagged up with the betting companies," Murray said. While Kokkinakis didn't want to detail his experience, he revealed how he was approached on social media.
"Match fixing affects every sport," Kokkinakis said. "Luckily in tennis we have a great program in place, we have the tennis integrity unit and you just report it to them and they get it all sorted. It happened [to me] on Facebook a while ago.
" ... Not really [shocked]. I know it happens in every sport. I'm ready for that sort of stuff. People do it. You just leave the professionals to deal with it."
While names haven't been released in the BBC and Buzzfeed reports, several players have since spoken about approaches made to them, demonstrating how prevalent the issue is in the sport. World No. 1 Novak Djokovic had been offered more than $200,000 to throw a match in St Petersburg in 2006. Kokkinakis wasn't offered anywhere near those figures, and insists he never considered the approach."I have [received offers], not face-to-face, but on social media," he said.
"You read some stuff on your Facebook page, just randoms from nowhere, saying, 'I'll pay you this much money to tank the game', but you try to block it off ... get rid of that stuff and focus on what you need to do ahead. You don't really take it seriously, there's all these randoms around the place."
While not every player is being approached, a lot have to deal with a barrage of abuse on social media from members of the public who have lost money on the matches they play.
"I cop abuse on Twitter for every single match I lose - sometimes even matches I win," Australian John Millman said.
"It's not even the match fixing. The ATP has done a good job setting up this tennis integrity unit and any problems we go through - that's how I deal with it ... I haven't had the approach, but any Twitter abuse or stuff like that, they handle it."
Roger Federer wanted concrete information before speculating over concerns of grand slam champions being involved.
"I would like to hear the name," Federer said. "I would love to hear names. Then at least it's concrete stuff and you can actually debate about it. Was it the player? Was it the support team? Who was it? Was it before? Was it a doubles player, a singles player? Which slam? It's so all over the place. It's nonsense to answer something that is pure speculation.
"Like I said, it's super serious and it's super important to maintain the integrity of our sport. So how high up does it go? The higher it goes, the more surprised I would be, no doubt about it. Not about people being approached, but just people doing it in general."
