Match fixing - it is all anyone has been talking about since the start of the Australian Open. As soon as the BBC in Britain said it was going to run a documentary on corruption in tennis, everybody has been asking me, and all the other players, what we think about it and what we know.
And that's the thing - we don't know that much. But I want to know. I haven't personally played a match where I've thought something was up. And I haven't really watched a live match and thought "this is being fixed". 
I would actually like to know if there was any match I was involved in that had had irregular betting patterns around it or anything like that.
If there is corruption in sport, you want to hear about it. I read the story on the website BuzzFeed and some of the stuff I wasn't aware of, like I didn't know so many matches had been flagged as suspicious with the betting companies.
As a player, you just want to be made aware of everything that's going on. I think we deserve to know everything that's out there. Some of it will be true; some of it might not be true. But I think sports could in general be much, much more transparent.
The BBC story made lots of allegations, but it didn't name any names and that's a hard one. As a player I would really like to know.
I would like to know the names and the matches that are being looked at so that I could watch the matches myself and make up my own mind about them. But obviously, unless you have concrete proof, which is very hard to get, you cannot just start naming players. Legally, you can't do that.
Obviously, the story is not good for the image of the sport, but from my point of view as a player, I don't think everyone is being tarred with the same brush. It's not like everyone thinks we are all cheating. I feel comfortable with myself so that's not something I'm worried about.
I'm more pro 'let's get all the information out there, get all of the evidence out there' and as a player I want to know. I just want to know everything that's going on and I think a lot of the players do. If you're innocent then you want to find out about the players who have been doing stuff, if there are any, and we want them to be prosecuted.
I don't care whether the tennis authorities are seen to be doing enough; I care whether they are doing enough. And I don't know if they are because I have no idea how much money is invested in the tennis integrity unit. So much money is gambled in tennis during a year - it's a huge industry.   Maybe more could be done to prevent corruption but I have no idea how much money tennis spends in comparison to other sports.
I do think it's important that from a younger age players are better educated and are made more aware what goes on out there and what they should do in those situations. How making a bad decision can affect your career, can affect the whole sport. Across all sports, I don't think that that's done particularly well. I think you should be learning about those things from 15, 16, 17 years old and being warned about it.
When you come on the tour, players need to be educated and have the right people to support them in those situations, I think.
What I do think, though, is that it is a little bit hypocritical that tournaments are allowed to be sponsored by betting companies. I believe that the players are not allowed to be sponsored by betting companies but then the tournaments are. I think it's a bit strange.
Some people confuse gambling with corruption but that is wrong. People in Australia have always liked a bet but look at your sports stars - you could not find a player straighter or more honest than Lleyton Hewitt, for example.
A lot of people can gamble responsibly but some people cheat and take things too far. And not just in tennis but in all sports. There's been problems in cricket, cycling, athletics and football - and it's at the highest level. That stuff happens and when it does you want to make sure the people involved are prosecuted and are banned.
