When I'm playing my best, like I was at the U.S. Open, I feel on top of the match and able to do exactly what I want. There are other times when you're not in control, but that is tennis and you have momentum changes in every single match.

That $27,000 that a young player will now get just for making the main draw at the Australian Open is huge. It can set them up for a couple of months which at that level you really do need that kind of help. It sounds like a lot of money, but when you're travelling the world trying to make it as a tennis player, it doesn't last long.

Core strength and stability is very important to me. Tennis is all about rotation of the body and my ability to create power. I incorporate a lot of abdominal, back and glute exercises into my gym sessions.

I think all tennis players have to struggle through the early stages of their career. We start off playing tournaments and really just get by. I always had a dream to play in the big tournaments and never have doubted if it was worth it. Having to battle a little early on in my career makes it all the more worthwhile now.

I'm not the first player to have their home Grand Slam and not perform. There have been a few Australians and French players, you name it. It's a tough thing. But it is one of those things. Would I rather have a Grand Slam in my country than not? I would.

I don't really remember the day we lost our home in the floods, but looking back I can understand how devastating it was for my parents. I was only six, so I remember us having to move to Adelaide - but not much of the actual day and night of the flood. We had to start all over again and my parents opened a café.

Tennis is all about mental toughness, and you have to keep your head in the game. I make time to relax away from competition pressures, travel and intense training schedules to make sure I'm looking after myself. Taking time out with family and friends helps to maintain the work-life balance everyone needs.
