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.

I started mountain-bike riding two years ago, which is much better than riding a stationary bike in the gym. Mountain biking is a total body workout.

I get my drive and determination from just winning and playing tennis. I know if I don't work, I won't get rewarded. It was a life long dream to win a Grand Slam so when I was able to do that it felt so good and I wanted to do it again. It's not that hard to stay motivated.

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.

In tennis it's easy to get greedy - and one Grand Slam doesn't feel enough any more.

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.

Daniel, my big brother, is eight years older. I'm lucky he didn't mind hanging out with his little sister and my younger brother.
