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.

You hear a few people saying that, you know, maybe some of the past male players like to watch me play or whatever else, just because I play a bit differently and maybe they can relate to it a bit more with a bigger forehand rather than a backhand, good serve and whatnot.

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.

It is never too late to get into tennis! While I started playing at the age of 8 when my parents gave me a tennis racquet for Christmas, tennis is a lifelong sport that can be enjoyed by people of almost any age. It's also something you never forget once you learn.

People think that there is so much money in tennis, but the reality is unless you're ranked in about the top 50 you don't earn much at all. It is hard to support yourself travelling the world, to be away from home most of the year and to pay for a coach to help you become a better player.

Receiving the Newcombe Medal for a third year in a row is an amazing honour. The Newcombe Medal is a great occasion for the Australian tennis community to come together and celebrate our sport, recognise people's achievements and contributions to Australian tennis.

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.
