From the backyard to the Olympics, this star equestrian has had a little help from her friends.

Partnerships in life are so important, whether they are with family, friends, colleagues or even animals. Partnerships are how my success has been created.

In 2011, I enjoyed my most successful year to date. I signed a multi-year contract with Gucci and Jaeger-LeCoulture and I won the ''formula one of equestrian''- the Global Champions Tour. My success has been dependent on partnerships.

I grew up in Sydney. My family did not have horses but our neighbours did. I spent all my spare time with their horses. At the age of eight, I dreamt of going to the Olympics with a chestnut horse and a blue riding jacket.

My neighbours owned an unbroken pony called Bo Jangles. One day, with no riding experience, I tied a rope to his halter and decided to get on him. For some reason he allowed it. I rode him regularly around my house and this was my first partnership with a horse.

Pony club followed and I had some competitive success. But from around age 15 I had horses that were not so good and I lost my confidence. I questioned my riding, but I could not bear to give it up.

My family bought some new horses and I found another trainer, as my first one had given up on me. I began to win, going on to win the Australian Young Rider Championships. I went from strength to strength and in my early 20s decided to test myself against the rest of the world. With the help of my supportive parents, I took a horse called Mr Dundee to Europe. I believe that everybody has one chance in life and this was mine.

It was difficult on my own but I learned so much and enjoyed the challenge. Eventually I moved to Holland and started my own business. In 2002, I rode at the world championships. In the same year I met Jan Tops, to whom I am now married. He has been the basis of my success. I would not be where I am today without him.

Things were tough at times and at one point I started to lose interest in riding. Jan then asked me if I was interested in investing in a horse called Pialotta.

Pialotta was a 14-year-old mare that had won grand prix classes with other riders. I didn't know if I was good enough to ride this horse but with the aim of finishing in the top 25 at the 2006 world championships, we ended up fourth.

I was the first Australian to achieve this result. I had an amazing partnership with Pialotta and this was when my career began to evolve.

In 2007 Jan, businessman Cees Van Opstal and I invested in a new horse called Itot du Chateau. Bonding with horses take time. Yet with Itot I felt this the first moment I jumped him.

I have enjoyed great success with Itot, including riding at the Olympic Games in 2008. So there I was on a chestnut, wearing a blue riding jacket!

I compete 48 weekends a year all over the world. I don't have much free time but I love what I do. I would prefer to live near my family but sport is full of sacrifices and if you are not prepared for this then you are not prepared to win.

There are reasons why things happen - bad horses, disappointments, a change of trainer. It is so important to find the right partnerships in life and that is why I am where I am today.
