The enthusiastic youngster was driving trackwork by age 11.
And if he wasn’t assisting with the horses, Clarke was regularly playing Aussie Rules Football, basketball and swimming.
But halfway through school in Year 8 as a 14-year-old, Clarke suffered back pain during a game of footy.
Originally, the cause went undetected after a trip to the local hospital, but a follow-up MRI scan located the issue.
Clarke was diagnosed with Stage 4 Non-Hodgkin’s lymphoma (NHL), a type of cancer affecting the lymphatic system - a part of the immune system - where lymphocytes (white blood cells) grow uncontrollably to form tumors.
Beyond shocked, Clarke and the family naturally buckled down and underwent immediate treatment at the Melbourne Royal Children’s Hospital before a stint at the Ronald McDonald house.
At the time, Clarke was blissfully unaware of the seriousness of the situation he faced.
“Obviously I didn’t know at the time, but the doctors weren’t confident that I could be cured as Stage 4 is fairly heavy and it was everywhere in my body,” he said.
“Apparently they gave me a 30 per cent chance of surviving it, but they weren’t going to tell a 14-year-old that.”
Following six months of treatment, Clarke received excellent news.
“I was on the road to recovery and in remission, it was a huge relief and more so for my parents, it turned our world upside down,” he said.
“Maybe it was naivety but all I could think about was the horses and working with them and driving them again.”
