He was also the leading performer for Australia which earned him international recognition, something he had only dreamt of over the years.
Reflecting on his recent achievement, Harrison said "There are always improvements to be made, but I managed to put in a good showing on all 4 routes at this event, which is something I'm really proud of."
While Harrison did not return home with a medal in hand, he has imparted his followers and the wider student community with the important lesson of being one's own competition.
Despite Harrison's recent success, his journey to the international stage must not be ignored.
The 24-year-old first fell in love with the sport on a casual rock climbing outing with his father. From that moment on, sport climbing became an integral part of Harrison's life. Over the past few years, he has faced major losses but his future aspiration to continue "climbing as long and as much as possible" keeps him going despite adversities.
Even though Harrison spends most of his time training in Melbourne's climbing gyms, he also makes time for his education, career and interests. Currently majoring in French Studies, Harrison juggles part-time work and extracurricular activities like music and video games. He finds the challenge personally rewarding, “I like it when I have a lot to do and I am forced to structure myself well. I always enjoy doing new things and being busy", he shared with FISU.
