His passion almost came to a halt at the death of his younger brother Someh but he managed to find a way to channel his passion into his brother's legacy.
"This year's competition was so special, as it was Someh's birthday on May 20 so I went up there and did it for him.
"I certainly felt a bit of pressure but just wanted to gift these trophies to him and I was super stoked that I was able to."
As well as Someh, Mr Oli's mentor Ray Astwood, who helped him achieve his national certificate, was also in the back of the barber's mind.
"He was my assessor and helped me through about 80 per cent of my certificate and unfortunately he passed away recently. I wore a T-shirt in honour of him and was happy I could make him proud."
The pair became close last year and last weekend Mr Oli met Mr Astwood's daughter and wife.
"It was really special and made the competition this year with my brother and Ray really important to me."
Because Mr Oli achieved his certificate he is able to enter the masters section of the competition next year, providing him with another challenge.
He said this was something he never expected considering he started clipping people's hair in a changing room.
"I will be up against some of the top barbers and it's pretty amazing really as I basically learnt my passion through my mistakes with trial and error, so this is just a bonus."
Barbering is already ingrained in the family and his two sons, Someh and Jesiah, were the two youngest models at the competition.
"They love it and my wife is also right behind me so it's a real family thing."
Mr Oli's former business partner and some family friends also went up and supported the barbering family.
"I just heard a cheer and when I turned around I couldn't believe it. They gave me that extra bit of energy and boost of confidence, it was amazing."
