He began playing junior rugby league for the Gymea Gorillas at a young age and was often bullied as a child for being overweight so his father enrolled him in boxing classes at 11 years of age to improve his fitness. Kambosos quickly dropped the excess weight and was placed in the Cronulla Sharks development squad where he was coached by Ricky Stuart but found himself at a crossroad as a teenager when he was forced to choose between boxing and rugby league. He elected to pursue the boxing pathway and began his fighting career by amassing 85 wins in 100 amateur fights before turning professional.Kambosos made his professional boxing debut in May 2013, at the age of 19, when he faced Filipino fighter Jayson Mac Gura and was victorious via a second round technical knockout.
