George Kambosos Jr. was born on June 14, 1993, in Sydney, Australia. His paternal grandparents hail from Sparta, Laconia, and he proudly carries their heritage. As a child, Kambosos initially played junior rugby league for the Gymea Gorillas. However, he faced bullying due to being obese. To improve his fitness, his father enrolled him in boxing classes at the age of 11, and Kambosos quickly shed the excess weight.
Kambosos made his professional boxing debut in May 2013 at the age of 19. In his debut match, he faced Filipino fighter Jayson Mac Gura and secured victory via a second-round technical knockout. Kambosos also captured the WBA Oceania title in December 2016 by defeating world number nine Brandon Ogilvie. He continued to rise through the ranks, facing opponents like Qamil Balla (whom he defeated by unanimous decision) and Krai Setthaphon (whom he knocked out in the ninth round).
Kambosos’ last fight was against Maxi Hughes on July 22, 2023, where he returned to the winners' column with a majority decision victory over Maxi Hughes in Oklahoma. Despite not being at his best, Kambosos managed to secure the win, improving his record to 21-2. The fight saw both fighters landing shots, with Hughes appearing busier, but the judges' scorecards favored Kambosos. Kambosos acknowledged his need to be more aggressive but expressed eagerness to pursue world title contention again.
