Bernborough was foaled at Rosalie Plains near the township of Oakey in the Darling Downs in Queensland.

[1] He came to prominence racing at Toowoomba's Clifford Park when ridden to his first six wins by Les Watterson.

Challenging for the lead just after entering the home straight, he suffered torn sesamoid ligaments and had to be pulled up.

After recovering from his injuries, Bernborough was sold in 1946 for a record £93,000[5] to movie producer Louis B. Mayer for stud duties in the USA, where he went on to moderate success as a stallion at Spendthrift Farm in Lexington, Kentucky.

He is commemorated in the township of Oakey with a life-size bronze statue located outside the Jondaryan Council chambers.
