Leslie followed in his father's footsteps as a "top notch gentleman jockey" and he rode in amateur races as a young man. He studied to become a solicitor and was admitted in 1894, practicing law in Armidale and Gulgong. In 1897 he was appointed coroner for Gulgong, but his love for horses and horse racing was still a driving force in his life. He resurrected the Gulgong Races in 1899 and acted as handicapper, and was elected as an officer of the Mudgee District Racing Club the same year. The Mudgee Guardian described him as 'a young man with plenty of go'.
Leslie was appointed as a Stipendiary Steward for the A.J.C. (Australian Jockey Club) in 1904, and in order to fulfil this role he sold his Gulgong legal practice. The same year he married Hilda Bowman of Merotherie Station. Leslie devoted himself to the A.J.C. and in 1913 was appointed Keeper of the Stud Book and Registrar of Racehorses. His love of breeding, bloodlines, and racing made him the ideal person for this job, in which he remained until his untimely death in 1928.
