Training champions

By 1879, Foley had managed two Sydney hotels; first the United Service Hotel and then the White Horse. One of his responsibilities was tending bar at his hotels, though unlike many of his fellow boxers, he was a tetotaler by most accounts.^[12] After his victory over Hicken, Foley opened a boxing academy at his White Horse Hotel on George Street, though he likely held matches there earlier.^[2] Former English champion Jem Mace, who trained Foley for his championship bout with Hicken, helped open the school and continued as an instructor. At his gym at the White Horse, Foley taught, trained and guided the careers of the great boxers Young Griffo, Bob Fitzsimmons, Paddy Slavin, and Peter Jackson as well as the lesser known Dan Creedon and George Dawson. He was known worldwide for the quality of his boxing training, and acted as a promoter as well at times, helping to mold the career of his most gifted student Bob Fitzsimmons, who would become a champion in three weight classes.^[3]

Foley's greatest contribution to boxing was as an advocate for the modern Marquess of Queensberry Rules, which revolutionized Australian boxing by allowing finesse, speed, and defensive technique to replace much of the brutality more common with the former London Prize Ring Rules. He helped introduce Queensberry Rules at his boxing academy and in the fights held there at his Ironpot Stadium in the back of the White Horse hotel, and he incorporated the scientific, straight-punching methods he learned during his own brilliant career into the techniques he taught his students.^[8]

Australian heavyweight championship

Will Miller

At the advanced age of 39, Foley came out of boxing retirement to fight a gloved battle using the modern Marquess of Queensberry Rules against "Professor" William Miller in Sydney, New South Wales on 28 May 1883 for the championship of Australia. Due to Miller's weight of around 190, the bout was a heavyweight championship. Unofficially declared a draw, the forty round bout and the £500 purse were given to Miller on the next day when Foley conceded he had lost the fight. Miller was a considerably larger and more muscular man, with nearly a forty pound advantage in weight to Foley's light middleweight class of around 158 pounds. The contest lasted three hours and would have been called far earlier if held today, as Foley took a great deal of punishment. Though he had a lead in the first hour, the tide turned and Miller's strong and constant left to Foley's face began to take its toll. In the 37th and 40th rounds, a right by Miller knocked Foley to the mat. Around the 40th round, spectators climbed into the ring, and the police were forced to stop the fight, with the referee postponing the ruling or calling a temporary draw til the following day.^[13][1]

Bob Fitzsimmons

In 1884, Foley fought exhibitions to large crowds in Melbourne and Sydney with several of his top rated former opponents including both Miller and Hicken and strongly preferred to use gloves. Continuing a year of exhibitions, on 12 December 1885, he fought a four round no decision bout, which might be considered an exhibition, against the incomparable English champion Bob Fitzsimmons in Sydney. In his career, Foley acted as both a discoverer of Fitzsimmons' enormous talent, and as his boxing instructor from his earliest days in the ring.^[14] He fought an exhibition with another of his gifted students, Black boxer Peter Jackson, a future Australian heavyweight champion, in Sydney in May 1885. He continued to exclusively fight exhibitions and no decision bouts in 1886, but against somewhat less famous and accomplished opponents.^[1][15] On 30 July 1837 in Sydney, he fought a three round exhibition with his student Mick Dooley, a future Australian heavyweight champion.^[1]

Flush with earnings from his lucrative year of exhibitions he married his second wife Mary Hoins on 12 November 1887 in Randwick.^[3]

Foley fought two very short exhibitions with the first black American world heavyweight champion Jack Johnson in 1907-8 in Sydney. The first was a three round exhibition at Queen's Hall, and the second was a four round charity bout at Manley Skating Rink.^[16] Still a contemporary figure in some ways, Johnson was posthumously pardoned in 2018 by President Donald Trump for his 1912 Mann Act arrest.^[1] In one of his last known exhibitions on 2 May 1910, Foley sparred with onetime world and Australian heavyweight champion, American Tommy Burns in Sydney.

The former middleweight champion also first appeared in October 1880 at Queens Theatre in Sydney in a production of As You Like It, as the character Charles, the wrestler. The touring American actress Louise Pomeroy played the character of "Rosalind".^[17] He briefly attempted to work as a theatre manager, and later appeared in several additional performances as Charles in Sydney in 1882 and at the Royal Standard Theatre from 1886–87.^[18][19]
