John mcmullen fought and lost to ken marshal who was then rep for AUS . BUT
Madigan was stunned to find that to get the chance of a rematch with Ali in Rome, he had to face a stern opponent from outside the ring: The Queensland Boxing and Wrestling Union. The Australian selectors had already chosen a Queenslander, Ken Marshall, to fight in the light-heavyweight division at the Olympics, based on the assumption Madigan was not available and would not be returning home to stake a claim for inclusion in the Rome team. Some Australian boxing officials had other ideas, however, believing Madigan was a distinct gold medal chance and should be convinced to return to Australia. Faced with this prospect, the QBWU took desperate action. As Madigan had been registered as a Queensland-based fighter when he was last in Australia, in 1957, the QBWU felt it had the last say on his eligibility. And it declared Madigan was not only residentially unqualified to represent the country, but that his modelling career – for which he’d used images of himself in boxing garb - had violated his amateur status. Even US sports columnists got in on the act, lampooning the QBWU’s stand as taking the definition of amateurism in sport to a ridiculous degree. Sanity eventually prevailed. Madigan arrived in Sydney in late May and nine days later fought Marshall, on June 6 in Sydney, making mincemeat of him. Afterwards, Madigan expressed his sympathy for Marshall, saying officials had placed the Queensland boxer in a humiliating position. Yet Madigan’s return bout with Ali in Rome had come close to being jettisoned by an overzealous, narrow-minded committee of faceless men.
