Leon Gregory, from South Australia, teamed with David Lean, Graham Gipson and Kevan Gosper to win the silver medal behind the powerful American combination in the 4 x 400 metres relay at Melbourne 1956. This was the first Olympic medal by an Australian men’s athletics relay team. The next was the same medal in the same event by the ‘Silver Bullets’ (John Steffenson, Mark Ormrod, Pat Dwyer, Clinton Hill) at Athens 2004. The Melbourne Olympic Games was the only time Gregory competed internationally. He had been the national champion in the 440 yards in 1951 and 1955 and finished third, behind Gosper and John Goodman in 1956.
