After World War II, Merv Moy joined his local YMCA in Sydney at the age of 18 and embarked upon a decade-long career in national and international basketball. The pinnacle of his time as an athlete came when he was selected to represented his country at their home Olympics in Melbourne in 1956, where Australia was eliminated in the quarter-finals and placed 12th overall after winning only two of its seven matches in the tournament. By career he was a police officer and, after his retirement from active competition, worked his way up through the New South Wales Police Force to the rank of chief inspector.
