Gary Eddy (athletics) competed at the 1966 and 1970 Commonwealth Games and the 1964 Tokyo Olympics in events ranging from the 100m through to the 400m and in relay teams of the same lengths. At the Kingston Games in 1966, Eddy finished fifth in the 100 yards and fourth in the 220 yards, before winning a bronze medal in the 4×110 yards relay team, and completed his Games running in the heats of the 4×400 yards. Eddy made the final of the 100m in Edinburgh four years later running 10.34 seconds (wind assisted). After a 7th place finish in the 200m, Eddy joined the Australian 4x100m relay team but the team dropped the baton and failed to win a medal. Eddy was the 1965 Australian 220 yards and 1966 Australian 400m champion.
