After the games, Konrads accepted a swimming scholarship at the University of Southern California, where his performances decreased over time. Upon returning to Australia to qualify for the 1964 Summer Olympics, he managed only qualification for the 4 × 200 m freestyle relay team. He only swam in the heats, and watched from the stands as another Australian, Bob Windle, claimed his 1500 m title. After retirement, Konrads became a swimming coach, and with his marketing degree from USC, he eventually rose to the Australasian directorship of L'Oréal. He later established a consultancy and advertising firm.
