After the Olympics, Evans moved to the United States to study business and compete for the University of Arizona. He was less successful in the short-course format used at college level, which placed more reliance on efficient turns. Evans returned to Australia for the 1982 Commonwealth Games in Brisbane, winning silver in the 100 m breaststroke and gold in the medley relay. He competed in his second Olympics in Los Angeles in 1984, winning bronze in both the 100 m breaststroke and the medley relay. Evans retired after missing selection for the 1986 Commonwealth Games and attempted to follow his father into politics. He unsuccessfully stood as the candidate for the Liberal Party of Australia in the electoral district of Perth at the 1986 state election, before pursuing a career in business.
