After a couple of sub-par competition results in 2011, Ballard made big changes to her diet, gloves, technique, chair position, and training regime. She entered the 2012 London Paralympics ranked world number one in both the T53 100 m and 200 m. At the games, Ballard participated in the T53 class events for 100 m, 200 m, 400 m and 800 m events. She won two silver medals in the 200 m and 400 m T53 events, and a bronze medal in the 100 m T53 event. At the 2016 Rio Paralympics, she won bronze medals in the women's T53 100 m and 400 m. At the 2020 Tokyo Paralympics, she was a finalist in the women's T53 100 m, 400 m, and 800 m. She came 7th in 100 m, 7th in 400 m and 7th in 800 m. World championships In August 1998, Ballard competed at the International Paralympic Committee World Championships in Birmingham, England, where she was part of the gold medal-winning Australian women's 4 x100 m and 4x400 m relay teams. Both relay wins set long-standing world records. In the 2002 World Championships, she won gold in the 100 m. At the 2013 IPC Athletics World Championships in Lyon, France, she won silver medals in the Women's 100 m, Women's 200 m and Women's 800 m T53 and a bronze medal in the 400 m T53. At the 2015 IPC Athletics World Championships in Doha, Ballard won gold medals in the Women's 200m T53 in a championship record time of 29.33 and the Women's 400m T53. After winning the 400 m, Ballard said: "This is the one I wanted. I was so nervous coming in, you try and tell yourself that the worst thing that can happen is a loss and starting again tomorrow, but the reality is that this matters so much. I was so scared before the race, perhaps it gave me the adrenalin to get it done. I've just worked so hard for this for so long." She also won a bronze medal
