Despite having played wheelchair basketball at junior level, she preferred the solo aspect and self-reliance that comes with athletics. Kamlish made her senior international debut at the 2012 Paralympic World Cup in Manchester and that year was selected for the Great Britain team at the London Paralympics. At the London Games she was selected for two events, the 100 metres and 200 metres T44 sprints. Kamlish qualified through the heats in both events but did not achieve a podium finish in either, though she did achieve a personal best in the 200m.
