Martin made her debut for Australia at the 2014 Japan Goalball Championships as part of the development squad.[3] She is classified as a B3 competitor.[3] In May 2015, she was a member of the Australian Women's Goalball team which came fourth at the IBSA World Games in Seoul.[5] She was a member of the Australian team that finished third at the 2015 IBSA Goalball Asia/Pacific Qualifying Tournament in Hangzhou, China. The Belles therefore failed to qualify for the 2016 Paralympics.[6] They were displaced to allow for an African team, Algeria as it turned out, to compete in goalball for the first time.[7] But following the re-allocation of Russia's spot, the Belles found themselves getting a last minute invite to Rio. They entered the tournament ranked ninth in the world.[8] They performed better this time, fighting Uzbekistan to a draw, but they needed a win or draw in their final game against Canada to progress to the quarter finals, but lost 6–0, ending their second Paralympic campaign.[7]
