On the first night of the Games, Koschischek won the third heat of the 100 m butterfly, by 0.28 of a second ahead of Hong Kong's Hannah Wilson in an Austrian record of 59.07, but she missed out the semifinals by 0.58-second deficit, as she placed twenty-sixth out of 69 swimmers in the preliminaries. In the 100 m freestyle, Koschischek posted a lifetime best and another Austrian record of 55.62. She raced to third place and twenty-ninth overall by a hundredth of a second (0.01) behind Arianna Vanderpool-Wallace of the Bahamas.
