Dlamini received a Universality invitation from FINA to compete as a lone female swimmer for the Swaziland team in the 50 m freestyle at the 2008 Summer Olympics in Beijing. Swimming on the outside in heat four, Dlamini smashed the 28-second barrier to take the second spot with a personal lifetime best of 28.70, but fell behind the winner Ximene Gomes of Mozambique by more than half a second. Dlamini failed to advance to the semifinals, as she placed sixty-first overall out of ninety-two swimmers in the prelims.
