Mopio-Jane was invited by FINA to compete as a lone female swimmer for the Papua New Guinean squad in the 50 m freestyle at the 2008 Summer Olympics in Beijing. Swimming on the outside lane in heat six, Mopio-Jane put up a marvelous swim to hit the wall by nearly three tenths of a second (0.3) behind leader Rugilė Mileišytė of Lithuania, with a second-place time and lifetime best of 26.47; however, she finished outside the semifinal cut in forty-second overall.
