[1] Trained by Forbes Carlile, and making her international debut as a 14-year-old prodigy, Moras was expected to win medals at the 1968 Mexico City Olympics.

She struggled, however, to adapt to the rarefied air at high altitude conditions and required medical treatment for breathing difficulties and hyperventilation.

Despite this Moras managed to salvage a bronze medal in the 400-metre freestyle, behind the American duo of Debbie Meyer and Linda Gustavson.

Moras qualified to represent Australia at the 1972 Summer Olympics in Munich in the 400- and 800-metre freestyle and the 400-metre individual medley, but failed to reach the final in any of the events.
