Victorious Caitlin Parker believes the Olympics' approval of two boxers who had failed gender eligibility tests is "incredibly dangerous" ahead of a potential showdown with one of her teammates in Paris.
Australian boxing captain Parker led from the front on Wednesday, dominating Mexico's Vanessa Ortiz with a unanimous 5-0 points decision to reach the quarter-finals of the 75kg division.
It followed an earlier loss for Shannan Davey to Bulgaria's Rami Mofid, but Charlie Senior (57kg) is also just one win away from a medal after beating Belgium's Vasile Usturoi 4-1.
