Swimming Australia CEO Leigh Russell has described the Shayna Jack positive drug test as bitterly disappointing and embarrassing for the national swimming team, the sport and the country.
She says SA's agreement with national anti-doping body ASADA did not allow it to reveal news of Jack's test at the time when she was sent home from the team's training camp in Japan ahead of the world championships in South Korea.
She also says Jack is entitled to a fair process as the matter is investigated and the swimmer was planning to reveal the positive test on her A sample this week once the national team had finished competing.
