Positive doping test
Jack pulled out of the 2019 World Aquatics Championships days before it started, citing "personal reasons". It was later revealed that Jack had tested positive for the anabolic agent Ligandrol, which is popular with bodybuilders, during an out-of-competition test held by the Australian Sports Anti-Doping Authority (ASADA); a follow-up sample further confirmed the banned substance in her system, and she was subsequently suspended by Swimming Australia and investigated by ASADA. She posted on Instagram saying that she "would never intentionally take a banned substance that would disrespect my sport and jeopardise my career". The investigation by ASADA was ongoing as of 29 July 2019.
The result of the investigation was unintentional ingestion of ligandrol by Jack and a 24 month suspension by the Court of Arbitration for Sport running from 12 July 2019 through 11 July 2021 for the anti-doping rule violation. In September 2021, after Jack served the entirety of the imposed suspension, the Court of Arbitration for Sport upheld the suspension as served in full when challenged by Sport Integrity Australia and that Jack could return to competition.
