A former Australian Olympic swimming team physiotherapist accused of sexually abusing multiple children including two Olympians has been ordered to stand trial.Peter John Wells faced a committal hearing in Brisbane late last year, which continued this year.The 55-year-old was facing more than a dozen charges after his arrest in 2022, however several of those were discontinued at the beginning of proceedings and some were replaced with different offences.At the conclusion of witness cross examination on Wednesday, two charges of sexual assault were withdrawn by the prosecution, with the court hearing there was no evidence to offer.However, his lawyer consented to the remaining charges of one count of sexual assault and five counts of maintaining a sexual relationship with a child, to proceed in a higher court.Magistrate Peter Saggers committed Mr Wells to trial in the District Court.When asked if he would like to say anything to the charges or enter a plea, Mr Wells replied, "I plead not guilty, Your Honour".During the committal, the court heard it was alleged the offending occurred between 2002 and 2011 at locations across Brisbane.The court heard some of the offending allegedly involved Mr Wells touching young female athletes underneath their swimsuits indecently during his treatments.Mr Wells has had an extensive career as a physiotherapist, including working for Swimming Australia for several years and was part of the Olympic swimming teams at the Beijing, London and Tokyo Games.He was also the lead physiotherapist at the Australian Olympic Team Headquarters Clinic at the Rio de Janeiro Games.Mr Wells remains on bail with his case to return to court at a later date.
