William Ardagh Gardner Walter (13 August 1860 – 10 March 1940) was magistrate of Kalgoorlie, Western Australia. William enjoyed his education at Taunton College School and the University of Oxford. At Oxford he shone at Rugby football, cycling and as a rower in the Eight for Exeter College Boat Club. In 1920 he left the goldfields to become magistrate in Perth. He remained there until May 1924 when he was compulsorily retired by the newly elected Collier Labor government. Collier was blamed for victimization, but the administration remained adamant.
