He was a prolific writer on the subject and an avid disciple. He lectured to large audiences in Melbourne and Sydney and attracted considerable attention from the press and antagonism from the church. His final address in Sydney was at the Sydney Town Hall (on this day) 27th November 1920. These illuminated addresses were presented to Doyle in Sydney and Melbourne and are now held in the State Library of NSW.
