John Kelly was born in Ayr, Queensland, on 12 September 1943, the son of John Kelly, a general practitioner and superintendent of the Ayr District Hospital. He was educated at the Marist Brothers College in Ashgrove, Brisbane, and studied medicine at the University of Queensland. After junior posts at the Royal Brisbane Hospital, where he met his future wife Shelly Parer, he went to England to specialise in ENT surgery, and was a registrar at the Royal Surrey County Hospital, being on duty when the victims of the 1974 Guildford IRA bombing attack were admitted. Later, he was at the Royal Free Hospital under John Ballantyne and John Groves. On his return to Australia he set up in practice at Southport and Palm Beach, where, in addition to surgery, he developed a passion for windsurfing, gardening and classical music. Early in 2004 he was found to have metastatic colorectal cancer, and died on 23 May 2004, leaving his widow and three daughters (Caroline, Krissi and Georgie).
