In 1969, he was appointed Specialist in Rehabilitation Medicine at both Prince Henry and Prince of Wales hospitals and Deputy Director of the Department, as well as Clinical Director of the Spinal Injuries Unit in 1974. The rehabilitation unit established at the Prince of Wales hospital between 1955 and 1960 included a Paraplegic Ward, due to many patients being severely impaired and needing extended rehabilitation because of the severe Polio epidemic. Jones was the driving force behind the establishment of the Post-Polio Clinic at Prince Henry hospital, the patients with spinal cord injuries being transferred from the Prince of Wales Hospital, Sydney in 1965. George Burniston, the first Director of Rehabilitation Medicine at Prince Henry and Prince of Wales hospitals, was to influence Jones; they established a rehabilitation service for amputees, for spinal injured patients and later for stroke patients. Jones together with his colleagues Doctor John Baggott and Professor Ben Marosszeky set up the first regular clinical meetings at the Prince of Wales hospital, later known as the Registrar Training Programme. Jones felt that social rehabilitation was the next step in saving the lives of paraplegics. From 1972 to 1997 he was a Director of the Paraplegic and Quadriplegic Association of New South Wales, the key goals being to lobby for a specialized Spinal Injuries Unit of which he was a Director, and accommodation for people with severe spinal cord injuries. In addition, Jones was a member of the Hostel, Welfare and Workshop Sub Committees of this association and a doner as well. Jones' first experiences as team doctor were at the National Titles in 1973, the 1974 Commonwealth Paraplegic Games, and the 1976 Toronto Paralympics. To ease the burden of financial difficulties for New South Wales wheelchair athletes competing at the 1976 Games, Doctor Jones raised $1400 towards his own expenses. Jones who was at the time Clinical Director of the Spinal Injuries unit, Prince Henry Hospital Sydney, organised and participated in a 'wheelathon' in the Sutherland Shire of Sydney and raised $400.00 towards the cost of sending Indigenous Australian Paralympian Ray Barrett to the Stoke Mandeville Games in England. Appointed team doctor at the 1977 FESPIC Games, Parramatta NSW the first multi-diagnostic Games held in Australia, Jones was assigned to care for amputee athletes, who formed the Australian Amputee Sporting Association during the Games, as no such organization had previously existed.
