as a turner in Melbourne. He married Muriel Cronan, a clerk who also played piano professionally, on 15 November 1919. They had met before the war and kept in touch throughout Jones' overseas postings. The couple's first child, Ronald, arrived on 2 October 1920. A second son, Ian, would be born on 26 June 1934. Jones was described by family members as being a somewhat distant husband and father, dedicated to his career and rarely given to obvious displays of emotion. Encouraged by a fellow No. 4 Squadron veteran, Harry Cobby, Jones applied to join the new Australian Air Force on 22 March 1921 (the prefix "Royal" was added that August). His rank was flying officer, one below the equivalent of his AFC rank of captain. Another Australian pilot joining the fledgling Air Force was William (Bill) Bostock, who had been a lieutenant in World War I. The pair became firm friends, Bostock acting as something of a mentor to the younger officer. Jones was promoted to flight lieutenant on 1 July 1923.

Posted to RAAF Point Cook, Victoria, Jones was put in charge of the Motor Transport Repair Section and made acting (later permanent) Officer Commanding Workshops. He was highly regarded for his technical and administrative ability but rated only "average" in command and dealing with personnel. In 1926 he took up flight instruction and within a year had been graded a 1A Flying Instructor. He was promoted to squadron leader on 31 March 1927 and given command of the Flying Squadron at No. 1 Flying Training School (No. 1 FTS). Jones spent two years in Britain from 1928, attending the Royal Air Force Staff College, Andover, and graduating top of his class at the RAF's Central Flying School. He later recalled of this posting, "The social life was new to me, as was the etiquette... I learned as fast as I could, but I have no doubt that I unwittingly committed many a social blunder." As the RAAF's senior officer in the UK, Jones had expected to be invited to accompany the airship R101 on its maiden flight to India in October 1930. Instead another
