Dissatisfied with his job, he successfully applied for a position in the civil service in Salisbury, Rhodesia, in 1927 aged 18.^[1] He made his first-class debut a few months later, but was only moderately successful, making the top score of 25 in Rhodesia’s first innings of 135.^[2] Eighteen years later he resumed his first-class career, but he was even less successful, scoring only 40 runs and taking four wickets in four matches.^[3]

Austin was appointed Companion of the Imperial Service Order in 1963 for his service as Deputy Secretary in the Ministry of Local Government in Rhodesia.^[4] At the time of his death in Harare in 2004 at the age of 95, he was the oldest surviving Rhodesian cricketer.^[1]
