Austin was born in Ascot Vale, Victoria, Australia, and from 1927 to 1931 was a student at Melbourne Grammar School. For three years, he was a member of the school's 1st XI cricket side and was captain in his final year. He was a resident of Trinity College within the University of Melbourne and graduated as a Bachelor of Arts. In 1936 he was elected Victorian Rhodes Scholar and in 1937 entered Christ Church, Oxford.
While at the University of Oxford, Austin won a Blue in cricket as a right-hand batsman, bowling leg-break, and googly. He was later awarded a Master of Arts, 1943, and a Bachelor of Divinity from the University of London.
Austin then served as the Professor of Classics and Ancient History at the University of Western Australia (UWA) from 1952 until 1978 and was chairman of the Professorial Board in 1963 and 1964. After his retirement from the university he was appointed emeritus professor and was the Warden of Convocation from 1980 until 1982. A trust funds a bursary for students of Ancient Greek in memory of Austin's considerable contributions to the study of Greek, the classics and ancient history at UWA. This has now been converted to support a fund for visiting lecturers.
