In 1951, Martin married Gabrielle Hanrahan and worked in Tullamore, a New South Wales country town, as the local GP. He subsequently took his family to England to study surgery. In 1958, he obtained his fellowship of the Royal College of Surgeons of Edinburgh and a year later gained his fellowship of the English College.
