In 1928 Dr Rumble began a Sunday evening programme on radio-station 2UE, answering queries about Catholicism. Dr Rumble's 'Question Box' was transferred to the Catholic station 2SM and continued until 1968.[5] It became "the most famous religious program on Australian radio."[6] It answered questions sent in by listeners, often hostile ones from Protestants. He treated inquirers as honest seekers for the truth and answered in a very logical style "in a voice like worn sandpaper".[3] He criticised the "puritan element" as well as the "Godless secularism" of Australian society.[7]
Written versions of his Question Box program were popular in the United States (where he toured successfully in 1940-41[8]) as well as Australia and were said to have sold seven million copies.[3]
