Broadcast radio began in the late 1920s and early 1930s and quickly gained an educative mission that spanned from schools to adult education on specific topics, including the building of civic values in the public as a whole. Robert Cummings, architect and aspiring university teacher, heard broadcasts on architecture from his teachers at the Architectural Association in London and emulated these on his return to Australia in 1930. The chapter puts Cummings architecture talks on the Australian Broadcasting Commission from 1933 to 1937 in the context of architecture on the wireless in the UK and Australia and the kind of talking and listening that wireless architecture required. For Cummings, as a proponent of architectural modernism, the wireless was not only a medium for education, its technological novelty made it an object lesson in the experience of modernisation.
