This article explores how three Victorian country newspapers shaped and reinforced the collective memory of Anzac Day in its first decade, from 1916 to 1925. It draws on a sample of 300 articles, and looks to scholarship on journalism and memory to generate understandings of these newspapers' important role as co-creators and protectors of Anzac Day commemoration. The sample provides evidence that Anzac Day coverage was thematically consistent from the start. The analysis highlights journalists' roles as patriotic cheerleaders for a new, national identity; as collaborators with other social institutions in establishing the commemoration tradition; and as boundary riders, who patrolled less than acceptable Anzac Day behaviour. This role is most striking when communities failed to mark Anzac Day in the early years, as this article reveals.
