ABSTRACT Sport plays an important role in the conception of Australian national identity. Much of the scholarly work on this topic has concentrated on professional, high-profile sports and athletes. In this article, we draw attention to a highly symbolic aspect of popular sporting culture—school sports houses—and the prominent historical figures and motifs that they project through their team names, mascots and colours. School sports houses are potent examples of banal nationalism, whereby elements of Australianness are reinforced through the tradition of school athletics and swimming carnivals. Here, we highlight the overlap between the school-based agenda of encouraging group identity and the broader notion of the nation as an imagined community. Using a comprehensive dataset of Queensland high school sport houses in 1969 and 2023, we observe several trends, such as the persistence of houses named after colonial explorers and the disparity between houses with women’s and men’s namesakes. We consider the role of school sports houses as “identity primers”, or scripts, that encourage schoolchildren to identify with specific historic figures, landforms, animal totems, character traits and other qualities as indicators of the region and nation in which they live.
