Guardian Australia has made a strong commitment to covering Indigenous affairs, offering an alternative approach to other mainstream Australian news media since its establishment in 2013. In this article, the concepts of boundary work and boundary-drawing power provide a framework for analysing how Guardian Australia negotiates, extends, and concedes its professional journalistic ground in ways that support more diversity in news-making in the space of Indigenous affairs. In doing so, the article looks beyond Guardian Australia’s award-winning journalism to its “everyday” coverage of Indigenous affairs. Through a content analysis of 1048 items published between March 2018 and February 2020, it identifies and discusses who contributes or produces the content, the types of content and the range of stories that are covered, and how Guardian Australia itself categorises these stories. Our analysis finds that Guardian Australia’s Indigenous affairs coverage presents more sustained and diverse reporting than previous studies of legacy media have found, and its content expands journalistic boundaries by embracing the affordances of digital networked media and the contributions of diverse First Nations writers.
