There are few issues that have been as vexing for the Australian healthcare community as the Australian governments policy of mandatory, indefinite, immigration detention. While many concepts have been used to begin to describe the many dilemmas faced by healthcare professionals and their resolution, they are limited, perhaps most fundamentally by the fact that immigration detention is antithetical to health and wellbeing. Furthermore, and while most advice recognises that the abolition of detention is the only option in overcoming these issues, (...) it provides little guidance on how action within detention could contribute to this. Drawing on the work of political theorists and the broader sociological literature, we will introduce and apply a form of action that has not yet been considered for healthcare workers within detention, resistance. We will draw on several examples from the literature to show how everyday resistance could be enacted in healthcare and immigration detention settings. We argue that the concept of resistance has several conceptual and practical advantages over much existing guidance for healthcare workers in these environments, namely that it politicises care and has synergies with other efforts aimed at the abolition of detention. We also offer some reflections on the justifiability of such action, arguing that it is largely consistent with the existing guidance produced by all major healthcare bodies in Australia. (shrink)
