Trust at the border: identifying risk and assessing credibility on reality television

Every day, officers working at international airports investigate potential risks to state safety and security. But how do they decide who they can trust, and also ensure that the broader public trusts them to conduct this work? This article explores these questions through an examination of the reality television show Border Security: Australia's Front Line. Through critical discourse analysis of a collection of 108 televised airport encounters, we explore the aspects of communication, behaviour, and identity made salient in officers’ evaluations of passengers’ credibility and critically examine the assumptions underlying them. Further, we consider how power and role divisions are implicated in the construction of passenger and officer credibility, both within border encounters and in discourses about them. Our analysis makes a novel contribution to the literature on credibility assessments in intercultural communication, demonstrating how an institutional and social ‘culture of disbelief’ is constructed vis-à-vis certain groups through seemingly banal border work.
