Researching marginalised groups is challenging and fraught with ethical issues. These issues can be exacerbated when the researcher is an outsider. Migrant sex workers are a marginalised group due to their position as a sex worker and their migrant status. For outsiders undertaking research with these groups there is the potential for their personal beliefs and moral views around migration, sex work, race, gender and sexuality to influence research methodology, analysis, interpretation and outcomes. Often this has resulted in migrant sex workers being portrayed as victims in need of help, rather than as active, self-determining agents. Much of the research relating to migrant sex workers and trafficking has taken place in institutionalised settings. In such settings, there is good reason for migrant sex workers to identify as coerced victims in need of help rather than as willing migrants who have experienced bad workplace situations and/or who have engaged in alternate migration pathways. Research of this type is usually conducted in detention centres or refuges or worse still – citing difficulties in accessing this population, some researchers will only interview service providers and make conclusions without ever speaking to the target population the research makes claims about. Insiders can more readily gain full and uncompromised access to sex workers affected by trafficking policy outside of institutional settings. In this paper using an example from Scarlet Alliance, Australian Sex Workers Association, we argue for more insider research. We present our methods and discuss how insider led migrant sex work research can lead to credible research outcomes and have many broader benefits for our community.
