There is evidence that Asian migrants in Australia may be relatively reluctant to seek professional help for depression. Reluctance may be related to poor mental health literacy, including limited knowledge of help-seeking options and treatments, and a preference to seek help from informal networks. This study investigated Sri Lankan Australians' knowledge about managing depression by examining their hypothetical help-seeking intentions and perceptions about interventions and help-providers' helpfulness. Following Jorm's mental health literacy framework, participants (= 374) were presented with a vignette of a Sri Lankan Australian exhibiting symptomatology consistent with Major Depressive Disorder, and asked to indicate their intentions to seek help by responding to the question: "If you had Mr Silva's problem, what would you do?". Participants also rated the likely helpfulness of various professional and informal helpers and interventions in addressing a problem akin to Mr Silva's. Participants reported being likely to seek help from GPs (35.8%), psychologists (25.7%) and friends (24.3%). Additionally, those who intended to seek informal help were significantly less likely to seek professional help, and vice versa. Furthermore, psychologists (94.1%), counsellors (93.3%), close friends (92.5%) and compatriots (91.4%) were most frequently categorised as helpful. Given participants' high endorsement of psychiatric treatment, psychological treatment, and self-help strategies such as engaging in enjoyable activities, it would be helpful for clinicians to emphasise the benefits of these interventions for managing depression. Additionally, recognising some participants' inclination towards religious practices and helpers, clinicians can consider integrating these help-seeking behaviours into therapeutic approaches. Future research is warranted to examine the predictors of help-seeking intentions.
