Background: Settlement service literacy refers to the ability of migrants to access, understand and critically navigate settlement services. In Australia, increasing numbers of culturally and linguistically diverse migrants require settlement services to assist their transition. However, there are barriers to migrant’s ability to utilise settlement services which are related to their level of settlement service literacy. This review aims to shed light on how settlement service literacy influences new migrant’s utilisation of settlement services, and the consequences that it has for health, well-being and sense of belonging. Methods: The review will follow the guidelines laid out by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Literature searches will be undertaken in CINAHL, EMBASE, PubMed, PsycINFO, Scopus, Web of Science, Sociological Abstracts, SocIndex, ProQuest Social Science Database, and Google Scholar. Grey literature and relevant government bodies, non-government organisations, service providers and research institutes will also be searched. Studies included will report primary data (qualitative and quantitative) on new migrant’s (under five years) ability to utilise settlement services in high income countries. Studies that meet the inclusion criteria will be imported to Covidence, two researchers will screen the studies in a two part process (title and introduction scan; and full text) for relevance. Data extracted will include general publication information (author, country, year, and publication), type of study, participants, type of settlement service, measured outcomes, and the study aims, methods and results. Finally, data will be synthesised using a narrative approach. Discussion: The review will provide insight into the relationship between settlement service literacy and service utilisation and wellbeing for new migrants. The review will also provide data to inform settlement service policy to better cater for the needs of migrants. Systematic review registration:This protocol has been submitted to international prospective register of systematic reviews and meta-analysis (PROSPERO) and is currently under review.
