Abstract
<title>Abstract</title> <p> <bold>Background</bold> Informal cancer carers report high unmet needs. However, few studies have examined experiences and support needs among carers from priority population groups, including those from culturally and linguistically diverse (CALD) communities, rural/remote areas, and carers from lesbian, gay, bisexual, transexual, intersex, queer, asexual plus (LGBTIQA+) communities. <bold>Aims</bold> This study aimed to explore supportive care and health service experiences of informal cancer carers from priority population groups in Australia. <bold>Methods</bold> Online focus groups were conducted by specialist agencies with experience working with people from priority populations. Semi structured focus groups explored carer experiences with health providers and services, access to supports and resources, and recommendations for system improvement. Sessions were digitally recorded, transcribed, and analysed using thematic analysis. <bold>Results</bold> Eight focus groups were conducted with a total of 41 carers (n = 17 rural/remote; n = 8 LGBTIQA+, n = 16 CALD). Most carers were women (n = 28;68%), with the most common age group was 18–39 years (n = 16;39%). While some positive experiences were reported, many carers highlighted challenges and areas for health system improvement. Main themes included isolation in the care role, absence of information provision, limited coordination of services, inadequate communication with health providers, and lack of recognition of carers as part of the care team. <bold>Conclusions</bold> Despite longstanding calls to recognise family carers as integral members of the care team, this remains limited in practice. Establishing pathways to connect carers with appropriate and tailored support is a priority. Future research should evaluate models that embed carer support into routine cancer care to improve outcomes. </p>
