The Ageing Revolution calls for policy systems that detect vulnerability earlier and respond equitably to culturally and linguistically diverse older populations. Chinese-speaking older adults remain under-represented in the evidence informing community screening, service planning, and aged care reform in Australia. This study examined multidomain functional cognition and pre-dementia indicators in 144 community-dwelling Chinese-speaking older adults in metropolitan Australia. Participants completed the AD8, Healthy Brain Ageing Functional Assessment Questionnaire, Geriatric Depression Scale, and frailty-related measures. Analyses included descriptive profiling, exploratory factor and component analyses, correlations, and regression modelling. Findings showed substantial chronic disease burden, notable psychosocial vulnerability, and patterned early difficulties across cognition and everyday functioning. The AD8 identified three domains: memory impairment, executive and interest decline, and functional recall difficulties. Broader functional analyses showed strong interrelationships among memory, higher-level thinking, sleep, and behavioural change. Key indicators, including judgment problems, repetition, financial difficulties, tool-use difficulties, and daily memory concerns, were associated with psychosocial vulnerability and functional limitation. These findings suggest that early decline is multidimensional and culturally contextual, but not well captured by reactive, diagnosis-driven models alone. Policy reform should embed culturally responsive, multidomain screening into community and aged care pathways to strengthen ageing-in-place strategies, improve equity in access to support, and guide more inclusive planning for diverse older populations. In line with The Ageing Revolution: Innovation and Opportunity, early culturally informed detection offers a practical lever for prevention, service redesign, and system change. This approach can better align research evidence, practice, and policy investment for ageing well in diverse communities.
