Overview: People living with dementia and their care partners in the community can experience a range of unmet needs which impact on their health and wellbeing. European researchers have developed an innovative web-based platform that provides information and support to better meet the needs of people living with dementia and their care partners in the community. We will adapt the web-based platform so it is suitable for the Australian setting and determine whether use of the platform can improve the health and wellbeing of people living with dementia and their care partners. Community-dwelling people with dementia and their care partners will be randomised as dyads to receive either the intervention or usual care. Dyads in the intervention group will receive access to the platform which providers evidence-based information and techniques to manage dementia-related challenges, health and wellbeing. The benefits of the intervention will be estimated from data collected from dyads at 3, 6 and 12 months follow-up. The primary outcome is the quality of life of the dyad. The impact of the intervention on secondary outcomes including: depression, social engagement, activities of daily living functioning, impact of caregiving, and cost will also be assessed.
