UNSW AI Companions Tackle Elderly Loneliness Crisis in Australia

Understanding the Loneliness Crisis Among Australia's Elderly

Australia's ageing population is facing a profound challenge: widespread loneliness, particularly among older adults in residential aged care. Recent surveys indicate that around one in five Australians over 75 experience loneliness, with rates climbing higher for those living alone or in regional areas. In aged care facilities, the situation is even more acute, where up to 61% of residents report feeling lonely, and individuals spend nearly half their waking hours alone. Staff availability is limited to about 30 minutes per resident per day, exacerbating isolation and contributing to an annual health system cost of $2.7 billion linked to loneliness-related issues. 74 73

This epidemic not only impacts mental health, doubling the risk of chronic diseases like dementia and depression, but also underscores a critical gap in psychosocial support. Universities like the University of New South Wales (UNSW) are stepping in with innovative research to bridge this divide.

UNSW's Skilled Companions: A Groundbreaking Initiative

At the forefront of this effort is UNSW's Skilled Companions project, a spinout startup developed through collaboration between the Big Anxiety Research Centre, the UNSW AI Institute, and the Centre for Healthy Brain Ageing (CHeBA). Launched as a prototype at Technology Readiness Level 5, the initiative has secured AUD 1.1 million in grants and AUD 2.6 million in customer commitments, signaling strong potential for scaling. 72

Skilled Companions features lifelike digital characters powered by custom AI, informed by lived experience data and psychological expertise. Unlike generic chatbots, these companions proactively engage users, understand context, and provide tailored psychosocial support. The project targets older adults, those with disabilities, and anyone grappling with emotional distress, offering a B2B SaaS model for aged care providers.

Meet Viv: The Star AI Companion for Dementia Support

Viv stands out as the flagship character, co-designed specifically with women living with mid-stage dementia. She serves as a patient conversational partner, prompting users to identify emotions, reflect on coping strategies, and reminisce about positive memories. Viv shares relatable experiences from a dementia perspective, offering empathy like, "Yes, dear, I know exactly what you mean, I've struggled with that too," rather than generic advice.

Other characters include Richard, Lou, Sophie, Harry, and Willow, each tailored for diverse needs such as anxiety, grief, or physical safety concerns. These screen-based companions, deployable on TVs or tablets, provide 24/7 availability, filling gaps when human interaction is scarce.

The Co-Design Process: Community-Led Innovation

What sets UNSW's approach apart is its emphasis on co-design. Researchers, including Professor Jill Bennett (Chief Scientific Officer and head of Big Anxiety), Dr. Gail Kenning (Chief Product Officer), Professor Michael Thielscher (Chief Technology Officer and AI Institute expert), and CEO Robert Buhrke, incorporated feedback from dementia patients and aged care communities. This ensures cultural sensitivity, with plans for multilingual support like Hindi and subtitles for hearing impairments.

The process involved iterative testing to make interactions natural, avoiding frustration from repetitive stories—a common dementia trait—while exercising cognitive functions like memory and language.

Pilot Trial Results: Promising Evidence from Leigh Place

A five-week pilot at Leigh Place aged care facility in Southwest Sydney involved 12 residents. Participants reported a 16% reduction in loneliness scores, with some engaging in conversations up to two hours. Residents described Viv as a "lovely lady… really open… a nice person to talk to," praising her non-judgmental listening.

Dr. Suraj Samtani, a CHeBA postdoctoral fellow and clinical psychologist leading the evaluation, noted: "Every conversation exercises the brain—memory, language, attention, emotional processing." Challenges included hearing issues and occasional conversational glitches, but overall, the AI complemented human care effectively. 74

For resident 'Rose,' Viv patiently revisited traumatic childhood stories without boredom, providing vital emotional outlet.

Expert Perspectives: Balancing Optimism and Caution

Professor Jill Bennett emphasizes that AI companions do not replace human connections but enhance them: "AI is the defining technological conversation of 2026… yet in residential aged care, loneliness is central." Tanya Petrovich from Dementia Australia highlights partnerships scaling impact.

However, Monash University's Professor Robert Sparrow cautions that over-reliance could worsen isolation, urging ethical design to avoid dependency. 31 UNSW addresses this by positioning AI as a supplement, promoting real-world connections.

Technical Underpinnings: Advanced AI Planning

Powered by AI planning algorithms from UNSW's AI Institute, these companions anticipate needs, gently challenge negative thoughts, and adapt to user states. Unlike reactive tools like ChatGPT, they draw from psychosocial expertise and lived data for proactive, empathetic interactions. Future enhancements include voice modulation for human-like tone and integration with AR/VR for immersive experiences.

Challenges and Ethical Considerations

Despite promise, hurdles remain: accessibility for non-English speakers, digital literacy, and privacy. UNSW prioritizes inclusivity, with pilots showing older adults embrace tech when introduced thoughtfully. Ethical concerns like dependency are mitigated by design limits encouraging human outreach.

Broader Australian context includes government inquiries into aged care loneliness, aligning with UNSW's scalable solutions reimbursable via programs like NDIS.

Implications for Australian Higher Education and Research

UNSW exemplifies how universities drive societal impact through interdisciplinary research—merging AI, psychology, and health ageing. As a UNSW Founders spinout, it fosters innovation ecosystems, attracting investment and jobs in AI ethics, aged care tech, and clinical trials. This positions Australian higher ed as leaders in AgeTech, addressing demographic shifts where seniors will comprise 23% of the population by 2050.

Collaborations with Harvard and Fudan University expand global reach, emphasizing community-designed solutions.

Stakeholder Views: From Residents to Providers

• Residents: Value emotional safety, endless patience.
• Care Providers: Appreciate scalability, staff relief (high margins via subscriptions).
• Families: Peace of mind via 24/7 monitoring.
• Government: Cost savings on $2.7B loneliness burden.

Aged care CEOs note AI's role in person-centered care amid workforce shortages.

Future Outlook: Scaling and Larger Trials

Next steps include a randomized controlled trial (RCT) for robust evidence, multilingual expansions, and B2B rollout. With AUD 2.6M commitments, commercialization via white-labeling and prescriptions looms. UNSW envisions AI companions transforming aged care, integrating with telehealth and wearables for holistic support.

As Australia grapples with 21-23% senior population projection, university-led innovations like this offer actionable paths forward.
