The number of dementia cases in the nation is expected to more than double, surpassing one million by 2065.

As the country’s leading cause of death, dementia profoundly impacts both those who suffer from it and their loved ones.

Recent data indicates that approximately 29,000 individuals between the ages of 18 and 65 are currently living with young onset dementia, a figure that could rise to around 41,000 by 2054.

In New South Wales alone, there are about 145,700 people living with various forms of dementia as of 2026, with projections suggesting this number could climb to 252,800 by 2054.

Professor Tanya Buchanan, the CEO of Dementia Australia, highlighted the rapid increase in dementia diagnoses.

“There is an urgent need for a nationwide initiative to promote brain health throughout our lives, alongside the necessity for quality care and support services for people of all ages affected by dementia, as well as their families and caregivers,” stated Professor Buchanan.

“Dementia Australia is calling for essential investment from the federal government in implementing the National Dementia Action Plan, a ten-year government framework released in late 2024 aiming to improve the lives of people living with dementia and their carers.

“Australia is recognised internationally for its strengths in dementia care, support and research, but the system still has areas that need improvement. 

“Funding the delivery of the National Dementia Action Plan is essential for all Australians impacted by dementia.”
