Australia's Asthma Deaths Hit Decade-High, Dementia Surpasses 10% of All Deaths for First Time

New data from the Australian Bureau of Statistics reveals that asthma deaths in Australia have reached their highest level in a decade, while dementia—including Alzheimer's disease—now accounts for more than 10% of all deaths for the first time. In 2025, there were 188,421 deaths registered, with 19,019 attributed to dementia, making it the leading cause of death in Australia since 2024. The rise in dementia deaths highlights the growing impact of an ageing population and the urgent need for improved care and research funding. Meanwhile, the decade-high asthma mortality rate raises concerns about air quality, access to healthcare, and management of chronic respiratory conditions. These trends underscore significant public health challenges that require coordinated policy responses and increased awareness among Australians. As the nation grapples with these shifts, the data serves as a critical call to action for healthcare providers and policymakers.
