Australians Face Death Risk in Heatwaves: Study Reveals Cities as Hotspots for Extreme Temperature & HVI
A groundbreaking study conducted by researchers from the University of Queensland and Griffith University has revealed that urban residents in Australia face a significantly higher risk of death during heatwaves compared to their rural counterparts. The research, published in the Environmental Impact Assessment Review in March 2025, examined two decades of temperature and mortality data across Australia’s major cities, including Melbourne, Sydney, Adelaide, Brisbane, Hobart, Perth, and Darwin.
The study utilized the Heatwave Vulnerability Index (HVI) to identify regions most susceptible to heatwave-related fatalities. Even during mild heatwaves, there was a notable correlation between deaths and HVI scores in Australia’s capital cities. The far north and southern regions of Western Aust...
