A new study of postcode age data and lifestyle habits has pinpointed where you’re most likely to live to 100 in Australia, with two places in WA making the top 10.
The study by longevity brand Simply Nootropics cross-referenced recent Australian Bureau of Statistics data on lifestyle habits to identify blue zones, or places where hardy long-life Australians were likely living, with some areas now identified as centenarian hotspots.

This was cross-referenced with age census data identifying people over 85 years old in every Australian postcode, with the results offering a detailed map pinpointing where people were most likely to celebrate their 100th birthday based on lifestyle habits and people who had aged well in that area.
Narembeen and Claremont ranked third and fifth, with 5.28 per cent and 4.66 per cent of their populations over 85, respectively. Queenscliffe in Victoria was crowned the Australian region where people were most likely to reach 100.
Longevity neuroscientist Brian Ramos said WA could be the nation’s future long-life blue zone.
“While WA has a lower likelihood of producing centenarians based on age data, it ranks first – above any other Australian state or territory – for lifestyle factors that contribute to longevity,” he said.
“With its strong performance in areas like BMI, alcohol consumption, physical activity, and diet, Western Australia is the healthiest state in 2025 and could be on its way to becoming Australia’s number one centenarian hotspot in the future.”
Ramos said the study’s results were a chance to question our lifestyle habits and cross-check our daily routine with those who were living in the blue zones.
“These areas all share qualities in common, peaceful surroundings, a slower pace of life and ample space for outdoor activities,” he said.
