A late 2024 report has revealed that Australia outpaces the lifespan of all other English-speaking countries in the world by an average of one to four years per person. A new 2025 study pinpoints exactly where these hardy long-life Australians are likely living, with some areas now identified as centenarian hotspots.
The study by leading longevity brand, Simply Nootropics cross-references recent Australian Bureau of Statistics (ABS) data on lifestyle habits to identify blue zones. This is then cross-referenced with age census data identifying people over 85 years old in every Aussie postcode; the results offer a detailed map pinpointing the exact areas where people are most likely to celebrate their 100th birthday in Australia, based on lifestyle habits and people who have aged well in that area.
The Places You’re Most Likely To Live to 100 Years Old:
With the data scrutinised and mapped throughout all of Australia, the results showcase a landslide leaning toward rural, outdoorsy areas, with not one city ranking this 2025:
•Queenscliffe, Victoria – 6.49% over 85, blue zone score 1.
•Victor Harbor, SA – 5.44 % over 85, blue zone score 2.
•Narembeen, WA – 5.28% over 85, blue zone score 3.
•Orrorro Carrieton, SA – 4.61% over 85, blue zone score 4.
•Claremont, WA – 4.66% over 85, blue zone score 5.
•Buloke Vic – 4.74% over 85, blue zone score 6.
•Hindmarsh, Vic – 4.7% over 85, blue zone score 7.
•West Wimmera, Vic – 4.63% over 85, blue zone score 8.
•Hunters Hill, NSW – 5.11% over 85, blue zone score 9.
•Weddin, NSW – 4.51% over 85, blue zone score 10.
Simply Nootropics researcher and a neuroscientist who specialises in longevity and health, Dr Brian Ramos says: "The results of this study offer a chance for us to question our lifestyle habits and to cross-check our daily routine with that of those who’re 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.
"It is important for those living in major metropolitan areas to schedule downtime regularly, form community and ensure time is spent in green areas designed to help the brain unwind from the daily stresses life can bring.”
Queenscliffe, Victoria, is the Australian region where you're most likely to reach 100 based on comprehensive data looking at the percentage of those who’ve made it to old age (85+) in the area, along with its residents' lifestyle habits making it an official blue zone. Surprisingly, If there is one thing we can learn from Victorian lifestyle data, it is that it is never too late to adopt healthy habits, with the over 65s+ hitting more habitual health targets in their day-to-day than younger people.
ABS data shows Victorians fare well against Australia’s fruit and vegetable intake guidelines, which is two servings of fruit and five to six servings of vegetables each day; interestingly, the data shows that the portion of those guidelines met increased with age, with 50.4% of those over 65 eating the guideline amounts of fruit and veggies, a statistic unique to Victoria.
Victorians are becoming increasingly more active, with recent reports showing that activity levels have almost doubled since 2017, jumping from 16.8% to 25% meeting activity guidelines. Outstandingly, activity levels increase with age in Victoria with a huge 35% of 65+ year-olds meeting activity guidelines, higher than any other age group; suggesting once more that it is never too late to start working on your longevity.
Roslyn Walker, producer at Australia’s The 100 Project, a platform that celebrates the lives of Australia’s centenarians, weighs in on what they think it takes to become a centenarian. Roslyn comments: "Centenarians have vastly different life experiences but they have generally been busy and active people and engaged with their communities.
"We have noticed that centenarians are realists; pragmatic about bad things that have happened in their lives, passionate about the good things and they all have a dry sense of humour. "
Victor Harbour, South Australia, ranks second with 5.44% of its population over 85. It’s also joined in the top 10 by Orroroo Carrieton, in South Australia, at 4.61%. Since 2001, smoking rates in South Australia have dropped to 9.7%, with nearly 60% of the population being non-smokers. Additionally, 23.3% walk regularly, a stat that is a major contributing factor to why this state ranks second for overall lifestyle habits.
Other notable regions include Narembeen and Claremont in Western Australia, ranking third and fifth place with 5.28% and 4.66% of their populations over 85, respectively. While Western Australia 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.
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 centenarian hotspot in the future.
