How much is too much? New program helps older Australians rethink their drinking

More older Australians are drinking at risky levels than many realise — and it can have a bigger impact on health than expected.

A new Australian study has found that a simple online program can help people aged 60 and over reduce their alcohol intake, offering a practical way to improve health and lower the risk of long-term harm.

Why this matters

While overall drinking rates have declined in Australia, risky drinking in later life has remained steady — and in some cases, increased.

Nearly one in five Australians in their 60s exceed recommended drinking guidelines. Over time, that can increase the risk of serious health issues, including liver disease, cancer and cognitive decline.

Alcohol is also one of the key modifiable risk factors for dementia, but it’s not always front of mind when people think about brain health.

A program designed for older adults

The program, called Rethink My Drink, was developed by researchers at UNSW and the University of Sydney and designed specifically for older adults.

It includes four online modules that guide people through understanding their drinking habits, setting goals and making small, manageable changes.

The format is simple and private, and can be completed at home — without needing to see a clinician.

What the research found

The study involved 888 participants aged between 60 and 75 from across Australia.

After 12 months, those who completed the program reduced their alcohol consumption by an average of more than 36 drinks per month. Compared to those who only received general information, this worked out to around five fewer standard drinks per month.

That might not sound dramatic, but at a population level, even small reductions can have a meaningful impact on health over time.

What about brain health?

Researchers also looked at whether reducing alcohol could improve cognitive function.

Participants in the program did show improvements over time, but these were not significantly greater than those in the comparison group. Larger studies are needed to better understand the link.

Even so, the connection between alcohol use and dementia risk is well established, with alcohol use disorders linked to a significantly higher risk of developing dementia.

A simple way to make a change

One of the biggest advantages of the program is how accessible it is.

It was co-designed with older adults to make sure it is easy to use, relevant and practical. Because it is delivered online, it could be rolled out more widely, including in rural and regional areas.

For many people, cutting back on alcohol doesn’t require drastic change. It can start with small steps — and having the right support can make those changes easier to stick.
