Australians plan to be more frugal and trim down in 2025, but experts warn meaningful change will take sustained effort.
Comparison website Finder surveyed over 1000 people and found more than 50 per cent were planning to save more, while over a third of Australians had plans to lose weight.
Many have set financial goals including half who plan to save more, 30 per cent who hope to spend less and over 25 per cent who want to reduce expenses as households continue to grapple with cost-of-living pressures.
Almost 40 per cent of respondents said they wanted to eat healthier, while about a third said they wanted to improve fitness or lose weight.
However, Brain and Mind centre director Ian Hickie said most New Years resolutions were a waste of time because people are hardwired to enjoy pleasure.
"People underrate how difficult it is to achieve changes in their behaviour," he told AAP.
"All the short-term things we have are all pleasurable and fun and easy to do, and all the better things are hard, not much fun with not much enjoyment."
He said it's easy for someone to say they will eat better or give up drinking but the key to success is having groups of people who want to do it with them.
"When your individual motivation died out ... somebody else says, 'no, no, we're getting out of bed or we're going to the gym again'.
"Because if you try to do it alone, the evidence shows us you give up about two days in ... and they are back to where they were."
At least 20 per cent of Australians are planning to head overseas, and five per cent said they would move interstate or overseas in the year ahead.
Other resolutions included more rest, improving work-life balance and renovating the home.
Many Australians will prioritise their physical and mental wellbeing in the coming year, Finder's head of consumer research Graham Cooke said.
"Prioritising sleep and striving for a healthier work-life balance can significantly enhance productivity, performance and overall life satisfaction."
He said meaningful change would take time and reminded people to celebrate the small wins with consistent effort.
