Australians aged 30 and over are being urged to practice standing on one leg.

Neuroscience Research Australia senior principal research scientist Professor Kim Delbaere says the practice improves balance and offers other long-term health benefits, while preventing older Australians from debilitating falls.

"As our population ages, we'll have more people fall," she told Gary Adshead on 6PR Mornings.

"The single most effective strategy to prevent falls is practicing balancing.

"There are definitely other exercises we can do as well but we need to make sure we have all these initiatives and prevention strategies available to all Australians."
