NSLHD Health Promotion director Paul Klarenaar said receiving the seasonal flu shot and keeping active are the best way for older adults to stay on their feet as we enter the cooler months.
Mr Klarenaar said even a small amount of extra physical activity leads to a big improvement in how well our immune system works.
"This becomes especially important as we get older," he said.
"The classes we provide are structured to make sure that you don’t just feel energised afterwards, but your muscles and bones get stronger as well."
Thousands of people are now taking part in local groups each week to stay healthy with age.
Mr Klarenaar said classes were run in line with school terms, with registrations now open for Term Two which begins on April 24. The cost for most courses is $110, per term, with a concession rate of $88 available for eligible card holders.
