On average, females in Australia currently retire with super account balances of approximately $112,600, Ms Young said.

“That’s much less than the amount a single woman needs for a $40,000 a year retirement income, which is at the lower end of the ‘what’s adequate’ scale,” she said.

“It’s never too late for women to start learning about all sorts of practical things they can do to make a difference to their super over time.

“It surprises a lot of people that putting the equivalent cost of one cup of coffee a day into your super can add up to an extra $128,000 when you retire,” Ms Young added.
