Australia’s superannuation system was designed to give everyone a dignified retirement. But for millions of Australian women, it compounds a lifetime of inequality — turning a pay gap into a retirement crisis.

Chart 1 of 5 — The Gap Right Now

By the time she’s 55, she’s already $62,000 behind

Most Australians assume superannuation is fair: everyone gets the same 11.5% on every dollar earned. But the gap between men’s and women’s super balances grows silently throughout a career. By the peak earning years of 55–59, the median woman has $140,662 in super — while the median man has $202,583. That’s a gap of $61,921. Hover over any bar to see exact balances.

Chart 2 of 5 — Ten Years of Evidence

The gap has grown every single year since 2012

This isn’t a new problem. The gender super gap has widened in nine of the last ten years. In 2012–13, the median woman had $9,593 less in super than the median man. By 2022–23, that gap had grown to $14,219. Select either line to isolate it, or hover for exact values.

Chart 3 of 5 — The Part-Time Penalty

Women work part-time far more than men — in every industry

Part-time work is the engine of the super gap. When you work part-time, you earn less, contribute less to super, and miss out on years of compounding growth. The data shows that in every single industry, women are significantly more likely to work part-time than men. The gap is largest in Other Services (+30.9 pp) and Education & Training (+22.5 pp).

Why does part-time work matter for super? A woman working 3 days a week instead of 5 earns 40% less — and gets 40% less in super contributions. Multiply that over 20 years of caregiving responsibilities, and you have a structural retirement disadvantage built into the system.

Chart 4 of 5 — The Income–Super Link

Lower pay today means lower super tomorrow — and women have always earned less

Super is a percentage of your wage. So if women consistently earn less than men, their super will always lag. This chart tracks both the income gap and the super gap over a decade. Use the buttons below to toggle between the two views and see how closely the gaps track each other.

Chart 5 of 5 — The Reform Question

The July 2025 reform helps — but won’t close the gap until the 2050s

From 1 July 2025, superannuation is paid on government-funded Paid Parental Leave (PPL). This is a landmark reform. But how much will it actually close the gap? Based on modelling using historical growth rates and the PPL super boost (~$2,300 per child), the gap narrows — but full parity at retirement age isn’t reached until the early 2050s. Use the dropdown to explore different scenarios.

The bottom line

Australia’s superannuation gap is not an accident. It is the predictable outcome of a system built around continuous, full-time employment — in a society where women still shoulder the majority of caregiving responsibilities.

The data tells a clear story:

This is not just a women’s issue. It is a policy failure that will cost Australian taxpayers as more women rely on the Age Pension in retirement. The question isn’t whether we can afford to fix it. It’s whether we can afford not to.
