How the Gender Pay Gap Affects Superannuation in Australia

Australia’s gender pay gap — the difference between average earnings of men and women — has a direct and compounding impact on superannuation. Because the Super Guarantee is a percentage of earnings, every pay gap dollar means a smaller super contribution — and that smaller contribution fails to compound over decades.


Australia’s Gender Pay Gap

According to the Workplace Gender Equality Agency (WGEA):

  • The total remuneration gender pay gap is approximately 22% (all employees)
  • The base salary gender pay gap is approximately 14%
  • Women’s average total remuneration: ~$91,000/year
  • Men’s average total remuneration: ~$118,000/year
  • Gap: ~$27,000/year

This gap arises from a combination of factors: occupational segregation, part-time work, promotion barriers, and the “motherhood penalty.”


How the Pay Gap Flows Into Super

The SG is 11.5% of ordinary time earnings in FY2024–25. A pay gap translates dollar-for-dollar (multiplied) into a super contribution gap:

Annual salarySG (11.5%)Super per year
$118,000 (man, average)11.5%$13,570
$91,000 (woman, average)11.5%$10,465
Annual super gap$3,105

The Compounding Effect Over a Career

The contribution gap is only part of the story — the investment compounding on the missing contributions is the larger issue:

Over a 30-year career (contributions starting at age 30):

  • Annual super gap: $3,105
  • Annual compounding (assumption: 7% average return)
  • Total shortfall due to pay gap alone by age 60: ~$290,000

Even if the pay gap were halved to 11%, the super shortfall by retirement would still exceed $145,000.


Industry and Occupation Pay Gaps

The pay gap varies by industry and occupation:

Industry (WGEA data)Pay gap (approx.)
Finance and insurance24%
Professional services19%
Healthcare16%
Education and training11%
Retail trade11%

Industries with higher pay gaps generate larger super shortfalls for women within those sectors.


Why the Pay Gap Persists

  • Occupational segregation: Female-dominated occupations (care, education, admin) are paid less than male-dominated occupations of comparable skill
  • Part-time penalty: Women more often work part-time (often involuntarily due to caring responsibilities), which typically precludes access to senior roles
  • Negotiation gap: Research shows women are less likely to negotiate salary, and less rewarded when they do
  • Promotion barriers: Women face slower career progression in many industries

Policy Actions

Mandatory gender pay gap reporting: From February 2024, WGEA began publicly publishing employer-level gender pay gap data for organisations with 100+ employees. This transparency is expected to accelerate pay gap closure.

SG on parental leave: From 1 July 2025, the government Parental Leave Pay scheme will include SG — partly addressing the career break contribution gap.
