Understanding ADF salary sacrifice
Salary sacrifice is a common feature of Australian workplace remuneration, and the Australian Defence Force (ADF) offers its members the ability to sacrifice part of their salary for certain benefits. This article explains how ADF salary sacrifice works, its tax implications, and how your take-home pay compares to the national full-time average.
How salary sacrifice works
Under a salary sacrifice arrangement, an ADF member agrees to reduce their gross salary in exchange for a benefit provided by their employer. Common benefits include additional superannuation contributions, a novated lease on a car, or other approved items such as laptops or childcare. The sacrificed amount is deducted from your salary before tax is calculated, which lowers your taxable income.
For ADF members, salary sacrifice is typically administered through the Defence Salary System and must comply with ATO guidelines. The benefit must be genuinely available to the employee and not a substitute for cash wages. It is important to note that salary sacrifice does not reduce your superannuation guarantee, which is calculated on your ordinary time earnings before sacrifice.
Tax implications using 2026–27 rates
The main advantage of salary sacrifice is the tax saving. By reducing your taxable income, you may move into a lower marginal tax bracket. For the 2026–27 financial year, the resident tax rates are:
- Nil on income up to $18,200
- 15% on income from $18,201 to $45,000
- 30% on income from $45,001 to $135,000
- 37% on income from $135,001 to $190,000
- 45% on income above $190,000
Plus the Medicare levy of 2% (before any reductions).
If you earn the national full-time average of $108,352, your marginal rate is 30% plus 2% Medicare levy. Sacrificing $10,000 would reduce your taxable income to $98,352, saving you $3,200 in tax and Medicare. However, you would also be paying for the benefit, so your actual take-home pay may be lower than if you had not sacrificed. The net benefit depends on the cost of the benefit and your personal circumstances.
Comparing to the national average
The site's line is the national full-time adult ordinary-time average of $108,352 per year, based on ABS Average Weekly Earnings for May 2026. This is the benchmark we use to show where your pay sits. ADF salary sacrifice can make your taxable income appear lower than this figure, but your total remuneration package (including the sacrificed benefit) may still be competitive.
For context, the full-time median is about $90,532, and the all-employees median is about $74,100 (ABS Employee Earnings, August 2025). The national minimum wage from 1 July 2026 is $26.44 per hour, or $52,255 per year on a 38-hour week. ADF members are paid above the minimum wage, with salaries set by the Defence Force Remuneration Tribunal.
State variations
ADF members may be posted across Australia, and state averages vary. The full-time averages by state are:
- New South Wales: $109,658
- Victoria: $106,137
- Queensland: $106,064
- South Australia: $102,450
- Western Australia: $115,825
- Tasmania: $96,008
- Northern Territory: $103,173
- Australian Capital Territory: $119,090
If you are posted to a state with a higher average, your salary may be below the local average, but salary sacrifice can help manage your tax position. Conversely, in lower-average states, your ADF pay may be above the local norm.
Other benchmarks
It is useful to compare your total remuneration package—including any salary-sacrificed benefits—against the national average. The site also provides job medians and industry medians for civilian roles. ADF roles are not directly covered by these categories, but you can use the Place a salary on the line tool to see where your package sits relative to the national full-time average.
Remember that salary sacrifice does not change your superannuation guarantee, which is 11.5% of your ordinary time earnings (as of 2026–27). Your employer must still pay this on your pre-sacrifice salary.
Conclusion
ADF salary sacrifice is a valuable way to reduce your taxable income and obtain benefits at a lower after-tax cost. While the ABS and Fair Work do not publish a specific figure for ADF salary sacrifice, you can use the national average of $108,352 as a reference point.
