How salary sacrifice superannuation employer obligations affect your pay
Salary sacrifice for superannuation is an arrangement where you agree to forgo part of your pre-tax salary in exchange for your employer contributing that amount to your super fund. This reduces your taxable income, but it does not change the gross salary figure that appears on your payslip or that is used to calculate the national full-time average.
The national full-time average is $108,352 a year ($2,083.70 a week) based on ABS Average Weekly Earnings, May 2026. This figure represents ordinary-time earnings before any deductions, including salary sacrifice. So if you salary sacrifice $10,000 a year, your gross salary is still $108,352 (if that is your pay), but your taxable income becomes $98,352. The line on this site compares your gross salary to the national average, not your net or taxable income.
Employer obligations under salary sacrifice
Employers have specific obligations when offering salary sacrifice for superannuation. They must:
- Ensure the arrangement is voluntary and documented in writing.
- Pay the Super Guarantee (currently 11.5% of ordinary-time earnings) on the sacrificed amount, because it remains part of your ordinary-time earnings.
- Not allow the sacrifice to reduce your base pay below the relevant minimum wage or award rate. The national minimum wage from 1 July 2026 is $26.44 per hour, $1,004.90 per week, or about $52,255 per year on a 38-hour week. Award minimums rose by 4.75% from that date.
- Comply with any award-specific rules. Some awards limit salary sacrifice to certain benefits or require employer consent.
These obligations mean that salary sacrifice is most common for employees earning above the minimum, often in higher-paying industries or roles.
Why a state or an award can move the figure off the national line
The national full-time average is a single number, but your pay can differ because of where you live or which award covers you. State averages vary significantly. For example, the Australian Capital Territory has a full-time average of $119,090, while Tasmania is $96,008. These differences reflect industry mix, cost of living, and the types of jobs available.
Salary sacrifice is more prevalent in some states and industries. In Western Australia, where the full-time average is $115,825, the mining and resources sector often uses salary sacrifice for super. In the public sector, common in the ACT, salary sacrifice for super is also widespread. This can affect the gross salary figures reported, but because salary sacrifice does not change gross pay, the state averages already include any sacrificed amounts.
Award coverage also plays a role. If you are covered by an award that restricts salary sacrifice, you may have less ability to reduce your taxable income. Conversely, if you are on an enterprise agreement or individual contract, you may have more flexibility. The minimum wage and award rates set a floor: your cash pay after sacrifice cannot fall below that floor. This means salary sacrifice is less common for workers near the minimum.
Comparing your salary to the line
When you place a salary on the line, the site shows how your gross yearly salary compares to the national full-time average. If you salary sacrifice, enter your gross salary before sacrifice. The site will then show your weekly and hourly equivalents on a 38-hour week, and the distance from the line. Your net take-home pay will be lower due to the sacrifice, but the line comparison is based on gross earnings.
For a fuller picture, you can also look at states and territories to see how your state's average compares, or how the figures are set to understand the sources. The national average is from ABS Average Weekly Earnings, May 2026. The full-time median is $90,532 and the all-employees median is $74,100 (ABS Employee Earnings, August 2025). These medians give a sense of typical earnings, while the average is pulled higher by top earners.
Tax implications of salary sacrifice
Salary sacrifice reduces your taxable income, which can lower the tax you pay. The 2026–27 resident tax rates are: nil up to $18,200; 15% from $18,201 to $45,000; 30% from $45,001 to $135,000; 37% from $135,001 to $190,000; and 45% above $190,000. The Medicare levy of 2% applies before any reductions. By sacrificing into super, you pay only 15% tax on contributions (up to the concessional cap), which can be less than your marginal rate.
However, employer obligations mean the sacrifice cannot reduce your pay below the minimum. And if you are on an award, check whether it allows salary sacrifice. Some awards require the employer to agree, and others specify that salary sacrifice cannot apply to penalty rates or overtime.
Summary
Salary sacrifice superannuation is a legitimate way to boost your retirement savings while reducing tax, but it does not change the gross salary figure used for the national average. Your state and award can affect how much you can sacrifice and whether your pay sits above or below the line. The national full-time average of $108,352 is a benchmark; your actual pay may differ due to location, industry, and award conditions. Use the tools on this site to see where you stand.
