Base salary explained: gross pay, super, and tax in Australia
Understand base salary in Australia: how it relates to gross pay, superannuation, and tax, with salary index benchmarks from ABS and Fair Work data.
Base salary is the fixed gross pay before super and bonuses; the national minimum wage base is $52,255 (index 48.2), while the full-time adult average is $108,352 (index 100).
What is base salary?
Base salary is the fixed gross amount an employer agrees to pay you for your work, before any additions like superannuation, bonuses, commissions, or overtime. In Australia, the term is closely related to the 'base rate of pay' defined under the Fair Work Act 2009. This rate cannot be less than the minimum wage set by a modern award or, if no award applies, the national minimum wage. The Fair Work Commission explains that if an enterprise agreement offers a base rate lower than the relevant award, the award rate prevails. So your base salary is the legal floor for your ordinary hours.
Base salary and the salary index
The Salary Index uses full-time adult ordinary time earnings as the national line (index 100). According to the Australian Bureau of Statistics' Average Weekly Earnings survey for May 2026, that figure is $2,083.70 per week, annualised to $108,352. Your base salary can be compared to this benchmark. For example, the national minimum wage from 1 July 2026 is $26.44 per hour, or $1,004.90 per week, annualised to $52,255. That gives an index of 48.2 – meaning it is about half the national average. A base salary of $80,000 would have an index of 73.8, while $120,000 would be 110.8. These comparisons help you see where your pay sits against the broader market.
Base salary, super, and tax
Your base salary is the starting point for two key calculations: superannuation and income tax. From 1 July 2026, the super guarantee is 12% of your ordinary time earnings, up to the maximum contribution base of $100,000 per year. So if your base salary is $100,000, your employer must contribute $12,000 into your super fund. This is on top of your base salary – it is not deducted from your pay. For tax, the Australian Tax Office applies the resident tax rates for 2026–27: no tax on the first $18,200, then 15% up to $45,000, 30% up to $135,000, 37% up to $190,000, and 45% above that. A 2% Medicare levy also applies. For example, a base salary of $80,000 would have an estimated tax of about $16,467 plus Medicare $1,600, leaving around $61,933 take-home. These figures ignore HELP repayments, salary sacrifice, and the Medicare levy surcharge.
How to find your base salary benchmark
To know if your base salary is fair, start with the relevant modern award or enterprise agreement. The Fair Work Ombudsman provides pay guides that list minimum base rates for each classification. For example, the minimum award wage for a retail employee (Level 1) is higher than the national minimum wage. You can also compare by industry: the ABS data shows mining has an average index of 154.7, while accommodation and food services is 72.5. State differences matter too – Western Australia averages index 106.9, while Tasmania is 88.6. Use the states and industries pages to see how your base salary stacks up.
Base salary vs total remuneration
It is common to see job ads quoting a 'total package' that includes super. But your base salary is the core figure for comparing roles. For example, a job offering $90,000 base plus 12% super ($10,800) has a total package of $100,800. Another job offering $100,000 base with the same super has a total package of $112,000. The base salary difference is $10,000, which affects your tax and borrowing power. Always clarify whether the figure quoted is base salary or total package.
The role of awards and enterprise agreements
Modern awards set minimum base rates for specific industries and occupations. These rates are reviewed annually by the Fair Work Commission. From 1 July 2026, award minimum wages increased by 4.75%. If you are covered by an award, your base salary cannot be less than the award rate for your classification. Enterprise agreements can set higher base rates, but never lower than the award. The topics page covers more on how these instruments affect your pay.
Base salary and junior rates
If you are under 21, your base salary may be a percentage of the adult national minimum wage. For example, a 16-year-old's minimum hourly rate is $12.51 (based on the national minimum wage of $26.44). However, some awards set different junior rates. Always check the applicable award or the Fair Work Ombudsman's Pay Calculator.
Final thoughts
Base salary is the foundation of your pay. Understanding it helps you negotiate, budget, and compare roles. Use the Salary Index to see where your base salary sits against the national line, and remember that super and tax are calculated on this figure. For specific role benchmarks, refer to pay guides and industry data.
Questions people ask
What is the difference between base salary and total package?
Base salary is the fixed gross amount an employee receives before any additions like superannuation, bonuses, commissions, or overtime. Total package (or total remuneration) includes base salary plus employer super contributions (currently 12%), and sometimes other benefits like a car or health insurance. For example, a base salary of $80,000 plus 12% super ($9,600) gives a total package of $89,600. The salary index uses gross base salary (or ordinary time earnings) for comparison.
How is super calculated on base salary?
Super guarantee is calculated on an employee's ordinary time earnings, which includes base salary but generally excludes overtime. From 1 July 2026, the rate is 12% of these earnings, up to the maximum contribution base of $270,830 per year. So if your base salary is $100,000, your employer must contribute $12,000 into your super fund annually. This is on top of your base salary and is not deducted from it.
How does tax apply to base salary?
Tax is applied to your gross base salary (plus any other income) using the resident tax rates for 2026–27: no tax on the first $18,200, then 15% up to $45,000, 30% up to $135,000, 37% up to $190,000, and 45% above that. A 2% Medicare levy also applies. For example, a base salary of $80,000 would have an estimated tax of about $16,467 plus Medicare $1,600, leaving around $61,933 take-home. This ignores the tax-free threshold, HELP, and other adjustments.
