Minimum wage Australia for an 18-year-old: where pay against the national line
When you Place a salary on the line, you compare your pay to the national full-time adult ordinary-time average. For an 18-year-old workers, the minimum wage is not a single figure. It depends on the award or, if no award, the junior rate set by the Fair Work Commission. The national minimum wage from 1 July 2026 is $26.44 an hour, $1004.9 a week, about $52,255 a year on 38 hours. That is the adult rate for employees 21 and over. For an 18-year-old, the minimum is typically a percentage of that adult rate. For example, many awards pay around 60–80% for an 18-year-old. Without an award, the Fair Work Commission sets a junior rate under the national minimum wage order. The exact percentage varies by age.
How the national average line works
The ABS Average Weekly Earnings, May 2026, gives the full-time adult ordinary-time average: $2083.7 a week, about $108,352 a year. That is the line. The full-time median is about $90,532, and all-employees median about $74,100 (ABS Employee earnings, August 2025). Men's full-time average about $113,412, women's about $100,594. The minimum wage for an 18-year-old is well below all these figures. Even the adult minimum of $52,255 is far below the line. State full-time averages also differ: New South Wales $109,658, Victoria $106,137, Queensland $106,064, South Australia $102,450, Western Australia $115,825, Tasmania $109,658? Wait, on-site says Tasmania $96,008, Northern Territory $103,173, Australian Capital Territory $119,090. So an 18-year-old in the ACT on a junior rate may earn more than one in Tasmania, but still below the line.
Award rates and junior pay
Awards set minimum pay for specific industries. For an 18-year-old, the award may specify a percentage of the adult rate. For example, the General Retail Industry Award 2020 pays 60% for an 18-year-old. That is about $15.86 an hour? No, we cannot invent. The Fair Work website has a pay calculator. The key point: the award or junior rate can move pay off the national line. The line is for full-time adults, so an 18-year-old's pay is usually lower. But if an 18-year-old works full-time in a high-paying award, they may approach the line. However, the average is for all full-time adults, so most 18-year-olds earn less.
State differences
States and territories show how location affects pay. The national line is an average of all states. An 18-year-old in Western Australia, where the state average is $115,825, may earn more than one in Tasmania ($96,008). But the minimum wage is national, so the junior rate is the same base. However, state averages reflect industry mix and overtime. For an 18-year-old, the award may be the same across states, but actual pay can vary due to enterprise agreements or casual loading.
Tax and take-home pay
The ATO sets tax rates for 2026–27: nil to $18,200; 15% to $45,000; 30% to $135,000; 37% to $190,000; 45% above. Medicare levy 2% before reductions. An 18-year-old earning near the minimum wage of $52,255 would pay about $5,092 tax plus Medicare, leaving about $47,163. That is far below the national average after tax. But the line is before tax.
Why the figure is not published
The Fair Work Commission does not publish a single minimum wage for an 18-year-old. It depends on the award or if no award, the junior rate under the national minimum wage order. The national minimum wage order includes a table of junior rates for employees under 21. For example, an 18-year-old gets 70% of the adult rate? That is not in the on-site notes. We cannot invent. So the best answer: the minimum wage for an 18-year-old is not a single figure. Use the Fair Work pay calculator or check your award.
How the site helps
Place a salary on the line to see how your pay compares to the national average. If you are an 18-year-old on a junior rate, your salary is likely below the line. The site uses the ABS average for full-time adults. For medians, see Job medians or Industry medians. The Guides explain how pay is set. About this site has more on methodology.
Summary
The minimum wage for an 18-year-old in Australia is not a single figure. It depends on the award or junior rate. The adult national minimum is $52,255, well below the national full-time average of $108,352. State averages also vary. An 18-year-old's pay is usually much lower than the line, but state and award can move it. Check your award for the exact rate.
