Where the 18 Year Old Minimum Wage Sits
The national full-time adult ordinary-time average, as measured by the ABS Average Weekly Earnings for May 2026, is $2083.70 a week, or about $108,352 a year. That is the line on this site. By contrast, the adult national minimum wage from Fair Work, effective 1 July 2026, is $26.44 an hour, $1004.90 a week, or about $52,255 a year on a 38-hour week. That is roughly half the average. But for an 18-year-old, the minimum wage is not a single figure. It depends on the award or enterprise agreement that applies to their job.
Junior Rates Under Awards
Under the Fair Work system, employees under 21 can be paid a junior rate, which is a percentage of the adult rate for the same classification. The percentage varies by age and by award. For an 18-year-old, common percentages range from 70% to 80% of the adult rate. For example, if the adult rate under a particular award is $26.44 an hour, an 18-year-old might receive between $18.51 and $21.15 an hour. That translates to a yearly salary of roughly $36,600 to $41,800 on a 38-hour week — well below the full-time average and even below the adult minimum wage.
Some awards set higher percentages for 18-year-olds, especially in trades or where the employee has completed a certain level of training. Others may have flat rates that are not strictly a percentage. The only way to know the exact rate is to check the specific award or enterprise agreement. The Fair Work Ombudsman provides a pay calculator and award summaries, but those are not replicated here.
How Far Below the Average?
To place a salary on the line, you can enter a yearly figure and see its distance from the national full-time average. For an 18-year-old on a typical junior rate of, say, $20 an hour, the yearly salary on 38 hours would be about $39,520. That is roughly $68,832 below the average — a gap of about 64%. Even if the 18-year-old works full-time hours, they are unlikely to reach the average until they turn 21 and move to the adult rate, or until they gain enough experience to qualify for higher classifications.
What Would Move Pay Above the Average?
Several factors can push an 18-year-old's earnings above the national average. The most obvious is age: once the employee turns 21, they become entitled to the adult rate under most awards, which immediately lifts their pay. But even before that, working in a high-paying industry can make a difference. For instance, the States and territories page shows that the full-time average in Western Australia is $115,825, driven by mining and resources. An 18-year-old in a mining traineeship might earn well above the national average, especially if overtime and allowances are included.
Penalty rates for evening, weekend, or public holiday work can also boost earnings significantly. Many retail and hospitality awards pay time-and-a-half or double time for unsocial hours. An 18-year-old who works regular weekend shifts could earn more than the adult minimum wage, and possibly approach the average if they work enough hours.
Another factor is skill level. Some awards have multiple pay levels based on competency. An 18-year-old who has completed a Certificate III or an apprenticeship may be entitled to a higher percentage or a higher classification. In trades like electrical or plumbing, junior rates can be 90% or more of the adult rate in the final year of training.
The Role of Enterprise Agreements
Some employers have enterprise agreements that set higher rates than the award. These agreements are negotiated between the employer and employees (or their union) and must pass the better-off-overall test. An 18-year-old covered by a generous enterprise agreement might earn close to or even above the adult minimum wage, though still below the full-time average in most cases.
Medians and Other Benchmarks
It is useful to compare the 18-year-old minimum wage not only to the average but also to medians. The ABS Employee earnings for August 2025 show a full-time median of about $90,532 and an all-employees median of about $74,100. Even the adult minimum wage is well below those medians. For an 18-year-old on a junior rate, the gap is even wider. The median is a better indicator of what a typical worker earns, while the average is pulled up by high earners.
Tax Implications
An 18-year-old earning a junior rate of around $40,000 a year would fall into the 15% tax bracket for 2026–27 (after the tax-free threshold of $18,200). The Medicare levy of 2% also applies. Their take-home pay would be roughly $34,000 after tax and levy, assuming no other deductions. That is a modest income, and it highlights how far below the average the junior minimum wage sits.
Conclusion
The 18 year old minimum wage is not a single number; it is a range determined by awards and agreements. In almost all cases, it is well below the national full-time average of $108,352. Factors that could move it closer to or above the average include turning 21, working in a high-paying industry, earning penalty rates, or being covered by a favourable enterprise agreement.
