Minimum wage Australia 20 year old: what you earn in 2026–27

What is the minimum wage for a 20-year-old in Australia?

If you are 20 years old and working in Australia, the national minimum wage sets a floor for what you must be paid. From 1 July 2026, the junior national minimum wage for a 20-year-old is $25.83 per hour. That works out to about $981.54 per week if you work a standard 38-hour week, or roughly $51,040 a year before tax.

This rate is not the same as the adult national minimum wage ($26.44 per hour). It is calculated using the percentages set out in the National Minimum Wage Orders, which apply a discount for age. For a 20-year-old, that discount is small – you earn about 97.7% of the adult rate. The idea is that younger workers may have less experience, but the gap narrows as you approach 21, when you generally become entitled to the full adult rate.

Where does this sit on the salary index?

The Salary Index measures gross yearly pay against the national line of 100, which represents full-time adult ordinary-time earnings ($108,352 a year based on ABS Average Weekly Earnings, May 2026). The adult national minimum wage has an index of 48.2. For a 20-year-old on the junior minimum, the index is roughly 47.1 – meaning you earn about 47% of the national benchmark. That is a little below the adult NMW index, reflecting the junior discount.

Keep in mind that the index is a benchmark, not a quote for your specific job. Your actual pay may be higher if you work in an industry with a higher award rate, or if your employer pays above the minimum.

How awards and agreements affect your pay

Many 20-year-olds are covered by a modern award, which sets minimum pay rates for a particular industry or occupation. Awards can have their own junior rates, and they may be different from the national junior minimum. For example, the Retail Award might set a higher hourly rate for a 20-year-old sales assistant than the national floor. Always check the pay guides for your award to see the exact rate.

If you are covered by an enterprise agreement, that agreement may also set a higher rate. The national minimum wage is the absolute floor – you cannot be paid less, but you can be paid more.

Casual loading and superannuation

If you are a casual employee, you are entitled to a casual loading – typically 25% on top of the base rate. For a 20-year-old on the junior minimum, that would be $32.29 per hour. That loading is meant to compensate for not receiving paid leave.

Superannuation is also part of your total remuneration. From 1 July 2026, the super guarantee is 12% of your ordinary-time earnings, paid by your employer into a super fund. On $51,040 a year, that adds about $6,125 in super contributions (before tax).

State and industry differences

Your pay relative to the national line can vary depending on where you live and what industry you work in. The states page shows how each state's average earnings compare. For example, Western Australia has an index of 106.9, meaning average earnings are above the national line, while Tasmania is at 88.6. If you are a 20-year-old in WA, you might find that award rates in mining or construction are well above the junior minimum.

Similarly, industries like retail trade (index 75.9) and accommodation and food services (72.5) tend to have lower average earnings, so the junior minimum may be closer to the typical pay in those sectors. In contrast, professional services (114.7) or mining (154.7) pay much more.

Tax and take-home pay

Your take-home pay depends on your total income and the tax rates for 2026–27. For a 20-year-old earning the junior minimum of $51,040, the estimated tax (including the 2% Medicare levy) would be:

• $0 on the first $18,200
• 15% on the next $26,800 ($4,020)
• 30% on the remaining $6,040 ($1,812)
• Plus Medicare levy 2% of $51,040 ($1,020.80)

Total tax and Medicare: about $6,852.80, leaving a take-home of roughly $44,187 per year, or $849.75 per week. This estimate ignores HELP repayments, salary sacrifice, or the Medicare levy surcharge.

When do you move to the adult rate?

Once you turn 21, you are generally entitled to the full adult national minimum wage ($26.44 per hour). Some awards may have a different progression – for example, you might move to the adult rate at 20 if you have completed a certain level of training. Check your award or agreement for details.

If you are an apprentice, your wage is set by a separate training wage schedule, which may be lower than the junior minimum. But apprentices also receive structured training and often progress to higher rates as they complete stages.

Key takeaways

• The minimum wage for a 20-year-old in Australia is $25.83 per hour under the national junior rate.
• This is about 97.7% of the adult national minimum wage and sits at an index of roughly 47.1.
• Awards and agreements can set higher rates, so always check your specific pay guides or contact the Fair Work Ombudsman.
• Casual loading, super, and tax all affect your actual take-home pay.
• Once you turn 21, you generally move to the adult rate unless your award says otherwise.
