$21 an Hour Is Below the Adult Minimum Wage
$21 an hour is $5.44 under the $26.44 national minimum wage that an adult (21 or older) in the national system must be paid from 1 July 2026 (Annual Wage Review 2026). For an adult it is an underpayment unless it is one of these:
- A junior rate. The national junior scale sets $18.06 at age 18 and $21.82 at 19, so $21 meets the minimum for employees aged 18 and under (minimum wage at 18). Awards set their own junior percentages.
- An apprentice rate. Apprentice award minimums within 50c of $21:
- $21.13: 2nd-year junior apprentice, Year 12 completed (Electrical (apprentice electrician))
- $21.20: 2nd-year junior apprentice, Year 12 completed (Plumbing and mechanical services)
- Not an adult award rate. It is under every adult award minimum we track; the lowest is $25.74 (Fitness Industry Award, Level 1).
$41,496 a year is ahead of 3–4% of full-time employees (ABS Employee Earnings, August 2025) and $66,856 below the average full-time salary of $108,352 (May 2026).

Dropping to 25 hours a week cuts gross pay by 34% but take-home by only 29%, because the tax-free threshold and the Low Income Tax Offset cover a bigger share of the smaller income (both sit in the 15% bracket): you keep $20.49 of each hour, against $19.06 full time. The 30% rate starts above $45,000, $22.77 an hour full time. Every threshold at this income: take-home pay on $40,000.
