What is the typical hourly rate for an assistant principal in Australia?

Assistant principal salaries vary by state, sector, and experience. The Australian Bureau of Statistics reports average full-time adult ordinary time earnings of $2,083.70 per week (May 2026), which equates to about $54.83 per hour for a 38-hour week. Many assistant principals earn above this average, often under enterprise agreements rather than award rates.

How do I convert an assistant principal's hourly rate to an annual salary?

Multiply the hourly rate by the number of hours worked per week (typically 38 for full-time) and then by 52 weeks. For example, $55 per hour × 38 hours × 52 weeks = $108,680 per year. This assumes no unpaid overtime, penalty rates, or allowances. Use our [hourly conversion](/topics/hourly-conversion) tool for quick calculations.

What tax and superannuation apply to an assistant principal salary?

For 2026–27, resident tax rates are: nil up to $18,200, 15% from $18,201 to $45,000, 30% to $135,000, 37% to $190,000, and 45% above that. Medicare levy is generally 2%. Super guarantee is 12% of ordinary earnings, paid on top, up to the $270,830 maximum contribution base. See our [super and packaging](/topics/super-and-packaging) page for details.

Assistant Principal Salary: How to Convert Hourly Rates to Annual Pay in Australia

For a full-time assistant principal earning $54.83 per hour (based on ABS average weekly earnings), the annual salary would be approximately $108,400 before tax, assuming a 38-hour week and 52 weeks per year.

Understanding Assistant Principal Salary Calculations

When you're evaluating an assistant principal salary offer or comparing roles, converting an hourly rate to annual pay is a common first step. In Australia, full-time work is typically based on 38 ordinary hours per week, as set by the Fair Work Ombudsman and the Fair Work Commission. The formula is straightforward: multiply the hourly rate by 38, then by 52 weeks. This gives you the gross annual salary before tax and super.

For example, if an assistant principal earns $55 per hour, the annual figure would be $55 × 38 × 52 = $108,680. This assumes the same rate every week, no unpaid overtime, and no penalty rates or allowances. It's a useful benchmark, but actual pay may differ depending on the school's enterprise agreement or individual contract.

Award Rates and Assistant Principal Classifications

Assistant principals are typically senior teaching staff and are not covered by the Educational Services (Schools) General Staff Award 2020 (MA000076). That award covers general staff such as administration, catering, and maintenance. However, it provides a useful reference for pay structures. The award's highest classification, Level 8, has an annual salary of $92,479 for a full-time employee working 38 hours per week, which equates to $46.64 per hour. This is significantly lower than typical assistant principal salaries, which often exceed $100,000 per year.

For teaching and leadership roles, separate awards or enterprise agreements apply. The Fair Work Ombudsman's page for the general staff award notes that "principal" means the most senior leadership position, but assistant principals are usually classified under the School Education Employees' Award or state-based agreements. Always check the specific award or agreement that covers your role.

National Minimum Wage and Casual Loading

The national minimum wage from 1 July 2026 is $26.44 per hour, or $1,004.90 per week for 38 hours, as set by the Fair Work Commission. This is the floor for award/agreement-free employees. Assistant principals earn well above this. For casual employees, a 25% loading applies, bringing the casual minimum to $33.05 per hour. However, assistant principals are almost always permanent full-time or part-time, so casual loading is not relevant to their salary calculations.

Fortnightly Pay and Budgeting

Many schools pay fortnightly. To find your fortnightly gross pay, multiply the weekly rate by 2. For an assistant principal earning $2,083.70 per week (the ABS average for full-time adults), the fortnightly amount would be $4,167.40 before tax. This can help with budgeting and comparing job offers. Our pay guides page includes links to official award summaries.

Tax and Superannuation for Assistant Principals

For the 2026–27 financial year, resident tax rates are:

Nil on the first $18,200
15% on income from $18,201 to $45,000
30% on income from $45,001 to $135,000
37% on income from $135,001 to $190,000
45% on income above $190,000

Medicare levy is generally 2% of taxable income, with reductions for lower incomes. Superannuation guarantee is 12% of ordinary earnings, paid on top of your salary, up to the maximum contribution base of $270,830. For an assistant principal earning $108,400, the employer would contribute an additional $13,008 per year to super, subject to the cap.
