In short
Higher duties pay is usually the difference between your salary and the higher role's salary, for the days you act. A NSW Step 7 teacher ($133,422) relieving as Head Teacher ($153,531) for a 10-week term earns about $3,867 extra before tax, or about $2,469 after tax, because part of it is taxed at 39%.
How to use the higher duties pay calculator
- 1
Pick your state and substantive step
Your substantive step is the salary you're normally paid. The calculator starts on the top classroom step, where most relieving leaders sit.
- 2
Choose the role you're acting in
Pick the leadership role from your state's data, such as Head Teacher, Assistant Principal or Deputy Principal. If your higher duties approval names a different rate, switch on the option to enter the salary yourself.
- 3
Set how long you'll act
Measure the period in weeks or days. A term is about 10 weeks, or 50 working days.
- 4
Read the extra pay
See the gross extra, what you keep after tax, the extra per fortnight while acting and the extra employer super. The table shows the same for a week up to a school year.
How higher duties pay is calculated
When you act in a higher position, most agreements pay you the higher role's salary, or the difference between the two, for the time you act. The calculator works it out as (higher salary − your salary) × days acting ÷ 260 working days. In the ACT, for example, the teaching staff agreement sets the higher duties allowance as the difference to the higher classification.

Why only 64%? Step 7 pays $133,422, just under the $135,000 threshold where the tax rate rises from 30% to 37%. The first $1,578 of extra pay is taxed at 32% including Medicare, and the rest at 39%. Teachers lower on the scale keep about 68 cents in the dollar. That's the same effect you'll see in the promotion pay calculator when you move up permanently.
The rules that change what you're paid
Higher duties rules are set by each state's agreement or award and by departmental policy, and they differ more than the pay itself. Before you start acting, check these with payroll or your union:
Ask before you start relieving
- Is there a minimum period before higher duties is paid? Many agreements need you to act continuously for a set time, often around a week and sometimes longer.
- Which point of the higher role's range applies? Some pay the bottom of the range, not the middle or top.
- Do you take on all the duties or only some? Part of the duties can mean part of the allowance.
- Are school holidays during the relieving period paid at the higher rate?
- Is the allowance counted as salary for super? This matters most in defined-benefit schemes.
- Will the acting time count as experience if you apply for the job permanently?
Is acting in a higher role worth it?
