In short
Moving from the top of the NSW classroom scale ($133,422) to head teacher or assistant principal ($153,531) adds $20,109 a year before tax but about $12,377 after tax, or roughly $476 a fortnight, on 2026–27 rates. If the role adds 200 hours a year, that's about $62 an hour after tax for the extra work.

Leadership pay by state, October 2026
Sources: state agreements and salary schedules, checked 16 October 2026. Victorian figures are the VGSA 2022 rates still in force; the VGSA 2026 lifts them once approved. Principal levels are set by school size or complexity.
Why a promotion is worth less than the headline
Two things shrink a leadership pay rise. The first is tax: most teachers already pay 32 cents in each extra dollar (30% plus Medicare), and above $135,000 the rate rises to 39%. Many promotions cross that line, so part of the rise is taxed at the higher rate. The second is HECS-HELP: under the 2026–27 system, repayments take 15 to 17 cents of each extra dollar of income until the top band, where the repayment becomes 10% of your whole income.

Things the calculator can't weigh for you
- Teaching load. Leaders usually teach less. NSW high school head teachers teach 22 periods a week and deputies 14, against 28 for classroom teachers. Fewer classes can offset some extra admin time.
- Super. Employer super is 12% of salary, so a $20,109 rise adds about $2,413 a year to your super. Over a decade that's meaningful.
- Long service leave and parental leave. These are paid at your salary, so they're worth more on a leadership salary.
- The alternative path. HALT certification can lift classroom pay without a leadership role: $141,997 for NSW HA/Lead teachers, $147,050 for Queensland Lead Teachers and a $29,184 allowance for NT Lead Teachers.
Deputy and principal: the bigger jumps
In NSW, deputy principal pays $179,255. That's $45,833 more than Step 7 before tax, and about $28,069 more after tax: $128,276 against $100,207. Most of the extra is taxed at 39%. Principal salaries in NSW run from $184,175 to $236,318, depending on the school's funding allocation.
