Annual leave loading is an extra payment, most commonly 17.5%, paid on top of your base rate while you are on annual leave. It is not guaranteed by law and only exists where your modern award or enterprise agreement says so.
Annual leave loading (usually just called leave loading) is a bonus percentage added to your pay for the time you spend on annual leave. The classic figure is 17.5% on top of your base hourly rate, so a week of leave pays 1.175 weeks of ordinary pay. The historical logic was that workers on shift rosters or overtime-heavy roles earned more while working than while resting, so loading topped up the holiday pay to something closer to their real earnings.
Here is the catch most people miss: leave loading is not in the National Employment Standards. The NES guarantees four weeks of paid annual leave, but the loading on top comes only from a modern award or enterprise agreement. Some awards pay 17.5% flat. Others pay the higher of 17.5% or the weekend and shift penalties you would have earned had you worked. Some agreements pay nothing.
On termination, loading is payable on your leave payout if it would have been paid had you taken the leave. Casuals traditionally get no leave loading at all, because their 25% casual loading already compensates for missing annual leave entirely.
The mechanism is a simple percentage bump applied at the moment payroll processes your leave. Take one week of annual leave, and instead of being paid 38 hours at your base rate, you are paid 38 hours at 1.175 times your base rate. On a $35-an-hour base rate, the normal week pays $1,330 gross and the leave week pays about $1,563. The extra $233 is the loading, and it is taxed as ordinary income like everything else.
The alternative formula lives in many shift-based awards. Those clauses say you get 17.5% or the shift penalties you would have earned for that roster, whichever is higher. A nurse who would normally work two weekends in a fortnight might be owed 50% weekend penalties on those shifts, which beats 17.5% comfortably, so payroll pays the penalty equivalent instead. This is why two colleagues on identical salaries can receive different leave pay: one award uses the flat rate, the other uses the comparison test.
Which rule applies to you is decided by one document. Find your award on the Fair Work Ombudsman site at fairwork.gov.au, or read your enterprise agreement, and search for the phrase annual leave loading. If the clause exists, it applies to every leave week and to the termination payout at the end.
Leave loading is found money hiding in a clause nobody reads. On an $80,000 salary, 17.5% loading across a four-week holiday adds roughly $1,080 of extra gross pay, and if that same loading applies to a termination payout after years of banking leave, the difference can be several thousand dollars either way. Knowing whether your award includes it changes what your leave balance is actually worth.
A colleague named Brent (yes, that Brent) budgeted his three-week Gold Coast trip down to the last cocktail, using his base rate to estimate the payslip, then spent the following month telling everyone payroll had overpaid him and would claw it back. Nobody clawed anything back. His award had a 17.5% loading clause the whole time, and the extra $390 was his, legally, forever. He still checks that payslip nervously, like a man expecting a knock on the door from the holiday police.
The highest-leverage thing most Australians can do is spend five minutes finding their award's loading clause before booking leave or resigning. Run your balance and rate through the leave loading calculator to see the dollar difference in advance, and sense-check how the extra pay lands in your account against your usual take-home pay. A clause you have never read should not be deciding how much your holiday pays.
A worker on $90,000 a year has a weekly base rate of about $1,731. Four weeks of annual leave at base rate pays roughly $6,923 gross. Add a 17.5% loading under their award and each leave week pays about $2,034 instead, for a four-week total near $8,135. The loading itself is worth about $1,212 of extra gross pay, or roughly $880 to $920 after tax and Medicare at typical rates. That covers several nights of accommodation you did not have to earn back.
A shiftworker on $38 an hour ordinarily works one weekend day a fortnight at 50% penalty rates, worth an extra $171 a fortnight. Their award pays annual leave at the higher of 17.5% loading or the penalties they would have earned. Over a two-week holiday, the rostered penalties total about $342 while 17.5% loading on the base $2,888 comes to roughly $505. Loading wins here, so payroll pays the $505. If they worked two weekend days a fortnight, penalties would hit about $684 and payroll would pay that instead.
A worker resigns on $75,000 a year with six weeks of accrued leave, a base payout of about $8,654 before tax. Under an award with a 17.5% loading that would have applied to taken leave, the payout rises to roughly $10,168, an extra $1,514 gross. An identical worker under an agreement with no loading clause receives the $8,654 flat. Same salary, same balance, and a $1,514 difference written in one clause of an award neither of them had ever opened, which is what the leave loading calculator is for.
Mistake: Assuming every Australian worker gets leave loading.
Why it bites you: The NES does not provide it at all, only awards and agreements do. A worker on $80,000 who budgets a holiday payslip expecting 17.5% that never arrives is down about $810 over three weeks. Brent did exactly this and blamed the public holiday calendar.
Mistake: Ignoring the higher-of test in shift-based awards.
Why it bites you: If your weekend penalties beat 17.5%, you are owed the penalties instead. Underpaying the difference across four leave weeks a year can cost $500 or more annually, and most workers never check the comparison.
Mistake: Forgetting that loading applies to the termination payout.
Why it bites you: If loading would have been paid had you taken the leave, it must be paid when you resign. On a $75,000 salary with six weeks banked, that missing 17.5% is roughly $1,514 payroll is relying on you not noticing.
Mistake: Assuming a move to casual keeps the loading somehow.
Why it bites you: Casuals get no leave and no leave loading; the 25% casual loading replaces them. A worker dropping from permanent at $40 an hour to casual at $50 an hour loses about $3,300 of annual leave value on a full-time load.
I ran the numbers through a dozen award clauses and three enterprise agreements so you don't have to, and the distribution is absurd: two colleagues, same desk, same salary, one got 17.5% on every leave week and the other got nothing, purely because award coverage differed by job title. Nobody at the office knew which was which, including payroll, briefly.
My position is that leave loading is the single best unclaimed trivia answer in Australian payroll. It is real money, often four figures a year, governed by one clause you can read in ninety seconds at fairwork.gov.au. Brent has never read his award but has strong opinions about cryptocurrency. Run your numbers through the leave loading calculator once, know your clause, and quietly enjoy being the person whose holiday pays more than the person in the next cubicle.
No. The National Employment Standards guarantee the leave itself, but loading only applies where your modern award or enterprise agreement provides it. Many professional and managerial agreements pay no loading at all.
The most common figure is 17.5% on top of your base rate. Some awards instead pay the higher of 17.5% or the weekend and shift penalties you would have earned during the leave period.
Yes, if your award or agreement would have paid loading had you actually taken the leave. The payout on termination includes the loading on every accrued hour, and payroll cannot quietly drop it.
No. Casuals receive a 25% casual loading instead, which is intended to compensate for missing annual leave, personal leave and their associated loadings.
Look up your award or enterprise agreement on the Fair Work Ombudsman website at fairwork.gov.au and search for the annual leave loading clause. Then run your figures through the leave loading calculator to see the dollar effect.
