Every pay cycle, an employer decides what to pay each worker, and almost every one of those decisions starts from the same number: the base rate of pay.
The base rate is the minimum amount an employee must receive for their ordinary hours of work. It is the foundation of the pay system under the Fair Work Act, because penalty rates, overtime, allowances, leave payments and even parts of the superannuation calculation are all built on it. If the base rate is wrong, everything stacked on top of it is wrong too.
This guide explains how the base rate works in practice: what the law means by the term, where a rate comes from, how it applies to casual, part-time and salaried staff, and where employers most often get it wrong. If you run payroll for a small business, this is the area of employment law you touch most often.
What the law means by base rate of pay
The starting point is the definition in s 16 of the Fair Work Act 2009 (Cth). The base rate of pay is the rate payable to an employee for their ordinary hours of work, but it expressly excludes:
- Incentive-based payments and bonuses: commissions and performance payments are not part of the base rate.
- Loadings: casual loading, shift loading and similar additions sit outside it.
- Monetary allowances: payments for tools, travel, first aid duties or meals are separate.
- Overtime or penalty rates: the higher pay for extra hours or unsociable times is calculated on top of the base rate.
- Any other separately identifiable amounts: if a payment can be identified as a distinct component, it is not part of the base rate.
To see why the definition matters, consider what the Act pays at the base rate. Paid annual leave under s 90 and paid personal or carer's leave under s 99 are paid at the employee's base rate for their ordinary hours, and redundancy pay under s 119 is calculated the same way. An employee whose roster is full of penalty-heavy shifts still gets leave paid at the plain base rate, not at the loaded rate. The base rate is therefore not just a payroll input. It is the statutory measure for some of the most expensive entitlements an employer funds.
Where the base rate comes from
The system has three sources, and the first step with any role is working out which one applies. Most employees in Australia are covered by a modern award. If the business has a registered enterprise agreement that covers the role, the agreement applies instead. If neither applies, the employee is award/agreement free and the National Minimum Wage is the floor.
Three actors run this system, and it helps to know which does what:
- Fair Work Commission: sets award rates and the National Minimum Wage each year through the Annual Wage Review, and approves enterprise agreements.
- Fair Work Ombudsman: enforces the minimums, investigates underpayment, and publishes pay guides and the Pay and Conditions Tool that employers use to check rates.
- Employer: classifies the role, applies the correct rate, and keeps records that prove it.
Modern awards: classification first
Modern awards are industry or occupation instruments that set minimum pay and conditions. Each award contains classification levels with descriptions of the duties at each level, and each level carries its own hourly rate. The base rate for an employee is the ordinary hourly rate attached to the classification that matches their actual duties and responsibilities, not their job title. The Fair Work Ombudsman publishes a pay guide for every award that lists the rates for each classification, which is the fastest way to check a rate without reading the award itself.
Enterprise agreements: the floor stays
If the business has an enterprise agreement, its base rates replace the award rates for covered employees, but not without limits. Under s 206 of the Fair Work Act 2009 (Cth), the agreement's base rate must not be less than the award rate or the National Minimum Wage order rate that would otherwise apply. If it is lower, the agreement operates as if it matched the higher rate. On top of that, the Fair Work Commission must be satisfied that each award-covered employee would be better off overall under the agreement than under the award, a test set out in s 193. An agreement is not a way to reset pay below the safety net. It is a way to structure pay above it.
The National Minimum Wage: when nothing else applies
Where no award or agreement covers an employee, the National Minimum Wage applies. From 1 July 2026 it is $1,004.90 per week based on a week of 38 ordinary hours, or $26.44 per hour. The Fair Work Commission's Expert Panel reviews the rate each year, and the new rate applies from the first full pay period on or after 1 July. In the 2026 review, minimum award wages increased by 4.75%, with a floor requiring the lowest ongoing award rate to be at least the National Minimum Wage and entry-level rates in the first six months of employment to be at least $978.10 per week or $25.74 per hour.
The National Minimum Wage is set for adult employees, and separate special rates apply to juniors under 21 (a percentage of the adult rate by age), apprentices and trainees, and some employees with disability. Casual employees who are award/agreement free receive a 25% casual loading on top of the National Minimum Wage.
How the base rate applies to each employment type
Employment type changes how the base rate is expressed, not whether one exists.
Full-time and part-time employees
Full-time and part-time employees are both paid the base rate for their ordinary hours, which are typically 38 per week for full-time employees under the award or agreement. Part-time employees have agreed ordinary hours set out in writing, and the base rate applies to those hours. Hours worked beyond the agreed pattern can attract overtime, which is paid on top of the base rate.
Casual employees
Casual employees are paid a higher hourly rate instead of paid leave entitlements. Most awards express this as a 25% loading on the base rate, and many list a single casual rate that already includes it. The loading compensates for not accruing paid annual and personal leave, and it is separate from penalty rates, which can also apply to casual work on evenings, weekends or public holidays. When rostering, apply the award's rules for casuals, which can differ from the rules for permanent staff.
Salaried employees
Paying an annual salary does not remove the base rate. The salary must be high enough that the employee is not worse off than they would be under the award for their actual roster, including penalties, overtime and allowances. A number of modern awards include annualised salary clauses that permit a salary to cover those entitlements, but they typically require you to track hours and reconcile at set intervals, topping up the salary if it falls short of what the award would have produced. Where an award has no annualised salary clause, a salary cannot simply absorb award entitlements by assumption. Document the assumptions behind the salary and review them whenever the roster changes.
What sits on top of the base rate
Penalty rates, overtime and allowances are all calculated from the base rate, which is why the base rate itself has to be right first:
- Penalty rates: higher pay for work at particular times, such as evenings, weekends or public holidays, set by the award as a multiple or percentage of the base rate.
- Overtime: higher pay for work beyond ordinary hours or outside the award's span of hours, often time-and-a-half and double time.
- Allowances: fixed amounts added on top to cover particular requirements, such as tools, travel, first aid duties or meals.
Casual loading is different again, because it sits inside the base rate rather than on top of it. That is why the components need to be shown separately on the pay slip, and why it is worth testing a few typical rosters through payroll software before going live.
The base rate and superannuation
Superannuation is not calculated on the base rate, but on ordinary time earnings, which is closely related. Under s 6 of the Superannuation Guarantee (Administration) Act 1992 (Cth), ordinary time earnings means earnings for ordinary hours of work plus over-award payments, shift loading and commission. Overtime payments are not ordinary time earnings, and lump-sum payments on termination, such as unused leave payments, are excluded.
Two recent changes make this more than a background detail. The superannuation guarantee rate reached 12% on 1 July 2025, and from 1 July 2026 the new Payday Super rules require superannuation to be paid on each payday rather than quarterly, calculated on the employee's qualifying earnings. Getting the base rate and ordinary time earnings right is now part of every pay run, not an annual chore.
Where employers get it wrong
The recurring problems are consistent across small businesses, and they all trace back to the base rate:
- Wrong classification: choosing a level by job title rather than by the duties actually performed, so the base rate is too low.
- Missing the July update: rates change each year after the Annual Wage Review, and the new rates apply from the first full pay period on or after 1 July.
- Conflating casual loading with penalties: both can apply to the same shift, and the award dictates the interaction. Missing either one is an underpayment; applying both without checking is a possible overpayment.
- Salary set-off without reconciliation: assuming a salary covers award entitlements without tracking hours and comparing the outcome against the award minimums.
- Forgetting juniors, apprentices and trainees: separate rate tables and progression milestones, such as birthdays and apprenticeship stages, need calendar reminders.
- Hiding the components: a single blended figure on the pay slip makes leave payments and redundancy calculations harder to price, because they all use the base rate.
Records and pay slips: how the base rate is proved
The Fair Work Regulations 2009 (Cth) require employers to keep records of the rate of remuneration paid and, where a bonus, loading, penalty rate or allowance applies, the details of that payment. Pay slips must show the gross and net amounts and separately identify any bonus, loading, allowance, penalty rate or other separately identifiable entitlement. For hourly employees, the pay slip must state the ordinary hours rate and the number of hours paid at that rate.
In practice, this means the base rate should always be visible on the pay slip as its own line, with penalties, overtime and allowances listed separately. If a dispute or a Fair Work investigation ever happens, these records and pay slips are the evidence that the base rate was applied correctly, so they are worth treating as a compliance asset rather than an administrative chore.
When a lawyer helps
Most base rate questions can be answered from a pay guide, and the Fair Work Ombudsman's Pay and Conditions Tool is a reliable first check. But several situations justify professional help:
- Classification disputes: where duties sit across two levels or two awards, and the choice changes the rate.
- Enterprise agreements and annualised salaries: where the set-off structure, the better off overall test and the reconciliation rules need to be right from the start.
- After an underpayment complaint or audit: where exposure needs to be quantified across the workforce and a rectification plan agreed with the regulator.
- Multi-award businesses: where one workforce spans several instruments and the same role can fall under different awards depending on the site or task.
A lawyer's job at these points is usually to map the correct instrument and classification, check the maths against the award, and put the documentation in place so the rate survives scrutiny. Getting advice before payroll goes live is considerably cheaper than remediating a year of underpayments, which can involve back pay, interest and penalties.
Classification is the foundation, July is the trigger
The decision that drives everything else in this system is the first one: which award, if any, covers the role, and which classification level matches the duties. The base rate, the leave payments, the penalty calculations and the superannuation all follow from that choice. Once it is right, staying compliant is mechanical: update rates each July when the Annual Wage Review lands, keep the pay slip lines separate, and reconcile salaried employees against the award at the intervals it requires. If you are unsure about a classification or an annualised salary arrangement, a short consultation to confirm the structure is a small cost compared with the back pay, interest and penalties that flow from getting the foundation wrong.
