Penalty rates are one of the most misunderstood aspects of Australian employment law—and one of the most expensive to get wrong. When you're building rosters, every shift you allocate during evenings, weekends, or public holidays triggers additional pay obligations under Fair Work. Understanding how rostering penalty rates work isn't just about compliance—it's about building rosters that balance staff coverage with labour costs. Modern employee rostering software can calculate these rates automatically, but you still need to understand the fundamentals.
This guide breaks down how penalty rates work across different awards, when they apply, and how to roster effectively while supporting compliance efforts. Whether you're running a hospitality venue with weekend trade, a retail store open on public holidays, or a healthcare facility with 24/7 coverage, these principles apply.
Quick summary
- Penalty rates range from 115% to 275% of base pay depending on time and day
- Weekend and public holiday rates vary significantly by industry award
- Casual employees receive penalty rates on top of their casual loading
- Underpaying penalties can result in significant back-pay and Fair Work fines

What are penalty rates and why do they exist?
Penalty rates are additional payments above the ordinary hourly rate that compensate employees for working during times when most people are off—evenings, weekends, and public holidays. The rationale is that employees sacrifice personal and family time during these periods, so higher pay compensates for that sacrifice.
Under Australian modern awards, penalty rates are not optional. If your employees are covered by an award (which most are), you must pay the applicable penalties when shifts fall during penalty periods. The rates vary by:
- Industry award: Hospitality, retail, healthcare, and other industries have different penalty structures
- Day of week: Saturday rates differ from Sunday rates, which differ from public holiday rates
- Time of day: Evening and night shifts often attract additional penalties
- Employment type: Casual employees receive penalties on top of their casual loading
Common penalty rate structures by industry
While each award has specific provisions, here are typical penalty rate structures across common industries. Always verify against the specific award that covers your employees, as rates change periodically.
| Day/Time | Hospitality | Retail | Healthcare |
|---|---|---|---|
| Saturday | 125% | 125% | 150% |
| Sunday | 150% | 150% | 175% |
| Public Holiday | 250% | 250% | 250% |
| Evening (after 7pm) | 115% | 125% | 115% |
Note: These are indicative rates for permanent employees. Actual rates vary by award, classification level, and employment type. Casual loadings apply in addition to these rates.
Common rostering mistakes with penalty rates
Understanding where businesses commonly go wrong helps you avoid the same pitfalls:
Applying wrong award rates
Using hospitality rates for retail workers or vice versa. Each award has specific penalty structures that must be applied correctly.
Forgetting casual loading stacks
Not applying penalty rates on top of casual loading. Casual weekend and public holiday rates are significantly higher than permanent rates.
Missing evening penalties
Many awards have evening penalty rates that start at 7pm or later. These are often overlooked but can add up across a workforce.
Public holiday calculation errors
Not accounting for state-specific public holidays or applying the wrong rate when shifts span multiple penalty periods.
Ignoring classification levels
Penalty percentages apply to the base rate for each classification. A Level 4 employee's penalty payment is higher than a Level 1 in absolute terms.
Manual calculation errors
Spreadsheet-based rostering is prone to formula errors, especially when shifts cross penalty rate boundaries at midnight or other trigger times. Consider using a free roster builder to reduce manual errors.
Strategic rostering around penalty rates
While you must pay correct penalty rates, smart rostering can help manage costs without compromising coverage or compliance:
Understand your demand patterns
Analyse when you actually need staff versus when you traditionally roster them. If Sunday lunch is slow, you might not need full weekend staffing levels. Match staffing to actual demand using rostering analytics.
Balance penalty shifts fairly
Distribute weekend and public holiday shifts across your team. Some staff prefer these shifts for the extra pay; others value their weekends. Fair distribution improves morale and reduces turnover.
Consider shift start and end times
If evening penalties kick in at 7pm, a shift ending at 6:45pm avoids them entirely. Small adjustments to shift times can have significant cost impacts across a roster.
Use real-time cost visibility
Build rosters with software that shows labour costs in real-time as you allocate shifts. This helps you make informed decisions about staffing levels during penalty periods. Connect this to payroll integration for accurate forecasting.
Plan for public holidays in advance
Public holidays are the most expensive rostering days. Plan rosters well ahead, consider minimum staffing levels, and factor the cost into pricing if you're in hospitality or retail.
Penalty rates for casuals vs permanent employees
One of the most common sources of underpayment is miscalculating casual penalty rates. The casual loading (typically 25%) is applied first, then penalty rates are calculated on top:
- Permanent Sunday rate (150%): $25 base × 150% = $37.50 per hour
- Casual Sunday rate: $25 base × 125% casual loading = $31.25, then × 150% = $46.88 per hour
This stacking effect means casual employees working weekends and public holidays cost significantly more than permanent staff. For businesses with high weekend trade, the mix of casual versus permanent staff has major cost implications.
Many businesses find that converting reliable casuals to part-time permanent roles actually reduces weekend labour costs, even accounting for leave entitlements. Use your time and attendance data to identify casuals who work consistent hours and might benefit from permanent arrangements.
How rostering software handles penalty rates
Modern rostering platforms with Australian award interpretation eliminate most penalty rate calculation errors:
Automatic rate calculation
Penalty rates apply automatically based on shift timing, day of week, and employee award classification.
Real-time cost visibility
See total labour costs as you build rosters, with penalties calculated and displayed in real-time.
Award rate tracking
Configure award rates in your system to calculate penalties correctly. When Fair Work updates rates (typically July each year), update your settings accordingly.
Employee classification tracking
Each employee's award, classification level, and employment type is stored, ensuring correct rates apply every time.
Payroll-ready exports
Timesheet data exports to payroll systems with penalty rates already calculated and coded correctly.
Public holiday alerts
Automatic reminders when you're rostering on public holidays, with state-specific holiday calendars built in.
Consequences of penalty rate underpayments
The risks of getting penalty rates wrong are significant:
- Back-pay liability: Claims can go back six years. A $5 per hour underpayment on weekend shifts across multiple employees quickly becomes tens of thousands of dollars.
- Fair Work penalties: Deliberate or reckless underpayment can attract penalties of up to $93,900 per contravention for companies. Even accidental breaches can result in enforceable undertakings.
- Reputational damage: Underpayment scandals regularly make news headlines. The damage to your employer brand can affect recruitment and customer perception.
- Employee relations: Staff who discover they've been underpaid lose trust in their employer, affecting engagement and increasing turnover. Good communication about pay practices builds trust.
Frequently asked questions
What are penalty rates in australian rostering?
Penalty rates are additional payments above the base hourly rate for work performed during unsociable hours such as evenings, weekends, and public holidays. They compensate employees for working when most people have time off and vary by industry award. Learn more about Australian award rates.
When do weekend penalty rates apply?
Weekend penalty rates typically apply from midnight Friday to midnight Sunday. Saturday rates are usually lower than Sunday rates. The exact rates and times vary by award—for example, the Hospitality Award has different rates than the Retail Award.
How do public holiday penalty rates work?
Public holiday penalty rates are the highest, typically ranging from 200% to 275% of the base rate depending on the award. Employees may also be entitled to substitute days off. Some awards distinguish between full-time, part-time, and casual employees for public holiday entitlements.
Do casual employees get penalty rates?
Yes, casual employees receive penalty rates on top of their casual loading. The casual loading (typically 25%) is added to the base rate first, then penalty rates are calculated on the loaded rate. This means casual weekend and public holiday rates can be significantly higher than permanent employee rates.
Can rostering software calculate penalty rates automatically?
Yes, modern rostering software with Australian award interpretation can calculate penalty rates automatically as you build rosters. This shows real-time labour costs, prevents surprise payroll bills, and helps ensure compliant payments.
What happens if I underpay penalty rates?
Underpaying penalty rates can result in back-pay claims covering up to six years, Fair Work penalties of tens of thousands of dollars per breach, damage to your business reputation, and potential prosecution for serious or deliberate underpayments. Use payroll integration to ensure accuracy.
