The 9-day fortnight is a compressed working pattern where you work your ordinary hours across 9 days instead of 10 — giving you every second Friday off. It is one of the most popular flexible work arrangements in Australia, particularly in professional services, government, and corporate roles.
Key Takeaways
- A 9-day fortnight means you work 9 days across a 2-week period and take every second Friday (or alternate day) off.
- Annual leave is calculated in hours or pro-rata days — taking a week off uses fewer leave days than a standard 10-day fortnight pattern.
- Public holidays on your RDO (rostered day off) may be lost or compensated — check your award or agreement.
- The arrangement must be voluntary and can usually be withdrawn by either party with reasonable notice.
- Enterprise agreements and awards often have specific rules about RDO accrual and leave interaction.
How the 9-Day Fortnight Works
Under a typical 9-day fortnight arrangement:
- Total hours per fortnight: 75 hours (for a standard 38-hour week employee, plus 1 hour of RDO accrual per week)
- Standard pattern: Work 9 days at 8.33 hours per day, with 1 RDO per fortnight
- RDO: Your rostered day off — the day you do not work each fortnight
- Longer daily hours: To compress a 76-hour fortnight (2 × 38 hours) into 9 days, each day is roughly 8.44 hours; with a 75-hour fortnight target, each day is about 8.33 hours
The RDO is typically a fixed day (e.g., every second Friday), but some employers allow flexible RDOs within the fortnight.
Annual Leave and the 9-Day Fortnight
Annual leave on a 9-day fortnight pattern works differently:
Taking a full week off: If you take a week (5 consecutive working days) of annual leave, you use 5 days of leave. But because your working pattern is 9 days per fortnight, a “week” of leave effectively covers more than half your fortnightly commitment. Your leave system should handle this by calculating leave in hours, not days.
Taking two weeks off: If you take two weeks off (10 consecutive days), you would use only 9 days of leave because one of those days is your RDO. Your annual leave balance lasts longer because your pattern has built-in days off.
RDOs during leave: If you are on annual leave and an RDO falls within that period, the RDO should not count as a leave day. The leave system must be configured to recognise your compressed pattern.
Public Holidays
Public holidays interact with the 9-day fortnight in two ways:
- Public holiday on a working day: You get the day off paid as usual. If it falls during a leave period, the holiday is not counted as leave.
- Public holiday on your RDO: You generally do not get an additional day off or pay. Some enterprise agreements provide a substitute day in lieu. Check your award.
The interaction between public holidays and RDOs is one of the most common sources of confusion. Employees often feel they lose out when a public holiday lands on their RDO, and this should be addressed clearly in the policy.
Managing Leave Liability With a 9-Day Fortnight
For employers, the 9-day fortnight can create leave accrual complexity:
- Annual leave accrues on a hours-worked basis — you accrue leave even on days you do not work (the RDO is still part of your employment period)
- Leave liability calculations must account for the compressed pattern
- An employee with a large leave balance may appear to have more “days” of leave than they actually have, because each leave day covers a longer workday
A leave management system like Leave Balance handles this automatically by tracking in hours rather than days.
FAQ
How many leave days do I get on a 9-day fortnight?
Your annual leave entitlement in Australia is 4 weeks (152 hours for a 38-hour week employee). On a 9-day fortnight, that is roughly 18 days of leave (152 ÷ 8.44 hours per day), compared to 20 days on a standard pattern. You get the same total hours off — it just takes fewer actual leave days because your working days are longer.
Can I cash out my RDO?
No — an RDO is a day off, not accrued leave. It is part of your ordinary hours arrangement. You cannot cash it out separately from your annual leave.
What if I resign mid-fortnight?
Your final pay should account for whether you have worked more RDOs than you have accrued (or vice versa). If you have taken a RDO but not worked enough hours to earn it, the employer can deduct it from your final pay.
Can my employer change my RDO day?
Yes — with reasonable notice. Your RDO day can be changed to suit operational needs, but frequent changes undermine the benefit of the arrangement. Most policies require a minimum notice period.
Does the 9-day fortnight affect long service leave?
No — your continuous service is not affected by the compressed pattern. Long service leave accrual continues as normal. When taking long service leave, you would use the same compressed pattern.
