12:9 Roster Salary Calculator – Twelve On, Nine Off Pay Breakdown
The 12:9 roster — twelve days on, nine days off — is a less common but well-balanced FIFO pattern found in mining and oil & gas operations. With a generous nine days off between swings, this roster offers more recovery time than a standard 14:7 while maintaining strong annual earnings. It's an excellent option for workers who find two weeks on site too demanding.
What Is a 12:9 Roster?
A 12:9 roster means you work twelve consecutive days on site followed by nine days off. The 21-day cycle repeats approximately 17.4 times per year, giving you around 209 working days with 12-hour shifts. The longer rest period compared to a 14:7 makes it more sustainable, while still delivering competitive income. This roster is occasionally found in specialised mining and oil & gas operations across WA and QLD.
