Swing patterns explained: 2/1 vs 4/1, and the best pattern for the lifestyle

Ask three superintendents which swing pattern is right and you will get four answers. The numbers are less emotional, and one pattern keeps winning the popularity contest.

How to read a swing pattern

FIFO rosters are written as weeks on slash weeks off. A 2/1 means two weeks of work followed by one week at home. The on swing generally means 12 hour shifts every single day; the off weeks are your guaranteed time back in Perth or Brisbane.

The patterns you will actually meet

• 2/1 (two weeks on, one off): the WA default and the most common standard roster in the state. Steady income and two thirds of the year on site, which also means long stretches away from home.
• 2/2 (two on, two off): the even-time roster, half the year at home. Workers and recruitment specialists consistently agree even-time patterns give the best work-life balance and the best mental health recovery. It is the recruiting ad that writes itself.
• 4/1 (four on, one off): the endurance option. Maximum earnings and heavy coverage for construction phases and shutdowns, but 28 consecutive days on site is a genuine test, and crew know it.
• 8/6 (eight days on, six off): short cycles for sites within cheap flying distance of a capital.

Whichever pattern is on the table, weigh the physical toll, and if crew are flying across states, the time zone difference stacks on top of the shift fatigue.

What 4/1 buys you

Coverage. A 4/1 worker is on site 80 percent of the time against 67 percent for 2/1, so fewer people cover the same seats. On a spreadsheet, 4/1 wins every time.

What 4/1 costs you

Fatigue: week four on site is where the incident stats start climbing, and regulators know it. Longer swings need real fatigue controls, on paper, that you can show someone.

Turnover: time at home is the currency of FIFO. Sites running 4/1 pay the coverage saving straight back out in recruitment and training. Ask whoever writes your job ads which pattern gets applicants.

Changeover crunch: longer swings concentrate changeover days. Flights, rooms, and the wet mess all spike at once.

The real world runs mixed

Most sites end up with operators on 2/1, staff on 8/6, and a shutdown crew on 4/1 for one quarter only. That is fine. The trap is keeping every combination straight on one page so changeover days do not collide. That is the point where the whiteboard and the spreadsheet both give up.

The short version

Steady state? 2/1 remains the cost default. Competing for experienced crew? Even-time 2/2 is the pattern workers themselves rate best, and it shows in application numbers. Defined project window with an end date? 4/1, with fatigue controls in writing. Whatever you pick, put it in writing before the quarter starts, not during.

Pattern definitions per Australian FIFO recruiters; the even-time preference is echoed consistently by workers, including FIFO threads on Reddit.

What we see across mixed pattern rosters

The debate is usually framed as coverage against cost, but watching mixed pattern rosters run, the deciding factor is nearly always lifestyle. The patterns crews stay on are the ones their lives can absorb year after year, and the even time rosters keep winning that contest quietly. The sites that accept it early spend less on recruitment and carry steadier crews. The ones that fight it keep learning the same lesson through their turnover bill.
