The cost of an unfilled shift: NSW warehouse, 2026.
A no-show does not just cost you the shift. Computed from current award rates in MyGig’s engine and sourced assumptions, putting one unfilled 8-hour warehouse shift right costs $485 to $572, up to 78% more than the $322 shift you planned. Here is every number.
The scenario
A Sydney distribution centre rosters a casual storeworker for a standard 8-hour weekday shift under the Storage Services and Wholesale Award (MA000084), Storeworker Grade 2. At the rates effective 1 July 2026, that shift costs $321.63 all-in: wages, 12% superannuation, and workers compensation. The worker does not show, and the work still has to happen. There are two common ways to put it right, and neither is cheap.
Why the overtime path costs 78% more
When a shift goes unfilled on the day, most operations cover it by extending the people already on site. Under the award’s Monday-to-Saturday overtime rules, MyGig’s engine prices those hours for this classification at 1.4 times the casual hourly rate for the first two hours and 1.8 times after that. Eight hours of cover that would have cost $279.68 in planned wages costs $475.46 in overtime wages, a 70% premium before anyone in the office lifts a finger. Add the workers comp on those wages and roughly 90 minutes of supervisor time spent ringing around, re-rostering, and re-briefing, and the total lands at $572.22.
The agency route looks cheaper on paper, at roughly $485, but it depends on an emergency candidate actually being available at short notice, and the ~25% margin is typically buried in the hourly rate rather than itemised.
The annual drag
One shift is an annoyance. The pattern is a budget line. Australian absence-management research (Direct Health Solutions’ national absence survey) puts unplanned absence at 7 to 8% of payroll. For a mid-size NSW operation running 30 casuals at 24 hours a week across 48 weeks, that is a casual payroll of roughly $1.17 million, and an absence bill of about $88,000 a year at the midpoint, before the overtime premiums above are counted.
“Every warehouse no-show in NSW now costs up to $572 to put right, 78% more than the shift that was planned.”

Methodology
Storage Services and Wholesale Award (MA000084), Storeworker Grade 2, adult casual: $34.96/hr including the 25% casual loading, effective from the first full pay period on or after 1 July 2026. Source: MyGig award engine (the same data that prices every MyGig shift), built from Fair Work Commission pay guides.
Wages 8 x $34.96 = $279.68; superannuation guarantee 12% on ordinary time earnings = $33.56 (ATO rate from 1 July 2025); workers compensation at 3% of wages = $8.39 (NSW icare warehousing classifications typically run ~2-4.5%; we use 3%).
Monday-Saturday overtime for this classification priced by MyGig's engine at 1.4x the casual hourly rate for the first 2 hours and 1.8x thereafter: 2 x $48.94 + 6 x $62.93 = $475.46. Superannuation is generally not payable on overtime (it falls outside ordinary time earnings), so none is added. Workers comp 3% = $14.26. Supervisor scramble time: 1.5 hours at $55/hr = $82.50 (the same admin-cost assumption our savings calculator publishes).
The planned loaded cost ($321.63) plus a 25% agency margin ($80.41): compliant warehouse and logistics agencies typically run 15-30% on loaded cost, and short-notice fills sit at the upper end; we use 25%. Plus the same $82.50 of scramble time.
Direct Health Solutions' national absence-management research puts unplanned absence at 7-8% of payroll. Example payroll: 30 casuals x 24 hrs/wk x 48 weeks at entry Grade 1 ($33.85/hr) = $1,169,856; 7.5% midpoint = ~$87,700.
Lost throughput and missed SLAs (real, but they vary too much by site to average honestly), penalty-hour scenarios (weekend and night shifts make every number above larger), payroll tax (below the $1.2M NSW threshold in the example), and hiring costs when a no-show becomes a resignation. The figures here are the conservative floor.
