What Agency Theatre Nurses Actually Cost Australian Private Hospitals

Most cost comparisons between agency and permanent theatre nurses are rubbish, and hospital executives know it.
They compare the agency's hourly charge against a permanent nurse's base salary. That is not a comparison. The permanent nurse also costs superannuation, leave, payroll tax and workers compensation. Ignore those and you inflate the case for permanent recruitment to the point where nobody believes it.
So let us do it properly. Every figure below is either published, or clearly labelled as an estimate. If a number is a guess, we say so.
What a permanent theatre nurse actually costs
Take a Level 2 registered nurse in a private hospital theatre, full time, 38 hours a week.
Component | Amount | Source |
Base salary | $90,000 | SEEK, scrub and scout average |
Superannuation at 12% | $10,800 | ATO, rate from 1 July 2025 |
Annual leave loading (17.5% on four weeks) | $1,212 | Standard entitlement |
Payroll tax (approx. 5%, varies by state) | $5,100 | State revenue offices |
Workers compensation (approx. 1.7%) | $1,530 | Industry rate estimate |
Total annual employment cost | $108,600 |
That is roughly $2,090 a week to employ that nurse. Not $1,730. The on-costs add about 21% on top of base.
What an agency theatre nurse costs
Agency perioperative nurses in Australia are commonly advertised at $50 to $65 an hour, rising higher for specialist or short-notice cover. On top of the nurse's pay, the agency carries the same statutory on-costs the hospital would otherwise carry (super, payroll tax, workers compensation), plus its own margin. All of that is rolled into a single hourly charge to the hospital.
Australian labour hire margins are generally quoted at 15% to 40% on top of the loaded worker cost.
Applying that to the advertised pay rates gives a working range of roughly $100 to $130 an hour for a theatre RN on a standard weekday shift. Penalty rates on afternoons, weekends and public holidays push it higher again.
This is an estimate, not a published figure. Agencies do not disclose their bill rates. We have built the range from advertised pay rates plus documented labour hire margins, and we would rather tell you that than dress it up as a fact. If you know your own bill rate, use it. The conclusion below does not change.
The comparison, done honestly
Here is where most agency versus permanent comparisons cheat. They forget that a permanent nurse takes leave, and that the line still needs covering while she is away.
So we have added it. Five weeks of leave cover at agency rates, on the permanent side of the ledger. This makes the permanent case worse, and it is still not close.
Covering one full-time theatre RN line for 12 months, agency charged at $110 an hour:
Permanent | Agency | |
Employment cost | $108,600 | Nil |
Agency charge (38 hrs x 52 weeks) | Nil | $217,400 |
Cover for five weeks annual leave | $20,900 | Included above |
One-off permanent placement fee | $7,500 | Nil |
Year one total | $137,000 | $217,400 |
Year two onwards | $129,500 | $217,400 |
Year one difference: about $80,000. Every year after that: about $88,000.
And the agency figure repeats. There is no year two saving. You pay it again, and again, for as long as the line stays unfilled.
The break-even is measured in weeks
The number that matters is not the total. It is the premium: the gap between what agency costs and what permanent costs for the same cover.
At $110 an hour, agency costs about $4,180 a week. The permanent equivalent, including leave cover, is about $2,490 a week. The premium is roughly $1,690 a week.
A $7,500 permanent placement fee is recovered once that premium has accumulated to $7,500. Here is how that plays out across the whole range, including the cheapest agency rate we could find.
Agency charge | Weekly premium | Weeks to recover a $7,500 fee | Annual cost gap |
$90/hr | $930 | 8.1 weeks | $48,400 |
$100/hr | $1,310 | 5.7 weeks | $68,000 |
$110/hr | $1,690 | 4.4 weeks | $88,000 |
$130/hr | $2,450 | 3.1 weeks | $127,000 |
Even at the lowest agency rate we could find, a permanent placement fee pays for itself inside two months. At a typical rate, inside five weeks. Everything after that is money the hospital keeps.
Note what that table does not contain: a rate at which agency is cheaper. There isn't one. Agency would need to charge under about $65 an hour to beat permanent, and nobody does.
The costs that never make it onto the invoice
The hourly rate is the part you can see. It is not the expensive part.
Orientation drag. Perioperative orientation takes months, not days. Every rotating agency nurse consumes clinical educator and NUM time without ever reaching the productivity of a settled permanent nurse. That time is not billed to anyone, but it is not free.
Theatre productivity. The Victorian Auditor-General put the direct cost of a productive theatre hour at $2,004 in 2017. A team that does not know each other's rhythm turns over more slowly. A single cancelled case costs more than a week of the agency premium.
Count reliability. We want to be careful here, because the evidence does not support a claim that agency nurses are unsafe, and we are not going to make one. What the research does support is narrower and still important: count discrepancies rise with team unfamiliarity and with staff changes during a case. A stable scrub and scout pairing who have worked a hundred lists together is not the same clinical instrument as two people who met at handover.
The core team. Heavy agency use loads overtime onto your permanent staff, who are frequently training people earning more than they do. That is how you lose the nurses you already have. Turnover then drives more agency use, which drives more turnover.
When agency is genuinely the right call
Agency staffing earns its premium in specific situations, and pretending otherwise would be dishonest.
Short-notice sick leave. Parental leave cover. An unexpected resignation while a permanent search runs. A sudden list expansion before you can recruit. In all of these, agency turns a fixed cost into a variable one, and the alternative is a cancelled list. That is a good trade.
The problem is not agency staffing. The problem is agency staffing a stable, funded, ongoing role. That is where the premium stops buying flexibility and simply becomes a leak.
One number to put in your board pack
Set an internal trigger. If a permanent line has been agency-covered for more than six weeks, it has passed break-even against the cost of recruiting for it properly.
Six weeks is the rule of thumb at typical rates. If you have negotiated hard and you are paying near the bottom of the market, give yourself eight. Either way it is weeks, not quarters, and it is almost certainly already behind you.
Make it a standing report item. Six weeks, and the search should already be running.
