Real Cost of Leaving an Allied Health Role Vacant for 30 Days.
A clinic director in Melbourne once told us that keeping a role open for an extra two weeks saved her service the cost of using an agency. Twelve weeks later, two experienced practitioners had resigned, caseloads were capped at 60% of capacity, and the service had spent three times the original agency fee on temporary staffing. She filled the role eventually. The cost of waiting had not been avoided. It had been deferred.
This is the most common miscalculation in allied health workforce management. The vacancy itself feels like a waiting cost. What it actually is, is an accumulating one.
Lost billable hours are the figure most practice managers reach for first, and they are not wrong to. An occupational therapist generating 30 billable hours per week at an average rate of $190 per session represents close to $5,700 in weekly revenue. Thirty days of that role sitting empty is approximately $22,800 in unrealised billing. For a physiotherapy or speech pathology role in a busy metropolitan service, the numbers are comparable.
But the billing loss is only the visible layer. The harder cost sits underneath it, and most services only encounter it after the fact.
When a role sits unfilled, the remaining team absorbs the caseload. This is rarely announced formally. It happens gradually, through intake coordination quietly routing new referrals to whoever has capacity, through existing practitioners agreeing to a slightly longer list for a few weeks that becomes a few months. The overload builds incrementally until someone raises it, or until someone leaves because they never got around to raising it.
How a single vacancy become multiple ones?
Australia’s allied health turnover rate has been climbing consistently since 2022. NDIS growth expanded the market faster than the training pipeline could fill it, and practitioners who feel the strain of stretched caseloads now have more options than ever before. The departure of a single team member, if it creates sustained pressure on the remaining staff, materially increases the probability of further departures within the following two quarters.
This is the compound effect that does not appear in the vacancy cost calculation. A single unfilled speech pathology role becomes a retention problem for the two practitioners absorbing the overflow. The service is now managing the cost of one vacancy while inadvertently creating the conditions for two more.
There is also the recruitment cost to factor in. A reactive hire made under pressure, whether through a job board, a generalist agency, or a compromised brief, costs more and takes longer than a proactive one made while the team is stable. The urgency narrows the candidate pool. The speed compresses the screening. The compliance checks that feel optional when there is pressure to fill a seat are the ones that create liability down the line.
What 30 days actually mean in 2026?
The Australian allied health market in 2026 is not a buyer’s market. The 2025 Occupation Shortage Driver Report confirmed that fill rates for health professionals remain significantly below demand, with an average of 1.3 suitable applicants per vacancy in some allied health categories. In speech pathology and occupational therapy, that number is lower.
What this means practically is that a vacancy that opens today competes with every other service that opened a similar vacancy this month. The candidate who would be the right fit for your role is not waiting. They are employed, and they are being approached by other services who started their recruitment process before the vacancy officially existed.
The services filling roles quickly in this market are the ones with a recruiter relationship already in place when the vacancy opens. Not the ones who begin the search after the resignation letter lands.
What to do instead?
The practical answer to the 30-day vacancy cost is not to eliminate recruitment timelines. It is to start them earlier. A proactive workforce conversation with a specialist recruiter, before a vacancy exists, means that when a role does open, there is already a shortlist, a compliant screening process, and a network being worked on your behalf.
It also means that when urgency does arrive, it does not override the process. Compliance gaps, credential oversights, and cultural mismatches are almost always the product of a hire made in a hurry. Building the relationship before the pressure exists is the most cost-effective risk mitigation available to any allied health service.
If your service has a role that has been open for more than 30 days, or if you are managing a workforce that is one resignation away from a capacity problem, it is worth a conversation. Radical Recruitment works exclusively in allied health and education recruitment across Australia.
