Quick answer: Neither option wins every time. A healthcare staffing agency is usually the better fit for short-notice cover, leave, surge demand and roles you are still testing. In-house hiring usually wins for stable, ongoing rosters where continuity and culture matter most. Most WA providers end up using both. The useful question is not “which is cheaper?” but “what does an unfilled shift cost us, and how long can we carry it?”

If you run an aged care home, a disability service, a GP clinic or a private health facility in Western Australia, you have probably faced this decision on a Monday morning with a roster gap and no obvious fix. This guide sets out how to think it through.

1. What a vacant shift actually costs

A vacant shift rarely shows up as a single line in the budget. The cost is spread across the rest of the operation:

• Overtime and extra shifts. Existing staff cover the gap. That is paid time, and it is also fatigue.
• Burnout and turnover risk. Teams that cover gaps for long stretches are more likely to start looking elsewhere, which creates the next vacancy.
• Lost capacity. Fewer staff can mean fewer appointments, closed beds or delayed admissions.
• Manager time. Rostering around a gap, chasing cover and interviewing all pull your clinical and operations leads away from their actual work.
• Compliance exposure. Residential aged care providers must have a registered nurse onsite and on duty 24 hours a day unless an exemption applies. Each home also has its own care minutes target, based on a sector-wide average of 215 minutes of direct care per resident per day, including 44 minutes from a registered nurse (Department of Health, Disability and Ageing; Aged Care Quality and Safety Commission). For those providers, a gap that runs on is a compliance problem as well as a rostering one.

Add these up for your own service before you compare options. A simple way to do it: for one typical vacant shift, write down what you pay in overtime, what you lose in capacity, and how many hours of manager time it consumes. Then compare that to the cost of covering the shift another way. The cost of carrying a gap is almost always higher than it feels week to week.

2. Where agency cover makes sense

Agency cover is built for situations where speed and flexibility matter more than long-term continuity:

• Short-notice absences such as sick leave, carer’s leave or an unexpected resignation.
• Planned leave and surge periods, including school holidays, winter illness peaks and accreditation preparation.
• Regional and remote roles where the local candidate pool is thin and you need access to a wider network.
• Bridging a permanent hire. Cover the roster while your own recruitment runs, so the team is not stretched in the meantime.
• Testing a new service line or shift pattern before you commit to permanent headcount.

A good agency also takes on the sourcing and checking work, so your managers are not running that process on top of everything else. For GP clinics specifically, see how this plays out in our guide to GP clinic staffing across Perth and regional WA.

The honest trade-off is that agency cover costs more per shift than a permanent employee and brings less continuity. Staff who rotate through have less time to learn your residents, patients, systems and routines. That is a real cost, and the answer is to use agency cover where it fits rather than as a default.

3. Where in-house hiring is the right call

In-house recruitment is usually the stronger choice when:

• The role is stable and ongoing. If you need the same shift filled every week for the foreseeable future, a permanent or part-time employee is the natural fit.
• Continuity of care matters most. Aged care, disability support and community health depend on staff who know the people they care for.
• You are hiring clinical leadership. Roles that shape culture and standards, such as clinical leads and senior nurses, are better built from within.
• You have a strong employer brand and a manageable local pool. If candidates already want to work for you, direct hiring plays to that strength.
• You have the internal capacity to recruit properly. Advertising, screening, interviewing, reference checks and onboarding take real time. If your team has it, in-house works well.

It is not the right call when the recruitment effort itself keeps the gap open longer than the service can sustain.

4. Compliance and credentialing: your risk either way

This is where providers sometimes underestimate the difference between options. Whoever supplies the nurse, the standard your service is held to does not change.

• Registration. Ahpra says the public online register is the only reliable source of information on a practitioner’s registration status (Ahpra: using the register). Check it before you offer work, and keep track of renewals (nurses and midwives renew by 31 May each year) and any conditions on registration. Employers may also have a legal duty to make a mandatory notification if the threshold is met (Ahpra: mandatory reporting).
• Disability work. Workers in risk-assessed roles for registered NDIS providers need a valid NDIS Check clearance (in some cases a valid pending application may allow work to start, subject to conditions). In WA, screening is run by the Worker Screening Unit at the Department of Communities (WA Government: NDIS Check application guide).
• Your own policies. Your organisation’s policies may call for further checks. Confirm what applies to your service and roles.

If you use an agency, ask what it checks, how it keeps those checks current, and what evidence you receive. A reputable agency will answer plainly. Questions worth asking:

1. Which checks are completed before a worker is put forward, and how often are they refreshed?
2. Can you see the evidence, or only a statement that checks are done?
3. How does the agency handle a registration condition or lapse that appears mid-engagement?
4. What does the agreement say about who is responsible if a check turns out to be wrong? (Your own legal or compliance adviser should review this.)

NHR says it will verify qualifications, AHPRA registration and compliance before you meet anyone. If you are comparing healthcare employment agencies, ask every one of them for the same detail.

5. Ramp times: set realistic expectations

Neither route is instant, and anyone who promises a fixed timeline for a clinical hire is guessing.

In-house hiring has several stages, and each takes time: writing and advertising the role, screening and interviewing, reference and registration checks, an offer, notice periods for candidates who are already employed, then orientation. The total can run longer than expected, particularly for regional roles or specialised skills.

Agency cover removes some of those stages, because sourcing and checking run alongside your own planning. It still depends on the role, the location, the shift pattern and who is available. Metropolitan casual and short-term cover can move faster than permanent regional placements, and a good agency will give you an honest read on the likely timeframe up front, rather than a guarantee.

Orientation applies to both. Even a fully qualified nurse needs time to learn your systems, protocols and people. Build that into your plan whichever route you choose.

6. A simple way to decide

7. The hybrid approach most providers end up with

In practice, the strongest staffing plans use both. A permanent core team provides continuity and culture. A relationship with a healthcare staffing agency provides a flexible layer for leave, peaks and the gaps between resignations and replacements.

Some providers also use agency placements as a trial period for roles they intend to make permanent. That can work well, but check the agreement terms before you plan on it.

Frequently asked questions

Is healthcare agency staffing always more expensive than hiring in-house?

Per shift, agency cover usually costs more than a permanent employee. But a fair comparison includes the cost of the vacancy, overtime, lost capacity, manager time and recruitment effort. The right answer depends on how long the gap lasts and what it costs your service.

Can I use an agency and still hire permanently?

Yes. Many providers cover the roster with agency staff while they recruit. Check the agreement for any terms that apply if you later hire an agency worker directly.

Who is responsible for checking a nurse’s registration?

Ahpra points to its online register as the only reliable source for registration status, so check it before you offer work and keep track of renewals and conditions. If you use an agency, ask what it checks and what evidence it provides, and have your own compliance adviser review how responsibility is shared in your agreement.

Does agency staffing work for regional WA?

It can help where the local pool is thin, but timelines and availability vary by location and role. Ask for an honest assessment early.
