The term "locum" comes from the Latin locum tenens, meaning "to hold the place of". In Australian hospitals, locum doctors do exactly that. They step into rostered positions when permanent staff are unavailable due to leave, illness, recruitment gaps, or unexpected demand surges. The model has shifted considerably over the past decade. Where locum work was once viewed as a stopgap for early-career physicians or semi-retired consultants, it now represents a deliberate staffing strategy for hospitals and a viable long-term career path for clinicians across all stages of practice.
Why Hospitals Use Locum Doctors
Hospitals engage locum doctors to maintain service continuity without the administrative burden of permanent recruitment. A specialist taking parental leave, a department head on extended sick leave, or a sudden resignation in Emergency Medicine all create immediate gaps that cannot wait three months for a formal appointment process to conclude. Locum placements allow medical directors to keep wards staffed, theatres running, and rosters covered while permanent solutions are developed.
The demand for locums peaks around certain predictable periods: summer leave rosters in December and January, conference season in the first and third quarters, and whenever new training rotations begin. But unpredictable surges matter just as much. A flu season that hits harder than forecast, a cluster of staff illness, or an unexpected retirement can force departments to scramble. Locum doctors absorb that variability without requiring the hospital to overstaff permanently employed positions during quieter months.
Preferred supplier arrangements have streamlined the procurement side of locum engagement for many public hospitals. Best Practice Medical holds preferred supplier status with NSW, QLD, VIC, ACT, WA, Tasmanian and NT Health, as well as Ramsay Health Care and Healthscope, meaning hospital clients can begin accessing a credentialed doctor network without lengthy onboarding or tender processes. This removes a significant administrative barrier for facilities working under tight timelines.
What Locum Doctors Actually Do
Locum doctors perform the same clinical work as their permanently employed peers. They assess patients, write notes, prescribe, order investigations, perform procedures, attend ward rounds, and participate in handovers. The only operational difference is the duration of their engagement and the contractual relationship with the facility.
Some locums take single shifts to cover a sick colleague. Others accept multi-week blocks to cover parental leave or a recruitment gap. A smaller subset work continuously as locums across multiple facilities, moving between contracts rather than holding a single permanent role. The clinical expectations remain the same regardless of contract length. A locum anaesthetist in a private day surgery is expected to manage the same case mix and documentation standards as the staff specialists. A locum registrar in a metropolitan Emergency Department works the same triage, resus, and discharge workflows as the permanent registrars on the roster.
The NHS England guidance for supporting locum doctors emphasises that short-term placements do not reduce the need for proper induction, access to clinical supervision, or participation in governance activities such as morbidity and mortality reviews. Australian hospitals follow a similar principle. A locum is not a visitor; they are a rostered member of the clinical team for the duration of their engagement.
Specialties that rely heavily on locum doctors include Anaesthetics, Emergency Medicine, Psychiatry, ICU, Obstetrics and Gynaecology, and Surgery. These disciplines experience higher staff turnover, more unpredictable leave patterns, and greater difficulty recruiting into regional or less desirable rosters. Across all major hospital disciplines, locums provide the flexibility that keeps departments operational when permanent headcount falls short.
Credentialling and Compliance for Locum Doctors
Before any locum doctor steps into a clinical role, their credentials must be verified. This is not a formality. Hospitals carry legal and clinical liability for the practitioners they credential, and locum placements require the same rigour as permanent appointments. The verification process includes AHPRA registration, medical indemnity insurance, relevant college memberships, immunisation records, and facility-specific requirements such as orientation to the hospital's electronic medical record system.
Best Practice Medical verifies AHPRA registration, medical indemnity insurance, relevant college memberships, and facility-specific requirements before any doctor is placed. The process is managed in-house, with Brad Nelmes-a practising clinician-overseeing credentialling standards. ISO 9001:2015 certification means the process is independently audited annually, providing hospital clients with documented assurance that the locum arriving on shift meets the same standards as a permanent employee.
| Credential Type | Verification Required | Frequency |
|---|---|---|
| AHPRA Registration | Current and unrestricted | Every placement |
| Medical Indemnity | Adequate cover for role and specialty | Every placement |
| College Membership | RANZCP, ANZCA, ACEM, RANZCOG as relevant | Every placement |
| Facility Orientation | EMR access, clinical governance, site induction | First shift at facility |
| Immunisation Records | Hepatitis B, MMR, varicella, influenza | Annual or as per policy |
The credentialling process is more complex for specialists than for junior medical officers. A Visiting Medical Officer or consultant-level locum requires verification of fellowship status, scope of practice, and procedural privileges. A hospital engaging a locum anaesthetist for obstetric lists needs confirmation that the doctor holds current ANZCA fellowship and has recent experience in obstetric anaesthesia. A locum psychiatrist working in an inpatient unit must demonstrate registration with RANZCP and familiarity with Mental Health Act procedures in the relevant state. These details matter clinically and medico-legally, and they cannot be assumed or self-reported.
The WHO's guidance on health workforce migration raises ethical considerations for international recruitment of temporary staff, particularly when doctors are drawn from countries with existing workforce shortages. In Australia, most locum doctors are already practising domestically, either as permanent employees taking additional shifts or as full-time locums moving between facilities. International medical graduates working as locums typically hold standard AHPRA registration and have completed the same assessment pathways as their locally trained peers.
How Locum Doctors Are Paid
Payment structures for locum doctors vary depending on the engagement model. Some locums are employed directly by the hospital on a short-term contract and paid through the facility's payroll. Others work as independent contractors, invoicing the hospital or the recruitment agency for shifts completed. The distinction matters for tax, superannuation, and indemnity insurance purposes.
Contractors typically invoice at an hourly or daily rate negotiated in advance. The rate reflects specialty, seniority, location, and notice period. A locum anaesthetist covering a last-minute theatre list at a private hospital commands a higher rate than a planned, multi-week registrar placement in a metropolitan public hospital. Regional placements often attract higher rates again, particularly when the facility is difficult to staff and travel is required.
In the United States, the CMS guidance on reciprocal billing and fee-for-time arrangements outlines strict rules about how locum tenens physicians can bill Medicare, including the 60-day limit for using the locum modifier. Australian hospitals do not operate under Medicare billing restrictions in the same way, but the principle of clear contractual terms and transparent payment structures applies equally. A locum doctor needs to know, before accepting a shift, whether they are invoicing as a contractor or being paid as an employee, what the rate is, and how expenses such as travel and accommodation are handled.
For doctors working as contractors, invoice management can become a friction point. Chasing outstanding payments, clarifying invoicing procedures with finance departments, and managing ABN and GST requirements add administrative overhead to clinical work. Some agencies handle this on behalf of the doctor, arranging and submitting invoices to the healthcare facility and following up on any outstanding amounts. This removes the burden of billing from the clinician and ensures payment terms are clear from the outset.
What Early-Career Doctors Should Know About Locum Work
Junior doctors considering locum work often weigh the financial upside against concerns about career progression, training accreditation, and job security. The AMA's advice for early-career physicians considering locum tenens work highlights the importance of understanding how locum work fits into longer-term career goals, particularly when training requirements or college supervision hours are at stake.
In Australia, locum shifts can count toward training time if they meet the relevant college's criteria for supervision, case mix, and educational oversight. A registrar in an accredited Emergency Medicine training program can usually count locum shifts at another accredited site, provided the shift is logged correctly and the supervisor holds appropriate qualifications. But not all locum work qualifies. A term spent working exclusively in a non-accredited private hospital or a rural facility without the required supervision structure may not count toward fellowship, regardless of the clinical experience gained.
The decision to work locum shifts as a junior doctor is often driven by immediate financial need or a desire to gain exposure to different clinical environments. A registrar rotating through a metropolitan teaching hospital may take weekend locum shifts at a regional base hospital to see a different patient demographic and work with less immediate senior support. The clinical learning is real, but the administrative consequences need to be understood before the shift is booked. Does the shift count toward training? Is the supervising consultant recognised by the college? Will the hospital provide a logbook entry or case documentation that can be submitted for assessment?
For doctors further along in their careers, locum work can serve different purposes. Some specialists use locum contracts to trial a new city or hospital before committing to a permanent move. Others prefer the flexibility of choosing their own roster rather than being locked into a fixed on-call schedule. A small subset work exclusively as locums, moving between facilities and maintaining a portfolio career rather than a single institutional affiliation. This model works best for specialists in high-demand disciplines where work is plentiful and credentialling is straightforward.
Differences Between Short-Term and Long-Term Locum Placements
Short-term locum placements are reactive. A doctor calls in sick, a shift is unfilled, and a locum is booked to cover. The timeline from request to placement can be as short as a few hours, particularly for Emergency Medicine or Anaesthetics where rosters are published weeks in advance and gaps become visible early. These placements require a doctor who is already credentialed at the facility or who holds portable credentials that can be verified quickly.
Long-term placements are planned. A specialist takes six months of parental leave, and the department needs coverage from a defined start date to a defined end date. A resignation creates a permanent vacancy, but recruitment will take twelve weeks, so a locum is engaged to bridge the gap. These placements allow time for thorough credentialling, site orientation, and handover from the outgoing clinician. The locum has time to learn the department's workflows, build rapport with nursing staff, and participate in governance meetings rather than simply showing up for clinical shifts.
The billing and contractual arrangements differ as well. A single-shift locum is almost always paid as a contractor, invoicing for the hours worked. A six-month locum may be employed directly by the facility on a fixed-term contract, with superannuation, leave entitlements, and payroll tax handled in the same way as a permanent employee. The choice depends on the facility's preference and the tax treatment of the engagement.
From a clinical perspective, the difference is continuity. A locum working the same department for three months learns the patient cohort, becomes familiar with local protocols, and can take on more complex or longitudinal cases. A locum covering a single night shift in Emergency Medicine works from the triage list and hands over at the end of the shift without follow-up. Both roles are necessary, but they serve different operational needs.
How Hospitals Should Onboard Locum Doctors
A locum doctor arriving for their first shift at a new facility faces the same learning curve as any new starter, but with less time to adjust. Permanent employees typically receive multi-day orientation programs, buddy shifts, and staged increases in clinical responsibility. A locum may receive a 30-minute site tour and immediate allocation to the roster. This creates risk.
Effective onboarding for locum doctors includes access to the electronic medical record, familiarity with the hospital's clinical pathways and escalation protocols, and clear identification of who to contact for support. A locum anaesthetist needs to know where the difficult airway trolley is kept, how to contact the on-call intensivist, and what the local protocol is for managing malignant hyperthermia. A locum psychiatrist needs to know how to access the Mental Health Act paperwork, who holds the on-call psychiatry registrar pager, and what the escalation pathway is for an acutely disturbed patient.
Hospitals that treat locums as temporary visitors rather than rostered team members experience higher adverse event rates, poorer communication during handover, and more frequent near-misses in clinical care. The NHS England guidance on safe induction for locum doctors recommends that every locum receive a documented induction tailored to their role, even for single-shift placements. The same principle applies in Australian hospitals. A locum should not be left to figure out the resuscitation trolley location or the blood bank phone number mid-emergency.
What Questions Locum doctors Should Ask Before Accepting a Placement
Before accepting a locum placement, a doctor should clarify the scope of the role, the level of supervision available, and the logistical details of the engagement. The following questions are worth asking upfront rather than discovering the answers mid-shift:
What is the case mix I will be expected to manage? A locum Emergency Medicine registrar needs to know whether the department sees trauma, paediatrics, and mental health presentations, or whether certain patient groups are diverted to other facilities. A locum anaesthetist needs to know whether the lists include paediatric cases, obstetrics, or regional blocks, and whether senior support is available on-site or on-call.
What level of supervision and backup is available? A junior locum working without adequate senior support is a clinical and professional risk. A clear answer about who supervises the role, how to contact them, and what the escalation pathway looks like should be provided before the contract is signed.
What are the payment terms and invoicing procedures? Is the doctor employed or contracting? What is the hourly or daily rate? When is payment due? Are travel and accommodation covered, and if so, by whom? These details should be confirmed in writing before the first shift.
Does the placement count toward training or college requirements? For registrars and fellows in training, this question can determine whether a locum shift advances their career or simply provides income. The hospital should be able to confirm accreditation status, supervision arrangements, and whether logbook documentation will be provided.
What is the accommodation and travel arrangement for regional placements? A locum travelling interstate or to a regional facility needs to know whether accommodation is provided, whether flights are booked in advance, and what happens if travel is delayed or disrupted. Ambiguity here creates unnecessary stress and can lead to last-minute cancellations if a doctor realises they are expected to self-fund a $600 flight and find their own accommodation in an unfamiliar town.
How Recruitment Agencies Support Locum Placements
Recruitment agencies sit between hospitals and doctors, managing credentialling, rostering, invoicing, and communication. A hospital engaging a locum through an agency delegates much of the administrative burden to that agency, but retains clinical and governance oversight of the doctor once they are on-site.
Good agencies verify credentials before presenting a candidate, brief the doctor on the facility's expectations, and provide 24/7 support if issues arise during the placement. Poor agencies treat locum placement as a transactional exercise, matching names to shifts without considering clinical fit, credentialling specifics, or the doctor's actual scope of practice. The difference becomes apparent when a doctor arrives for a shift and discovers that the role, the case mix, or the level of supervision is not what they were told.
For hospital clients managing complex or ongoing locum requirements, some agencies offer partial or full roster management services. Rather than filling individual shifts reactively, the agency works with the facility to plan ahead, identify gaps, and maintain continuity of cover across departments. This is particularly useful for departments with high locum dependency, such as Psychiatry or regional Emergency Medicine, where permanent recruitment is difficult and turnover is frequent.
Doctors considering working with a recruitment agency should assess the agency's credentialling standards, responsiveness, and whether they have direct relationships with the facilities they service. Agencies with preferred supplier status across state health departments can place doctors more quickly because the procurement friction is already resolved. Agencies without those relationships may struggle to get a doctor credentialed and rostered in the necessary timeframe, particularly in public hospitals where procurement processes are rigid.
Risks and Complaints in Locum Work
Locum work carries reputational and professional risk if not managed correctly. A locum doctor is often less familiar with a facility's culture, its clinical pathways, and the unwritten rules that govern how work gets done. This increases the likelihood of miscommunication, procedural errors, or conflict with permanent staff who resent the higher pay rates or perceive locums as less committed to the department.
Complaints about locum doctors typically fall into a few categories: inadequate handover, poor documentation, clinical errors due to unfamiliarity with local protocols, or interpersonal conflict with nursing or medical staff. Some of these complaints reflect genuine clinical deficiencies. Others reflect the structural challenge of integrating a temporary team member into a high-pressure environment without adequate onboarding.
For doctors, a complaint lodged during a locum placement can follow them to future roles if it results in a notification to AHPRA or a formal disciplinary process. The absence of an ongoing relationship with the facility means there is less institutional loyalty and more willingness to escalate issues formally rather than resolving them informally. A locum should take documentation, handover, and communication just as seriously as they would in a permanent role, if not more so.
Hospitals mitigate these risks by ensuring locums receive proper induction, have access to senior support, and are not placed in roles beyond their scope. A facility that engages a locum ICU registrar without confirming their procedural competence in central line insertion or intubation is creating a foreseeable risk. A facility that rosters a locum psychiatrist to manage acute inpatient admissions without confirming their familiarity with the Mental Health Act is doing the same.
Locum doctors are a necessary and growing part of Australia's hospital workforce. They provide flexibility for facilities managing unpredictable demand and leave patterns, and they offer clinicians a viable alternative to traditional permanent employment. The model works best when credentialling is rigorous, onboarding is thorough, and communication between hospitals, doctors, and agencies is clear. Best Practice Medical connects exceptional doctors with extraordinary locum opportunities across Australia, offering tailored services for medical staffing with thorough candidate screening and placement systems designed for time-poor professionals who need the match to be right the first time.
