WHS in labour hire works best when responsibilities are explicit, practical and reinforced in everyday site operations. Problems usually start when host employers and labour providers assume the other party is handling something important.
This guide outlines a practical way to think about accountability between host employers and labour hire providers. The starting point under work health and safety law is that the host and the provider can both hold a duty to the same worker at the same time. Engaging labour hire does not hand your obligations to someone else—it simply means two parties now have to coordinate, each managing the risks they are best placed to control.

Key takeaways
- Shared duty does not mean vague duty. Both parties need defined controls and evidence.
- The host controls the site and day-to-day environment, so site-specific risks and supervision matter heavily.
- The provider still has obligations around worker suitability, onboarding support and communication of known risks.
- The most reliable safeguard is writing down who is responsible for each control before a worker mobilises, rather than sorting it out after an incident.
Where accountability usually sits in practice
Host employer responsibilities typically include:
- Safe plant, systems and site conditions. The host controls the physical workplace, so the equipment, layout and systems of work that a contingent worker steps into are the host’s responsibility, the same as for any direct employee.
- Site induction and local procedures. Only the host can explain the specific hazards, access rules and emergency procedures for that site, and this needs to happen before work starts.
- Day-to-day supervision and task allocation. Because the host directs the work hour to hour, it is best placed to monitor how tasks are actually being done and to step in when something is unsafe.
- Hazard reporting and incident response. Contingent workers need to know how to raise a hazard and what happens in an incident, using the same reporting channels as everyone else on site.
Labour provider responsibilities typically include:
- Screening workers for suitability, licences and competencies. The provider should confirm a worker has the tickets, experience and physical capability for the role before they are put forward, not leave it to be discovered on site.
- Communicating relevant role requirements and known risks. Workers should arrive understanding the nature of the role and any hazards the provider already knows about, so the host’s induction builds on a reasonable base.
- Maintaining contact and escalation pathways. The provider stays the worker’s employer, so it needs an open line to check in, take concerns and act when something is wrong.
- Supporting incident follow-up and worker welfare. If a worker is hurt or raises a problem, the provider has a role in follow-up, support and any return-to-work arrangements alongside the host.
Controls that reduce ambiguity
- Documented site assessment: role demands, environment, risks and supervision model. Capturing this in writing gives the provider what it needs to screen properly and makes the host’s expectations explicit rather than assumed.
- Clear induction evidence: not just attendance, but what was actually covered. A signed attendance sheet proves someone was in the room; recording the content proves the right hazards and procedures were explained.
- Role-fit checks: tickets, competencies, physical requirements and any mandatory pre-start steps. Confirm these against the role definition before mobilisation so gaps surface early, not on the first shift.
- Escalation paths: who gets called when a concern is raised on shift. Both the host supervisor and the provider contact should be named so a worker is never left unsure who to tell.
Common breakdowns
- The role brief is too vague, so unsuitable workers are sent. When the provider only has a job title to work from, it cannot match a worker to the real demands of the site.
- The host assumes the provider explained the site risks in detail. Providers can only brief on what they know; site-specific hazards still need the host’s induction.
- The provider assumes the host will identify every capability gap on day one. Day-one supervision is not a substitute for proper screening before a worker arrives.
- No one owns worker check-ins once mobilisation is complete. Without an agreed owner, early problems with fit, fatigue or understanding go unnoticed until they escalate.
A practical employer checklist
- Define role requirements before requisitions go out. Clear tasks, tickets and conditions let the provider screen accurately and reduce mismatches on site.
- Confirm pre-start evidence before workers arrive on site. Check licences, competencies and any mandatory steps are in place rather than assuming they are.
- Use a consistent site induction and record completion. A standard induction applied to every contingent worker keeps coverage even and gives you a record if it is ever questioned.
- Make supervisor responsibilities explicit for contingent workers. Name who oversees each labour hire worker so safety oversight does not fall between the host and provider.
- Review incidents and near misses with the provider, not in isolation. Joint review surfaces whether the cause sat with screening, briefing or site conditions, and prevents repeat issues.

FAQ
Does using labour hire transfer WHS responsibility away from the host?
No. Hosts still control the work environment and must manage site risks, supervision and safe systems of work. Work health and safety duties cannot be contracted away, so the host’s responsibility for the workplace continues alongside the provider’s.
What is the biggest practical risk?
Gaps between what was assumed and what was actually checked before work starts. Good onboarding and role clarity prevent many problems.
How should the host and provider divide responsibilities?
As a general rule, the provider takes the lead on worker suitability, screening and communication, while the host takes the lead on site conditions, induction and day-to-day supervision. The most important step is to agree and document that division before work starts, so neither party assumes the other has a control covered.
