What Is a Secondment Role and When Should Businesses Use It?

If you’re growing a team, “secondment” might already be on your radar. Maybe you’re launching a new project, covering a parental leave period, or developing future leaders. A secondment can be a smart, low-risk way to flex your workforce while giving employees valuable experience.

But to get the benefits without the headaches, you’ll want to understand how secondments work in Australia, what to include in your paperwork, and the key legal points to get right. This guide breaks it all down in plain English so you can decide if a secondment role is the right tool for your business-and implement it smoothly.

Below, we explain what a secondment is, the different ways you can set one up, common advantages and risks, and the essential legal steps to stay compliant and protect your organisation.

What Is a Secondment Role?

A secondment is a temporary arrangement where an employee steps out of their usual role (their “home” role) to work in a different role for a defined period. This could be within the same team, in another department, or with a different organisation entirely.

In a secondment, the employee usually remains employed by their original or “home” employer. They perform duties for a “host” team or organisation and are expected to return to their home role (or another agreed role) at the end of the secondment. Typical duration ranges from a few weeks to 12–24 months, depending on the purpose.

Common Secondment Scenarios

• Internal secondment: A marketing specialist moves into a product role for six months to help launch a new line.
• Group secondment: An employee in a parent company works in a subsidiary’s project team for a year.
• External secondment: A private sector analyst is seconded to a government agency to support a reform project (or vice versa).

Secondments are different from transfers or promotions because they are temporary and designed to bring skills back to the home employer (unless everyone later agrees to a permanent move).

How Do Secondments Work in Australia?

Secondments can be structured in a few different ways. The right option depends on whether the host is inside your business or a separate organisation, and who handles day-to-day direction and payroll.

Internal Secondment (Same Employer)

The employee stays employed by you and simply moves to another role or team for a defined period. This is the simplest option from a legal and payroll perspective. You’ll typically issue a short variation letter confirming duties, reporting lines, duration, and what happens at the end.

External Secondment (Separate Organisation)

Here, the home employer remains the employer of record, but the employee performs work for the host organisation. Key points to consider:

• Management and direction: The host usually directs day-to-day work, while the home employer remains responsible for core employment obligations unless agreed otherwise.
• Payroll: Either the home employer continues to pay the employee (and invoices the host), or the host pays under a recharge arrangement set out between the organisations.
• Policies: The agreement should make clear which policies apply (e.g. code of conduct, safety, IT, conflicts of interest) and how issues are escalated.

When external secondments resemble labour hire (supplying workers to another business for a fee), be aware that licensing laws may apply in some states. In Victoria, for example, you may need to consider labour hire licensing requirements if your arrangement meets the definition.

Typical Steps to Set Up a Secondment

1. Define the need: Project support, capability building, coverage for leave, or partnership objectives.
2. Confirm role details: Duties, reporting lines, location/remote work, duration, and any higher duties or allowances.
3. Agree commercial terms (if external): Who pays, recharge method, confidentiality and IP ownership, and indemnities between the businesses.
4. Document the arrangement: A written secondment agreement between organisations (if external) and a variation or side letter with the employee.
5. Onboard and monitor: Host induction, safety training, access permissions, and regular check-ins with all parties.
6. Close-out and return: Handover, performance review, and re-entry to the home role (or other agreed outcome).

Pros and Cons of Using a Secondment Role

Why Businesses Choose Secondments

• Targeted capability: Quickly plug a skills gap for a project or peak period without a permanent hire.
• Development and retention: Stretch assignments grow your people and often improve engagement and loyalty.
• Partnership value: Secondments deepen relationships with client and partner organisations and build shared expertise.
• Low-risk trial: Test a potential leader or specialist in role-specific tasks before committing to a permanent move.

Risks and Pitfalls to Watch

• Backfill pressure: Moving a strong performer can leave a short-term gap-plan coverage in advance.
• Legal complexity (external): Payroll, WHS, confidentiality, and IP can get tricky without clear documents.
• Misaligned expectations: Without clarity on duties, performance management, and return-to-role, disputes can arise.
• Licensing and compliance: Supplying staff externally may trigger labour hire rules in some states.

A clear written framework, regular communication, and a thoughtful return plan usually reduce these risks significantly.

Legal Issues to Get Right in a Secondment

Secondments sit at the intersection of employment, safety, and commercial law. Getting the basics right upfront protects everyone involved.

1) Contracts, Awards and Policy Alignment

Review the employee’s existing employment contract and any applicable modern award or enterprise agreement. If duties, location or hours change, document the variation and ensure the arrangement still meets minimum conditions. Where relevant, align which policies apply in the host environment (for example, harassment, IT use, conflicts, and safety). If you need guidance on award coverage and minimum standards, consider the framework set by modern awards and keep your documentation consistent with those requirements.

Where disputes or complex variations are expected, it can be worth getting tailored advice from an employment lawyer before the secondment starts.

2) Pay, Allowances and Entitlements

Secondments don’t automatically lock in the exact same pay and benefits an employee had before. What matters is that the arrangement complies with the National Employment Standards and any applicable award or enterprise agreement, and that any changes are made lawfully with the employee’s informed agreement.

• Higher duties: If the seconded role has higher classifications or allowances, those obligations generally apply during the secondment.
• Changes to remuneration: You can adjust remuneration by agreement, provided minimum entitlements are maintained or exceeded.
• Leave and service: If employment remains with the home employer, service typically continues and leave entitlements accrue as normal. If employment transfers to the host (i.e. it becomes a new employment relationship), continuity depends on whether transfer-of-business rules apply and what is agreed.

If you need to formalise adjustments, use a concise variation letter or an appropriate deed for more complex terms. Keeping arrangements consistent with the relevant modern awards framework will reduce risk.

3) Work Health and Safety (WHS)

Both the home employer and host typically owe WHS duties and must consult, cooperate and coordinate to ensure the seconded employee’s health and safety. That includes site inductions, training, risk management, and incident reporting lines.

Make it explicit which policies and procedures apply day-to-day. A clear allocation of responsibilities supports your broader duty of care and helps prevent gaps.

4) Confidentiality and Intellectual Property

Secondments often involve access to new systems, data and know-how. Put strong confidentiality provisions in place and be clear about who owns any intellectual property created during the secondment. In external secondments, it’s common for the host to own project-specific IP while the home employer retains ownership of background IP-spelling this out avoids disputes later.

Practical tools include an organisation-to-organisation agreement and individual NDAs. Where the work product has material value, consider support from an intellectual property lawyer.

5) Labour Hire and Licensing

When you second employees to another business for a fee, the arrangement may meet the definition of labour hire in some states. If so, licensing obligations can apply. For example, Victorian businesses may need to consider the labour hire licence in Victoria. Check whether your arrangement requires a licence (or exemption) where your employee will work.

6) Ending the Secondment and Returning

At the end of the secondment, the parties should follow the written terms. There is no universal legal right to return to the exact same role unless you’ve agreed to it. Many employers promise a return to the home role (or a comparable role), but you should document this upfront to avoid confusion.

• Return to role: Confirm the return date, location, any refresher training and any changes to duties.
• If the home role has changed: Consult with the employee and consider alternatives; if there’s no suitable role, standard restructuring or redundancy processes may apply.
• If everyone wants a permanent move: End the secondment and issue a new employment contract with the host, ensuring final pay and entitlements with the home employer are settled.

The clearer your exit plan at the start, the smoother this stage will be for the team and the employee.

What Documents Should You Put in Place?

Your documents should match the structure you choose (internal versus external) and the complexity of the role.

• Organisation-to-Organisation Agreement (External Secondment): A commercial agreement between the home and host setting out duties, supervision, payment/recharge, indemnities, WHS responsibilities, confidentiality, IP and insurance. In many cases, this can be framed as a tailored Service Agreement between the businesses.
• Employee Variation or Side Letter: A short letter confirming the secondment role, duration, reporting lines, work location, pay/allowances (including higher duties if relevant), policies, and end-of-secondment outcomes. If you need a more formal change, consider a Deed of Variation.
• Confidentiality Protections: Use targeted confidentiality terms and, if needed, a Non-Disclosure Agreement for the employee and/or between the organisations.
• Policy Alignment: Confirm which workplace policies apply at the host location (safety, IT, code of conduct, grievance, bullying/harassment) and ensure the employee receives and acknowledges them. If you need to refresh your policy framework, a practical starting point is a clear, consolidated workplace policy set.
• Employment Contract (Permanent Move): If the secondment becomes permanent with the host, close out the secondment and issue a new contract with the host. Where issues arise, getting input from an employment lawyer can help avoid pitfalls.

Where IP or data access is significant to the role, don’t rely on standard templates-ensure your confidentiality and ownership clauses are tailored to the actual project and systems involved.

When Does a Secondment Make Sense?

Secondments are most effective when there is a specific, time-bound need and the employee will gain capabilities that benefit your business in the long run. Consider using secondments to:

• Accelerate a critical project, product launch or transformation.
• Backfill a role for parental leave, long service leave or sabbaticals.
• Develop emerging leaders through complex, cross-functional work.
• Strengthen a strategic partnership or client relationship.
• Support group entities where knowledge transfer is a priority.

If the role is ongoing, headcount is stable and the work will continue beyond 12–24 months, a permanent transfer or hire may be more appropriate than a secondment.

Key Takeaways

• A secondment is a temporary move to a different role or organisation, usually with the employee staying employed by their home employer and returning at the end.
• There’s no universal right to return to the exact same role-set expectations in writing about the end of the secondment, return arrangements or permanent moves.
• Make sure pay and conditions during the secondment meet minimum standards under the National Employment Standards and any relevant award or agreement, and record any changes with the employee’s consent.
• Clarify WHS responsibilities, policies, confidentiality and IP ownership in your documents; external arrangements may also raise labour hire licensing issues in some states.
• Use the right paperwork: a business-to-business agreement (for external secondments), an employee variation letter, targeted confidentiality terms, and updated policies where needed.
• Secondments work best for defined, time-bound needs and capability building; for ongoing needs, consider a permanent transfer or hire instead.
