Employment Obligations in Australia: Understanding Express and Implied Duties

When you employ staff in Australia, your obligations don’t just come from what’s written in the contract. Some duties are “express” (spelled out in writing), while others are “implied” by law and will apply even if you never put them on paper.

Understanding both is essential to building a compliant, fair and productive workplace. It also helps you avoid disputes and costly claims.

In this guide, we’ll break down the difference between express and implied duties, what each side owes the other, and practical steps to put everything on a solid footing from day one.

What Are Express And Implied Duties In Employment?

Employment obligations in Australia come from three main sources:

• Express terms (the written employment contract and any incorporated policies)
• Implied terms (duties the law reads into every employment relationship)
• Statutory obligations (requirements under laws like the Fair Work Act, WHS laws and anti-discrimination legislation)

Express duties are the obligations you and your employee agree to in writing. For example, job duties, hours, pay, confidentiality and notice of termination.

Implied duties arise from common law. They exist whether they’re written or not. For instance, employees must obey lawful and reasonable directions, and employers must provide a safe system of work.

On top of those, legislation sets minimum standards and protections that apply to most Australian workplaces. These can’t be contracted out of, even by mutual agreement.

Key Express Duties To Set Out In Your Employment Contracts

Your written terms are your first line of protection. Clear, tailored contracts reduce the risk of misunderstandings and make performance expectations crystal clear.

At a minimum, your contracts should address the following areas.

1) Job Role, Duties And Reporting Lines

Outline the position, core responsibilities, where the role sits in your structure and who the employee reports to. Add a reasonable flexibility clause so duties can evolve as the business changes.

2) Hours Of Work, Location And Flexibility

State ordinary hours, overtime arrangements (if applicable), where work is performed, and any hybrid or remote expectations. Reference roster changes and how they’ll be communicated.

3) Pay, Super And Benefits

Set out salary or hourly rate, superannuation, allowances, loadings and bonus eligibility. Clarify when pay is due and how it’s calculated (including overtime or penalty rates if they apply).

4) Leave Entitlements

Refer to minimum leave under the National Employment Standards (NES), and add any additional benefits your business offers (e.g. paid parental leave top-ups).

5) Confidentiality And IP Ownership

Protect your business by clearly stating that confidential information must not be used or disclosed, and that intellectual property created in the course of employment belongs to the business. You can also support this with a separate Non-Disclosure Agreement when appropriate.

6) Policies Incorporated By Reference

Reference the workplace policies that form part of the employment terms (for example, code of conduct, WHS, social media and IT security). This allows you to update policies without rewriting contracts. If you’re building out your policy suite, consider a foundational Workplace Policy framework so expectations are consistent and enforceable.

7) Conflict Of Interest, Outside Work And Restraints

Include clear rules about working for competitors, moonlighting and dealing with conflicts. Post-employment restraints (non-compete, non-solicit) should be carefully drafted to be reasonable in scope and length.

8) Performance Management And Termination

Explain your process for feedback, performance improvement, and what constitutes serious misconduct. Set out notice periods and any grounds for summary termination.

9) Privacy And Data Handling

Employees handle personal information daily. Reference your privacy practices and direct staff to your Privacy Policy so they know what’s expected when collecting and using customer or employee data.

10) The Right Contract For The Right Status

Use the correct agreement for the engagement type. Permanent roles should be covered by a tailored Employment Contract, while casual hires need terms that reflect the nature of casual work, such as an Employment Contract (Casual) that addresses casual loading, offers and conversion rights.

The Most Important Implied Duties Under Australian Law

Even with a comprehensive contract, the law reads in a set of “default” duties to every employment relationship. You can’t use a contract to sidestep them, and in many cases you wouldn’t want to-they support a fair and functional workplace.

Employee Implied Duties

• Obey Lawful And Reasonable Directions: Employees must follow instructions that are lawful, reasonable and within the scope of their role.
• Exercise Due Care And Skill: Workers must perform their duties with reasonable competence and care, aligned with the job’s requirements.
• Fidelity And Good Faith: Employees owe a duty of loyalty-not to damage the employer’s interests, misuse confidential information or compete while employed.
• Confidentiality (even after employment): Employees must not disclose trade secrets or truly confidential business information. This duty survives termination for genuinely secret information.

Employer Implied Duties

• Provide A Safe System Of Work: Employers must take reasonable care for employees’ health and safety, including training, supervision and safe equipment. This sits alongside statutory WHS duties; more on those below.
• Pay Wages And Provide Work (where required): Employers must pay agreed remuneration and, in some roles, provide work to maintain skills or meet contractual expectations.
• Act Reasonably In Exercising Contractual Discretions: When the contract gives the employer discretion (for example, bonus decisions), the law generally expects that discretion to be exercised honestly and reasonably.

Note: Australian courts have confirmed there’s no general implied term of “mutual trust and confidence” in every contract. However, many disputes still turn on whether parties acted reasonably, lawfully and consistently with the contract and workplace laws.

Employer Obligations You Can’t Contract Out Of

On top of express and implied terms, you must comply with statutory obligations that apply regardless of what’s in the contract.

National Employment Standards (NES)

The NES set minimum entitlements like maximum weekly hours, flexible work requests, leave, public holidays and termination notice. If a contract provides less than the NES, the NES will override it.

Modern Awards And Enterprise Agreements

Many roles are covered by a modern award that sets industry or occupation-specific minimums (like classification levels, pay rates, overtime and allowances). Make sure your contracts and payroll align with any applicable award or enterprise agreement. If you’re unsure how awards apply, get advice early-our team regularly assists with Modern Awards compliance as part of contract and policy reviews.

Work Health And Safety (WHS)

Every business has a duty to provide a safe workplace and manage risks. This captures physical safety and, increasingly, psychosocial risks like workload and workplace behaviour. A practical primer is our overview of your duty of care as an employer, which explains what “reasonably practicable” steps look like.

Anti-Discrimination, Bullying And Harassment

Federal and state laws prohibit discrimination and sexual harassment. You must take reasonable steps to prevent unlawful conduct-including clear policies, training and prompt action when issues arise. Policies and training are not optional extras; they’re evidence that you’ve taken prevention seriously.

Fair Work Protections And Termination Rules

Unfair dismissal, general protections (adverse action) and redundancy rules require you to follow fair, lawful processes. Good documentation and a consistent performance management process go a long way to reducing risk.

Privacy And Data Security

If your business handles personal information, you must manage it lawfully and securely. Staff should be trained on your Privacy Policy and understand their responsibilities when collecting, storing and accessing personal data.

Managing Breaches: Practical Steps For Employers

Even with strong documents and training, issues can arise. A calm, process-driven approach helps you resolve problems quickly and fairly.

1) Check The Contract, Policies And Applicable Law

Start by reviewing the employee’s contract, relevant policies and any applicable award. Confirm what standards apply and whether there’s a genuine breach.

2) Gather Facts And Meet With The Employee

Be fair and transparent. Outline the concerns, share any available evidence, and allow the employee to respond. Keep detailed notes.

3) Consider Proportionate Responses

Outcomes should match the severity: from coaching and training, through to warnings and, for serious misconduct, termination. If termination is on the table, double-check notice, procedural fairness and any award/EA requirements.

4) Protect Confidential Information And IP

If the issue involves misuse of confidential information, act swiftly-revoke access, recover devices where appropriate, and remind the employee of continuing obligations. A well-drafted confidentiality clause and supporting NDA make enforcement more straightforward.

5) Look After Health And Safety

If there’s a safety or conduct issue, your WHS duties require you to control risks. Separate parties if needed, adjust duties temporarily, and escalate to a formal investigation where serious allegations arise.

6) Document Everything

Accurate records of conversations, warnings, performance plans and outcomes will be critical if the matter escalates to a claim. Consistency and clarity are your friends.

Getting Your Documents Right From Day One

Most employment disputes trace back to unclear expectations or gaps in documentation. A few targeted documents make a big difference.

• Employment Contract: Tailored terms for each role help you set hours, pay, duties, confidentiality, IP assignment, notice and more. Use the right form of Employment Contract for permanent roles, and a specific casual contract when hiring casuals.
• Workplace Policies: A clear policy suite (code of conduct, WHS, bullying/harassment, leave, IT/social media, privacy and grievance handling) sets standards and supports enforcement. Start with a core Workplace Policy framework and build from there.
• Privacy Policy: If your team handles personal information, your Privacy Policy should be accessible and staff should be trained on it.
• Confidentiality And IP: Strong confidentiality clauses and, where needed, a supporting Non-Disclosure Agreement protect trade secrets and client data.
• Performance And Conduct Processes: Having a documented process for feedback, warnings, investigations and termination aligns with Fair Work expectations and reduces claims. If you’d like structure, we can assist with a practical performance management process suited to your business.

It’s also worth training managers on your documents. Policies are only effective if your leaders know how to apply them consistently and fairly.

How Express And Implied Duties Work Together Day-To-Day

In practice, your express terms and implied duties complement each other. Here’s how that plays out in common scenarios.

Directions And Flexibility

Your contract might include a flexibility clause so duties can shift as the business grows. The implied duty to obey lawful and reasonable directions then supports day-to-day instructions within that reasonable scope.

Confidentiality And Post-Employment Risks

Confidentiality is covered by express terms and also protected by implied duties. If an employee downloads client lists before leaving, your confidentiality clause plus the implied duty not to misuse confidential information will both assist in enforcement.

WHS And Performance Load

Employers must take reasonable steps to manage workload and psychosocial risks as part of WHS obligations. Align your WHS policies with the implied duty to provide a safe system of work-and don’t forget the leadership piece: managers need to be trained to spot issues early and respond appropriately.

Performance Problems

When performance drops, rely on express performance obligations in the contract, but also manage the process fairly and consistently with workplace laws and awards. Good documentation, clear expectations and a structured improvement plan usually lead to better outcomes for both sides.

Frequently Asked Questions

Can I Override Implied Duties With Contract Wording?

Generally, no for core obligations like obeying lawful and reasonable directions or providing a safe system of work. While you can clarify and supplement duties in the contract, courts are reluctant to recognise wording that tries to sidestep fundamental protections.

Do Implied Duties Apply To Casuals?

Yes, implied duties apply to the employment relationship regardless of status. The practical application may differ due to the nature of casual work, which is why it’s important to use a proper casual contract and manage offers of work, rostering and communication carefully.

What If My Policies Aren’t Incorporated Into The Contract?

Policies can still guide behaviour and support a fair process, but incorporating them by reference strengthens your position. Just make sure policies are accessible, up to date and applied consistently.

How Do WHS Duties Interact With Implied Duties?

They reinforce each other. The implied duty to provide a safe system of work sits alongside your statutory WHS obligations. Both expect you to identify risks, implement controls, train staff and review controls regularly. A useful starting point is our guide to an employer’s duty of care.

Key Takeaways

• Express duties live in your contracts and policies; implied duties are read into every employment relationship by law and apply even if not written down.
• Strong employment contracts, the right policies and targeted training align day-to-day expectations with your legal obligations.
• Core implied duties include employees obeying lawful and reasonable directions and acting with loyalty, and employers providing a safe system of work and paying agreed remuneration.
