The Reasonableness Test in Australian Business Law

“Reasonableness” pops up everywhere in Australian business law. You’ll see it in contracts, employment decisions, privacy compliance, leases and how you deal with customers.

But what is the reasonableness test, how do courts apply it, and what does that mean for the way you draft terms or make decisions in your business?

In this guide, we break down the reasonableness test in plain English and explain how to apply it day-to-day so you can reduce legal risk and build fair, enforceable practices from the start.

What Is The Reasonableness Test?

The reasonableness test asks a simple question: would a fair, sensible person, in the same situation and with the same information, think the term or decision is reasonable?

In practice, “reasonable” depends on context. Courts don’t use a one-size-fits-all rule. They look at the specific facts: the purpose of the clause or decision, the risks you’re managing, industry norms, the bargaining power of each party and whether a less restrictive option could have achieved the same result.

This flexible approach is why reasonableness appears across many areas of law. It helps judges balance business interests with fairness.

Where Does Reasonableness Show Up In Small Business Contracts?

Most small businesses rely on standard terms and regular contracts. Here are common places a reasonableness test will be applied.

1) Restraint Of Trade (Non-Compete, Non-Solicit)

Restraints must go no further than reasonably necessary to protect legitimate interests (for example, your confidential information or client connections).

• Scope: Restrict the specific services/products that compete with yours, not a broad industry.
• Time: Choose a duration that fits your sales cycle or onboarding period (e.g. 6-12 months).
• Geography: Tie the area to where you actually operate or have clients.

Overly broad restraints are likely to be unenforceable because they’re not “reasonable” in protecting your business without unnecessarily limiting the other party’s right to work.

2) Limitation Of Liability

Limiting liability is standard, but the limitation must be reasonably tailored to the risks of the deal. A court may scrutinise a limitation of liability clause that tries to exclude responsibility for anything and everything, especially where one party had much stronger bargaining power.

Think about:

• Carve-outs for serious issues (e.g. fraud, wilful misconduct, IP infringement, personal injury).
• Cap size based on fees paid or an agreed multiple, aligned to the risk profile.
• Proportionate responsibility where multiple causes contribute to loss.

3) Indemnities And Set-Off

Indemnities should target clearly identified risks and be proportionate to what each party controls. A sweeping indemnity that makes the other party pay for losses entirely outside their control may not be reasonable.

Similarly, a broad set-off clause that lets you withhold payment for unrelated disputes can be risky. Narrow the clause to genuine, closely connected claims and follow a fair dispute process.

4) Liquidated Damages And Late Fees

Pre-agreed fees for delay or breach should reflect a reasonable estimate of likely loss at the time of contracting, not a penalty. If a charge is aimed at punishing the customer, it may be unenforceable. Benchmarks, industry practices and your operating costs can help support reasonableness.

5) Waivers And Risk Acknowledgments

Waivers are more likely to be upheld if they are clear, brought to the customer’s attention and proportionate to the activity’s risks. Overreaching waivers can be challenged. If you use waivers, check they align with the Australian Consumer Law and are not unfair. This is one reason many businesses review whether waivers are legally binding in their circumstances.

How Do Courts Decide What’s Reasonable?

When a court applies the reasonableness test, it usually considers factors like:

• Legitimate interest: What are you trying to protect (confidential information, IP, operational continuity, safety)?
• Proportionality: Does the term or decision go only as far as needed to protect that interest?
• Context and industry standards: Is this common and accepted in your sector?
• Bargaining power and transparency: Did both parties understand and accept the term? Was it hidden in fine print?
• Alternatives: Could a less restrictive option have achieved the same protection?
• Practical impact: What does this mean in real life for the other party and for you?

Example: A 24‑month Australia‑wide restraint against a junior salesperson in a local service business is unlikely to be reasonable. But a 6‑month restraint limited to your client list and local area might be.

Practical Steps To Draft Reasonable Terms

If you want your contracts to protect your business and stand up to scrutiny, build reasonableness in from the start.

1) Tie Every Clause To A Legitimate Purpose

Ask “what risk does this clause manage?” Then limit the clause to that risk. For example, limit non-solicit restraints to customers the person actually worked with in the last 6-12 months, rather than all customers ever.

2) Use Layered Restraints

Consider cascading durations or areas (e.g. 12 months / 6 months / 3 months) so a court can enforce the longest reasonable option. This structure often improves enforceability.

3) Right-Size Your Liability Structure

Pick a liability cap aligned to the contract value and your insurance. Keep carve-outs for high‑risk scenarios. A balanced limitation of liability clause is more likely to be upheld.

4) Keep Payment Protections Proportionate

Make indemnities, set-off rights and security interests proportionate to what the other party can control. Overbroad protections are more likely to be challenged.

5) Be Clear And Upfront

Reasonableness is easier to defend when important terms are highlighted before signing. Use plain English, avoid surprises and provide an opportunity to ask questions.

6) Document Your Rationale

Keep internal notes on why a clause is drafted the way it is (e.g. claims history, regulatory obligations, safety concerns). If your terms are later challenged, contemporaneous notes can support reasonableness.

7) Review Standard Terms Regularly

If your business model or risk profile changes, update your standard form contract. A periodic contract review helps maintain reasonable, enforceable terms as you grow.

Reasonableness In Employment And Workplace Policies

Employment decisions are routinely assessed for reasonableness under workplace laws and policies.

Employment Contracts

Courts look closely at restraints, confidentiality obligations, IP ownership, deductions and set-off provisions in employment agreements. Terms should be targeted, transparent and fair in the circumstances of the role.

Using a clear, tailored Employment Contract is a practical way to set expectations and embed reasonable processes (for example, performance management and notice).

Work Directions And Policies

Employers can issue lawful and reasonable directions. “Reasonable” considers the nature of the role, safety, operational needs, and whether the direction is proportionate. Similarly, policies (like mobile phone use, leave approvals or WFH expectations) should be balanced and consistently applied.

Restraints, Garden Leave And Confidential Information

If you include non-compete or non-solicit provisions, keep them no broader than needed to protect customers and confidential information. If you plan to use garden leave, align the period with your notice terms and operational risk. If you ask departing staff to return property or certify deletion of files, make the steps clear and practical to comply with.

Reasonableness In Privacy, Consumer Law And Leases

The reasonableness test isn’t limited to contracts. Here’s how it appears across other key compliance areas for small businesses.

Privacy: “Reasonable Steps”

Under the Privacy Act, businesses must take reasonable steps to protect personal information. What’s “reasonable” depends on your size, the sensitivity of data, the harm if breached and available security measures. Start with access controls, encryption where appropriate, staff training and a clear Privacy Policy that reflects how you actually handle data.

If you share confidential information with partners, a targeted Non-Disclosure Agreement helps demonstrate reasonable protections beyond internal policies.

Australian Consumer Law (ACL): Reasonable Expectations And Timeframes

The ACL looks at what a reasonable consumer would expect, and whether your terms or conduct are fair and not misleading. It also assesses whether goods are provided within a reasonable time and whether remedies are provided without undue delay. Keep your advertising accurate, your refunds process clear and your remedial timeframes practical for the product or service involved.

Commercial Leases: Consent Not To Be Unreasonably Withheld

Commercial and retail leases often require a landlord’s consent (for example, to assign or sublease) “not to be unreasonably withheld.” Landlords should assess the tenant’s financials, business use and fitout impacts, then decide promptly and on objective grounds. Tenants should supply full information early and follow the process set out in the lease. If you’re negotiating or disputing these terms, a focused commercial lease review can identify what “reasonable” looks like under your specific lease and state laws.

A Simple Framework To Apply The Reasonableness Test

When you’re unsure whether a term or decision is reasonable, run through this quick framework.

1. Identify the legitimate business interest you’re protecting (safety, confidentiality, service quality, compliance, financial risk).
2. Map the practical impact on the other party (staff, customer, supplier, tenant).
3. Check proportionality (scope, time, geography, money) against that interest.
4. Consider industry norms and any regulatory requirements.
5. Ask whether a less restrictive option would still protect you.
6. Be transparent and consistent in how you apply the term or decision.
7. Record your rationale (this helps if the decision is challenged later).

If your draft term or decision survives this test, you’re far more likely to meet a legal reasonableness standard if it’s ever scrutinised.

Common Pitfalls That Fail The Reasonableness Test

• One-sided “just in case” drafting: Overbroad clauses that try to cover every possible risk, regardless of context.
• Silence and surprise: Hiding material terms in fine print without drawing attention to them.
• No link to purpose: Restraints, fees or indemnities that don’t connect to a clear business interest.
• Copy-paste policies: Borrowed policies that don’t reflect how your business actually works in practice.
• Inconsistent application: Enforcing rules against some customers or staff but not others.

Avoid these traps by aligning your contracts and decisions with your genuine risk profile and documenting why.

Key Documents That Help Show Reasonableness

Clear, tailored legal documents won’t just manage your risks - they also demonstrate that you’re acting reasonably and transparently.

• Contract Review: Refresh your standard terms so liability limits, indemnities, fees, restraints and dispute processes are proportionate and clear.
• Privacy Policy: Explains what personal data you collect, why, and the reasonable steps you take to protect it.
• Non-Disclosure Agreement: Reasonable confidentiality protections when sharing information with partners, suppliers or contractors.
• Employment Contract: Sets fair terms on duties, confidentiality, notice and any tailored restraint of trade.
• Limitation Of Liability Clause: Balanced caps and carve-outs aligned to the contract value and risk.
• Set-Off Clause: Narrow and connected to genuine, related claims, not a catch-all withholding right.

Key Takeaways

• The reasonableness test asks whether a fair, sensible person would see your term or decision as proportionate in context.
• Courts consider purpose, proportionality, transparency, bargaining power, industry norms and practical impact.
• Draft contracts with clear links to legitimate interests (e.g. confidentiality, safety, service quality) and right-size restraints, indemnities and liability caps.
• In employment, ensure contracts, directions and policies are balanced, transparent and consistently applied.
• Outside contracts, “reasonable steps” also apply - for example, in data protection, ACL remedies and lease consents.
• Regular reviews of your standard terms and policies help keep protections enforceable and reasonable as your business evolves.
