Restraint Of Trade Clauses: Essential Australian Employment Insights

Restraint of trade clauses are one of the most common - and most misunderstood - parts of Australian employment contracts. They can protect your business when key people move on, but they can also be difficult to enforce if they’re drafted too broadly or implemented the wrong way.

Whether you’re hiring senior talent or you’re an employee being asked to sign a new contract, it pays to understand what these clauses do, when they hold up in court, and how to make them reasonable from the start.

Below, we break it down in plain English so you can confidently manage restraints of trade in Australia and avoid costly disputes later.

What Is A Restraint Of Trade Clause?

A restraint of trade clause is a promise in a contract that limits a worker’s activities during or after employment. The aim isn’t to stop someone from earning a living. It’s to protect legitimate business interests - like confidential information, customer relationships and the stability of your team.

You’ll usually see restraints inside an Employment Contract or executive agreement. They may also appear in contractor agreements and business sale contracts.

Common Types Of Restraints

• Non-compete: Restricts working for, or starting, a competing business within a defined time and area.
• Non-solicit: Prevents approaching or soliciting your clients, suppliers or prospects for a period after leaving.
• Non-poach: Prevents enticing your employees or contractors to leave and join the former employee’s new venture.
• Confidentiality: Protects trade secrets and commercially sensitive information (often supported by a standalone Non-Disclosure Agreement).
• Intellectual property: Confirms that work created in the course of employment belongs to the employer and can’t be used elsewhere without consent.
• Garden leave: Requires an employee to stay away from the workplace while still being paid during their notice period - a useful way to protect relationships and information before they exit. More on garden leave.

These clauses should be tailored to the role and the real risks in your business. A blanket “industry-wide” ban rarely works.

Are Restraints Enforceable In Australia?

Yes - but only if they go no further than reasonably necessary to protect a legitimate business interest. Australian courts are cautious about restraints because they limit a person’s right to work and compete. As a result, broad, catch-all clauses often fail.

What Interests Can You Legitimately Protect?

• Confidential information and trade secrets (pricing, algorithms, product roadmaps, marketing plans).
• Goodwill and customer connections, especially where the employee was the “face” of your brand or service.
• Stability of your workforce, where poaching would cause real disruption.

Preventing ordinary, fair competition on its own is not a legitimate interest. A restraint that exists “just to stop competition” is unlikely to stick.

How Do Courts Assess Reasonableness?

• Scope of activities: Does the clause target specific risky activities, or does it ban all work in the industry?
• Duration: Is the period sensible in your sector? Depending on the role, 3–12 months is common. Longer restraints require stronger justification.
• Geography: Is the area limited to where the employee actually worked, had influence or where your customers are? National or global restraints need clear reasons.
• Role and seniority: Seniority, access to information, and influence all matter.
• Consideration: If you add or strengthen a restraint after employment starts, fresh consideration (e.g. a pay rise, bonus, promotion or other tangible benefit) is typically legally required for the new promise to be binding - not just “best practice”.

NSW vs Other States: Reading Down And Cascading Clauses

In New South Wales, the Restraints of Trade Act 1976 gives courts a specific power to “read down” an overbroad restraint to a reasonable scope, rather than strike it out entirely. This is why many NSW contracts use “cascading” or step clauses with multiple time periods and geographic options - a court can enforce the narrowest reasonable option.

Outside NSW, courts generally won’t rewrite a clause to make it reasonable. They may sever clearly separable parts (the “blue pencil” approach), but they won’t choose a narrower alternative that isn’t already properly drafted into the contract. If a restraint goes beyond what’s reasonable, it risks being unenforceable in those jurisdictions. Careful drafting is essential.

Drafting Restraints That Hold Up

A well-drafted restraint is clear, proportionate and tailored to the genuine risks in your business. Use the following principles to improve enforceability from day one.

1) Link The Clause To Legitimate Interests

Explain in the contract what you’re protecting (client connections, confidential information, workforce stability). This shows a court the clause was designed to safeguard real business value, not to unreasonably limit someone’s career.

2) Choose Proportionate Time, Area And Activities

Set the narrowest restraint that still protects you. For example, a six‑month non-solicit that covers customers the employee dealt with in the 12 months before exit may be reasonable in many service-based roles. Broader non‑competes usually require stronger justification linked to seniority, strategy access or unique IP.

3) Use Cascading Options (But Draft Them Properly)

Cascading restraints list decreasing options (e.g. 12/9/6/3 months and Australia/state/city). In NSW, a court can select a narrower option that is reasonable, thanks to the Restraints of Trade Act. In other states, cascading clauses can still help if each option stands on its own and can be severed cleanly, but you can’t rely on a court to “fix” an overreach that isn’t clearly drafted.

4) Define Clients, Prospects And Confidential Information

Be specific: define “client” as, for example, anyone the employee had material dealings with in the 12 months prior to exit. Define “confidential information” so there’s no confusion about what must not be used or disclosed. Specific definitions reduce disputes.

5) Align With Role, Remuneration And Promotion

Restraints that match the seniority and pay level are easier to justify. If you strengthen restraints on promotion, document the changes and the benefit provided at that time. For stand‑alone restraints (for senior hires, founders or equity participants), a tailored Non‑Compete Agreement may be appropriate alongside your main contract.

6) Layer Protection - Don’t Rely On Non‑Compete Alone

Confidentiality, IP assignment, non‑solicit and non‑poach clauses often provide more targeted and enforceable protection than a broad non‑compete. Use layered safeguards so you’re not depending on a single, sweeping restriction.

7) Keep Contracts Current

Update restraints when roles change, your service lines evolve or you expand to new markets. Regular contract maintenance reduces the risk that a clause feels outdated or disconnected from the employee’s actual risk profile. If you’re unsure what to update, an employment lawyer can tailor the wording to your business.

Implementing Restraints (Hiring To Exit) Without Burning Bridges

Good drafting is only half the story. How you implement and manage restraints can make or break enforceability - and employee relationships.

Use Clear Contracts From The Start

Issue the contract before the person starts, give time to consider it, and encourage independent advice. If you add or strengthen restraints mid‑employment, ensure you provide fresh consideration (for example, a pay rise or promotion) and record it clearly in writing.

Safeguard Information While They’re Employed

Access controls, confidentiality training and “need-to-know” practices reduce the risk that sensitive information is taken in the first place. If a resignation is tendered, consider measures like limiting system access, reassigning accounts and, where appropriate, placing them on garden leave during the notice period.

Run A Professional Exit

Do a proper handover, remind the person of post‑employment obligations, and confirm the key points by email. Return‑of‑property checklists and access audits are simple steps that prevent later disputes. Consistent messaging at offboarding can be supported by your Employee Termination Documents Suite.

Coordinate With Related Policies

Restraints work best alongside strong confidentiality, conflicts and social media policies. In some cases, a limited non‑disparagement provision (used thoughtfully) can help protect your brand during departures.

Tailor By Role: A Few Common Scenarios

• Senior executives and founders: Courts are more likely to uphold reasonable restraints for leaders with strategic oversight and deep client access. Contracts may include bespoke non‑competes and longer notice or garden leave to allow orderly transitions.
• Sales, account management and professional services: Customer connection is often the main risk. Tight non‑solicit and non‑poach restraints that map to the actual portfolio the person managed tend to be the focus.
• Contractors and consultants: Similar principles apply, but the clause must reflect a genuine contractor relationship. For independent contractors who run their own business, heavy‑handed non‑competes can be hard to justify - scope restraints appropriately in a clear Contractors Agreement.

Disputes And Enforcement: A Practical Roadmap

Most restraint issues resolve commercially without court action. The goal is to protect relationships and information - not to litigate if you can avoid it. Here’s a sensible pathway.

1) Gather Facts Quickly

Identify what’s at risk: Which clients? What information? Which employees? Preserve evidence (emails, CRM logs, download records) and keep internal notes neutral and factual.

2) Send A Firm, Fair Letter

A carefully worded letter can set out obligations and request undertakings not to breach them. Keep the tone professional and focused on concrete risks, not threats.

3) Negotiate Practical Undertakings

Many matters settle via undertakings such as not contacting a defined list of clients for a set period, deleting confidential information and not poaching named employees. Where appropriate, confirm the agreement in a Deed of Release and Settlement so everyone is clear on the rules.

4) Apply For Urgent Relief If Needed

If there’s imminent risk of irreparable harm, you may seek an injunction (a court order) to pause the conduct while the dispute is resolved. Success often turns on how precisely the restraint is drafted and the evidence of real risk to your business.

5) Damages And Costs

In some cases, you can seek compensation for losses caused by a breach. However, litigation is expensive and time‑consuming, so a commercial resolution is often the most cost‑effective path (especially where a quick undertaking protects the core relationships you care about).

For Employees: What If You’re Asked To Sign Or You’re Moving On?

Don’t panic - and don’t ignore it. Read the clause carefully and ask practical questions: How long? Which clients? Which competitors? Which geography? If it feels too broad, propose narrowing it to the accounts you actually manage, the region you actually cover and a reasonable duration.

If you’re leaving, get advice before contacting former clients or colleagues. In many cases, a simple, negotiated understanding about who you will and won’t contact avoids a dispute and keeps your transition smooth.

Key Takeaways

• Restraint of trade clauses are enforceable in Australia when they go no further than reasonably necessary to protect legitimate interests like confidential information, goodwill and workforce stability.
• Reasonableness turns on scope, duration, geography and seniority - and if you add restraints mid‑employment, fresh consideration is typically legally required to make the new promise binding.
• NSW courts can “read down” overbroad restraints under the Restraints of Trade Act 1976; elsewhere, courts won’t rewrite a clause, so precise drafting (including careful cascades) matters.
• Layer protections: use confidentiality, IP assignment, non‑solicit and non‑poach alongside a proportionate non‑compete, and keep your Employment Contract current as roles evolve.
• Implement restraints thoughtfully - clear contracts, sensible access controls, a professional exit process and, where appropriate, garden leave - to reduce risk before disputes arise.
• Most disputes resolve commercially through undertakings. Act promptly, focus on concrete risks, and confirm agreements in a clear settlement document where needed.
