What Is a Restraint Period in an Employment Contract in Australia?

Hiring the right people is critical for any small business. But when a key employee moves on, you still need to protect your customers, your confidential information and the goodwill you’ve worked hard to build.

That’s where a restraint period in an employment contract comes in. Used well, it’s a practical tool to reduce the risk of former staff immediately competing with you or soliciting your clients.

In this guide, we explain what a restraint period is in Australia, when it’s appropriate, how long it should be, and how to draft a clause that a court is more likely to enforce. We’ll also walk through common mistakes to avoid and the practical steps to take if you need to enforce a restraint.

What Does “Restraint Period” Mean In Australia?

A restraint period is the timeframe after employment ends during which a former employee agrees not to do certain things that could harm your business. This is commonly part of a broader “restraint of trade” clause in an employment contract.

Typical restraints cover one or more of the following:

• Non-compete: not working for or starting a competing business for a period.
• Non-solicitation: not approaching your customers, suppliers or staff.
• Non-dealing: not accepting business from your customers, whether or not they were solicited.
• Confidentiality: not using or disclosing your confidential information (often without time limits).

The “period” is the duration for which those restrictions apply after the employment ends (for example: 3 months, 6 months, 12 months).

In Australia, restraint clauses are only enforceable to the extent they are reasonably necessary to protect your legitimate business interests. Courts don’t enforce restraints just to prevent competition. They look for sensible, well-targeted protections - particularly for customer connections, confidential information and workforce stability.

When And Why Should You Use A Restraint Of Trade Clause?

Not every role needs a restraint, but many commercial roles do. Consider a restraint clause when an employee will have:

• Regular contact with your customers or prospects (e.g. sales, account management).
• Access to strategic or sensitive information (e.g. pricing, business plans, product roadmaps).
• Influence over staff (e.g. team leaders, managers who could poach colleagues).
• Exposure to trade secrets or unique processes that give your business an edge.

For these roles, a well-drafted restraint can buy you time to bed down relationships with replacement staff, refresh your sales pipeline, and reduce the risk of an immediate hit to revenue when someone leaves.

Where roles are junior, routine or have little customer contact, a narrow non-solicit coupled with strong confidentiality obligations may be enough.

If you’re unsure how far you can go for a particular role, it can be useful to obtain tailored Restraint of Trade Advice before you hire or promote someone into a sensitive position.

How Long Should The Restraint Period Be?

There’s no one-size-fits-all answer. Reasonableness depends on your business, the role and the market. However, some practical guidelines apply.

What Courts Consider

• Legitimate interests: Are you protecting confidential information, customer relationships or staff stability?
• Scope of activities: Is the restraint limited to the actual competitive activities the employee could perform, given their skills and role?
• Geographic area: Is the area limited to where you genuinely operate and where the employee had influence?
• Duration: Is the period no longer than necessary to protect your interests (e.g. time to transition accounts)?
• Seniority and access: Senior, client-facing or strategic roles can justify longer, wider restraints than junior roles.

Common Ranges In Practice

As a broad sense-check (not a rule), many Australian courts are more comfortable with shorter, targeted restraints:

• Non-solicit/non-deal of customers: often 3-12 months, depending on sales cycles.
• Non-compete: often 3-6 months for mid-level roles; up to 12 months for senior executives where justified.
• Staff non-solicit: commonly 6-12 months to protect team stability.

The right period for you depends on how long it takes to replace the employee, transition customers and ensure confidential information diminishes in value.

Use “Cascading” Restraints

To improve enforceability, many contracts use cascading restraints (also called “step” restraints). This sets out multiple combinations of time periods, areas and activities, in descending order (for example, 12, 9, 6, 3 months; Australia, state, city). If a broader restraint is found unreasonable, a court can “read down” to the next reasonable step rather than strike the whole clause.

Are Restraint Periods Enforceable?

They can be - if they’re reasonable and carefully drafted. A restraint will not be enforced if it’s broader than necessary or simply aimed at stopping competition.

Drafting Principles That Help

• Tailor the clause to the role. Avoid boilerplate wording that’s the same for a junior assistant and a sales director.
• Define the business and competitors clearly, rather than “any business in any industry”.
• Limit the geography to where the employee actually had influence (for example, the states they serviced).
• Use cascading combinations of period, area and activities.
• Ensure the clause sits within a robust, signed Employment Contract that spells out duties, confidentiality and IP ownership.

Consider Garden Leave

Another practical tactic is keeping a departing employee away from the market during their notice period by placing them on garden leave. They remain employed (and paid) but don’t attend work while you transition clients and limit access to live information. Garden leave often complements, rather than replaces, a post-employment restraint.

Changes During Employment

If a restraint is agreed at the start and the role later becomes significantly more senior, you may want to refresh the restraint (for example, on promotion or bonus grant) so it remains appropriate to the new level of risk. A new contract or deed, properly executed, can help avoid arguments about reasonableness where responsibilities have grown.

How Do You Draft A Balanced Restraint Clause?

A well-structured restraint focuses on what you’re legitimately trying to protect. Here’s a practical approach you can tailor for each key role.

1) Identify Your Legitimate Interests

Be explicit about what you need to protect. Common interests include confidential information, client connections and workforce stability. If the role holds unique knowledge or relationships, note this so the clause can reflect it.

2) Map The Activities To Restrict

Draft the restraint around the activities that would realistically cause harm. If the person is a sales lead, a non-solicit and non-dealing restraint may be more defensible than a wide non-compete. For highly strategic executives, a tailored non-compete can sometimes be justified.

3) Choose Sensible Geographies

Restrict only the areas where you actually do business and where the employee had influence. If you service NSW and QLD, it’s harder to justify an Australia-wide restraint for a mid-level role focused on Sydney.

4) Set A Reasonable Period

Pick the shortest period that still protects your interests. Add a cascading set of periods (for example 12, 9, 6, 3 months) so there’s a reasonable fall-back if a court trims the clause.

5) Consider Role-Specific Variations

For sales roles, focus on customer non-solicit and non-deal, with geography defined by the person’s territory. For tech or product roles, focus on confidentiality and targeted non-solicit of staff or partners. For executives, consider a narrower non-compete backed by stronger confidentiality.

6) Pair With Other Protections

• Confidentiality: A strong confidentiality clause and, where appropriate, a stand-alone Non-Disclosure Agreement when sharing information with third parties.
• IP ownership: Clear IP provisions so work product is owned by the business.
• Notice and garden leave: Use notice provisions and garden leave to reduce risk at exit.
• Post-employment obligations: Remind departing staff of their restrictions during offboarding.

Common Pitfalls Employers Should Avoid

Overreaching On Scope

Broad, catch-all restraints (for example, “no work in any capacity for any competitor anywhere in Australia for 2 years”) are likely to be challenged. Aim for precision: define your “business”, limit the activities to real risk areas, and choose a realistic area and period.

Using The Same Clause For Every Role

Courts assess reasonableness role-by-role. A junior admin assistant doesn’t justify the same restraint as your head of sales. Calibrate the clause to the level of risk and influence.

Not Updating On Promotion

When responsibilities change, update the restraint and have it properly accepted in writing. Don’t rely on a stale clause from a prior, junior role.

Weak Confidentiality And IP Provisions

Restraints work best alongside strong confidentiality and IP terms. Make sure your core agreement is a current, well-drafted Employment Contract with clear confidentiality and IP ownership provisions.

Poor Offboarding Hygiene

Risk spikes when access controls are slow and messaging is unclear. On resignation, promptly remove access to systems, collect devices, remind the employee of their obligations and issue appropriate termination documents. If the risk is high, consider garden leave during notice.

Enforcing A Restraint: Practical Steps For Employers

Act quickly and proportionately. The early days after a resignation or departure are critical.

1) Assess The Risk And Gather Evidence

Identify what exactly you’re protecting (clients, staff, tech, strategy). Preserve evidence of potential breaches (emails, CRM exports, LinkedIn updates, client reports). Keep this focused and lawful.

2) Remind And Request Undertakings

Send a professional letter reminding the former employee of their obligations and requesting written undertakings not to breach their restraint or confidentiality. Often, clear communication resolves issues without litigation.

3) Engage With The New Employer (Where Appropriate)

Where you have evidence of risk, a measured note to the new employer may help set boundaries. Keep it factual. Overreach can backfire, so get legal guidance on tone and content.

4) Consider Legal Action For Serious Breaches

If harm is imminent or ongoing, you can seek an injunction to stop the conduct, plus damages if loss has occurred. Timing matters: courts are more willing to intervene early while the restraint still has value.

A pragmatic option in many cases is negotiating a practical resolution - for example, a narrower restraint period, a client carve-out, or role limitations with the new employer - formalised in a separation agreement or deed.

Before taking steps that escalate the dispute, it’s wise to get tailored Restraint of Trade Advice so you understand the strength of your clause and the likely outcomes.

Complementary Tools To Protect Your Business

Restraints are one part of a broader protection strategy. Consider these additional levers:

• Employment contracts: Up-to-date Employment Contract templates for each role type, with tailored restraints and strong confidentiality/IP terms.
• Confidentiality agreements: Use an Non-Disclosure Agreement with contractors, candidates or prospective partners before sharing sensitive information.
• Equity incentives: If you use an Employee Share Option Plan, ensure the plan rules and offer documents address leaver scenarios and post-employment conduct.
• Policies and training: Educate staff about confidentiality and acceptable use of information. Clear policies reduce accidental risk and support enforcement.
• Exit protocols: Consistent offboarding checklists, access removal, asset returns, and a reminder letter that sets out post-employment obligations.
• Garden leave: Strategic use of garden leave during notice to allow time for client transition and information “cooling off”.

Key Takeaways

• A restraint period is the post-employment timeframe in which a former employee agrees not to compete, solicit or deal with your customers, or poach staff.
• In Australia, restraints are only enforceable if they are reasonable and protect legitimate interests like confidential information and client relationships.
• Pick the shortest period, tightest geography and most targeted activities that still protect your business, and use cascading steps to improve enforceability.
• Restraints work best alongside strong confidentiality, IP ownership, clear notice provisions and, where appropriate, garden leave.
• Tailor restraints to the role, refresh them on promotion, and maintain solid offboarding processes to reduce risk at exit.
• If a breach is likely, act promptly: gather evidence, seek undertakings, and consider injunctions for serious risk - get tailored Restraint of Trade Advice early.
