Non-Compete Clauses In Australia: What Employers Need To Know

If you’re building a small business or startup, you’ve probably invested serious time (and money) into your ideas, customer relationships, pricing, systems and people.

So when a key employee leaves, it’s natural to worry about what happens next. Will they take your clients? Use your confidential know-how? Join a competitor and undermine the work you’ve done?

This is where non-compete clauses often come up. They’re common in employment contracts and some contractor arrangements, and they can be a useful part of protecting your business. But in Australia, non-compete clauses are not automatically enforceable just because they’re written into a contract.

In this practical guide, we’ll walk you through what non-compete clauses are, when they’re likely to work, what makes them risky, and how to approach them in a way that’s realistic for a growing business.

What Are Non Compete Clauses (And What Do They Actually Do)?

A non-compete clause (sometimes called a non competition clause or restraint clause) is a contract term that restricts someone from competing with your business after they stop working with you.

In practice, a non-compete clause might try to stop a former employee from:

• working for a competitor;
• starting a competing business;
• providing similar services to your customers;
• operating in a certain location (for example, within 10km of your premises);
• competing for a certain period (for example, 3-12 months after leaving).

Non-compete clauses often sit alongside (and are supported by) other protective clauses, like:

• Confidentiality clauses (to protect sensitive information);
• Non-solicitation clauses (to stop them approaching your clients or staff);
• Non-dealing clauses (to stop them doing business with your clients even if the client reaches out first); and
• IP ownership clauses (to confirm work created on the job belongs to your business).

For many small businesses, a non-solicitation clause can be more practical (and easier to justify) than a broad non-compete. A well-drafted contract often uses a mix of protections rather than relying on one heavy clause.

Where Do Non Compete Clauses Usually Appear?

You’ll most commonly see non-compete clauses in:

• Employment contracts (especially for senior staff, sales roles, technical roles, and client-facing roles);
• Contractor agreements (particularly where contractors work closely with clients or your core systems);
• Business sale agreements (to stop the seller from immediately starting a competing business); and
• Shareholder/founder documents in some situations (for example, exit arrangements and restraint obligations).

For employees, restraints are typically built into the Employment Contract, so it’s clear from day one what’s expected.

Are Non Compete Clauses Enforceable In Australia?

This is the question most business owners really need answered: will it actually hold up?

In Australia, non-compete clauses are generally treated as a restraint of trade. The starting point is that restraints of trade are presumed to be void (not enforceable) unless the business can show the restraint is:

• necessary to protect a legitimate business interest; and
• reasonable in scope (time, geography, activities restrained).

So, yes-non-compete clauses can be enforceable in Australia, but only in the right circumstances and only to the extent they’re reasonable.

It’s also important to know enforceability can turn on state-based differences. For example, in New South Wales, the Restraints of Trade Act 1976 (NSW) can affect how restraints are assessed and may allow a court to read down an unreasonable restraint in some circumstances. In other states and territories, the approach is generally driven by common law principles (and courts may be less willing to “fix” an overly broad restraint).

What Counts As A “Legitimate Business Interest”?

A non-compete clause isn’t there to punish someone for leaving or to stop them earning a living. To justify a restraint, your business usually needs to show it is protecting something real, such as:

• Confidential information (pricing, client lists, supplier terms, strategies, product roadmaps, proprietary processes);
• Customer connections and goodwill (particularly where the employee had strong influence over clients);
• A stable workforce (for example, preventing a departing manager from poaching your team);
• Specialised training you’ve invested in (depending on the role and context).

On the other hand, courts are less likely to support a clause that looks like it’s simply trying to reduce competition in the market, or “lock in” a worker who wants to move on.

What Does “Reasonable” Mean In Practice?

Reasonableness depends on the context, including:

• the employee’s seniority and responsibilities;
• how much client influence they had;
• the nature of your industry (local vs national vs global);
• how quickly confidential information becomes outdated;
• the length of your sales cycle and customer relationships;
• whether the clause is narrowly targeted or overly broad.

What’s “reasonable” for a senior executive with deep access to strategy may be very different from what’s reasonable for a junior employee.

If you’re not sure what’s likely to be enforceable for your situation, it’s worth getting restraint of trade advice before you rely on a clause that may not do what you think it does.

How To Draft Non Compete Clauses That Are More Likely To Work

Non-compete clauses work best when they’re drafted with your real business risks in mind, instead of copy-pasted from a generic template.

Below are practical drafting principles that often make a real difference.

1. Start With The Risk You’re Trying To Prevent

Ask yourself:

• If this person left tomorrow, what exactly could they take or damage?
• Is it clients, confidential information, key staff, or your product know-how?
• How would that harm show up-lost revenue, reputational damage, lost lead pipeline, or competitors undercutting you?

This helps you avoid a “catch-all” restraint that’s broader than necessary (and therefore more likely to be challenged).

2. Keep The Restricted Activities Specific

Clauses that say “you can’t be involved in any competing business” can be too blunt, especially if your business operates broadly or your employee’s role was narrow.

Instead, consider restrictions tied to what the person actually did, such as:

• soliciting or servicing your current clients;
• providing the same service line they delivered for you;
• selling into the same market segment;
• using your confidential systems or methods.

Often, a targeted restraint paired with strong confidentiality obligations gives you a more defensible position.

3. Be Realistic About Time Periods

Time periods should relate to the shelf-life of what you’re protecting.

• If your sales cycle is short and customer relationships turn over quickly, a long restraint can look excessive.
• If your employee managed long-term enterprise accounts, a longer period may be easier to justify.

There’s no magic number that applies to all businesses. The right period depends on your industry, the role, and the risk.

4. Be Careful With Geographic Restrictions

Geography should match where you actually operate (or where the employee could realistically compete).

For example:

• A local clinic might justify a radius-based restraint.
• An online-first startup with customers Australia-wide may need a different approach (and may focus more on customer relationships and confidential info than geography).
• A national business might struggle to justify a clause that restrains “anywhere in the world” unless the role truly had international reach.

5. Consider “Cascading” Restraints

Many Australian restraint clauses are drafted with a “cascading” structure-multiple options for time periods and geographic areas-so if a broader option is found unreasonable, a narrower option might still apply.

This approach can improve enforceability, but it needs careful drafting to avoid ambiguity and ensure the clause operates as intended. It’s also worth noting that “cascading” (and related severance/read-down techniques) don’t work uniformly across Australia: whether a court can sever or read down an unreasonable part of a restraint depends on how the clause is drafted and the laws/cases that apply in the relevant jurisdiction (with NSW often treated differently due to the Restraints of Trade Act 1976 (NSW)).

6. Make Sure The Contract Is Properly Formed And Updated

A restraint clause is only as good as the contract it sits in.

That means your agreement needs to be properly signed, clear, and supported by a valid employment relationship and terms. If you’re changing someone’s role significantly (like promoting them into a senior position), you may need to update the contract and restraint terms to match the new risk profile.

Also, if you’re introducing or strengthening a restraint after someone has already started (for example, asking an existing employee to sign a new contract with tighter non-compete terms), you may need to ensure there’s fresh consideration for the change-such as a promotion, pay increase, bonus, equity, or another clear benefit. Without this, the updated restraint can be harder to enforce.

As a general foundation, it helps to understand what makes a contract legally binding, because enforceability issues can start with basic formation problems (not just the restraint wording itself).

Non Compete Clauses In Employment Contracts: When Should Small Businesses Use Them?

From a business owner perspective, the goal isn’t to restrain every employee “just in case.” The goal is to use the right tool for the right role.

Non-compete clauses are most commonly used where an employee has:

• direct access to key customers and pricing strategies;
• control over sales pipelines and lead generation systems;
• access to product strategy or proprietary tech;
• influence over your team (for example, managers);
• visibility over commercial plans that would genuinely harm you if taken to a competitor.

Non-Compete vs Non-Solicit: Which One Should You Prioritise?

If you’re deciding where to focus, many small businesses get more day-to-day value out of:

• confidentiality obligations (clear, well-defined, and actively enforced); and
• non-solicitation / non-dealing protections (to protect clients and staff relationships).

A non-compete can still be appropriate-especially for senior staff-but it’s often the most likely clause to be contested because it directly restricts someone’s future work.

What About Garden Leave?

Sometimes, instead of (or in addition to) a post-employment restraint, businesses use garden leave during the notice period. This can help reduce risk by keeping the employee away from clients/systems while they are still employed (and still bound by employment duties).

Whether this is suitable depends on the contract terms and your circumstances, but it’s useful to understand garden leave as part of your broader exit strategy for key staff.

Common Mistakes With Non Compete Clauses (And How To Avoid Them)

Non-compete clauses often fail-not because they’re a bad idea in principle, but because they’re drafted or used in a way that doesn’t match the reality of the business.

Here are common pitfalls we see, and what to do instead.

Using The Same Clause For Every Role

A one-size-fits-all restraint across junior and senior roles can be a red flag.

Better approach: tailor the clause based on access, influence and risk. If you have different employment contract templates for different levels, align restraints accordingly.

Drafting Something So Broad It’s Hard To Defend

Clauses that restrain “any competition anywhere” for long periods may feel protective-but they can be harder to enforce.

Better approach: narrow the clause to what you genuinely need to protect (clients, confidential information, or a specific service line).

Relying On A Restraint Without Protecting Confidential Information Properly

If your systems don’t treat key information as confidential in practice (for example, everyone has access, no controls, no clear policies), it can be harder to argue you needed a restraint to protect it.

Better approach: combine good contractual drafting with practical controls (access restrictions, offboarding checklists, returning property, clear confidentiality expectations).

Not Updating Contracts As Your Business Evolves

Startups change quickly. If someone joined when you were pre-revenue and then became your head of sales or product, your old contract may not reflect current risk.

Better approach: update key contracts when roles change, promotions happen, or the business pivots into new markets. If you’re adding or strengthening restraints for an existing employee, consider whether you need fresh consideration (for example, a role change or pay increase) so the update is more likely to stand up.

Forgetting The Bigger Picture: Your Corporate Structure And Founder Arrangements

In early-stage businesses, risk doesn’t only come from employees. Co-founders and shareholders can also leave and create competition issues.

If you have multiple owners, it’s worth ensuring your Shareholders Agreement properly covers exits, confidentiality, and any agreed restraints (where appropriate) so expectations are clear while relationships are good.

What Legal Documents Should Support Your Non-Compete Strategy?

Non-compete clauses rarely work well as a standalone solution. They’re usually most effective as part of a broader set of legal documents and operational practices that protect your business from day one.

Depending on how you operate, you may want to consider:

• Employment Contract: the main place where non-compete clauses are typically included, along with confidentiality, IP ownership and termination provisions.
• Non Compete Agreement: in some cases, a standalone Non Compete Agreement can be used (for example, where you need a dedicated document for a specific senior arrangement).
• Workplace Policies: especially around confidentiality, acceptable use of systems, and handling company information.
• Contractor Agreements: if you use contractors, you’ll want similar protections tailored to that relationship.
• Founder / Ownership Documents: where relevant, a Shareholders Agreement and related documents can reduce risk when an owner exits.

The best set of documents depends on what you do, how you sell, and where your real exposure sits (clients, IP, systems, team, or all of the above).

Key Takeaways

• Non-compete clauses can help protect your business, but in Australia they’re generally only enforceable to the extent they’re reasonable and protect a legitimate business interest.
• A well-drafted restraint should be tailored to the role, with realistic limits on time, geography, and the specific activities being restricted.
• Many small businesses get strong protection by combining confidentiality obligations with non-solicitation/non-dealing clauses, rather than relying on a broad non-compete alone.
• Your contracts should evolve as your team and business grow-especially when someone moves into a more senior, client-facing, or commercially sensitive role. If restraints are added or strengthened mid-employment, consider whether fresh consideration is needed.
• Enforceability can vary depending on jurisdiction and drafting (including whether a court can “read down” or sever an unreasonable restraint, and the specific position in NSW under the Restraints of Trade Act 1976 (NSW)).
• A good non-compete strategy is supported by solid legal documents and practical offboarding processes, not just one clause buried in a contract.
