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

When a valued team member moves on, you don’t want your client list, know-how or strategy walking out the door with them. That’s why many Australian employers consider using a non-compete clause (also called a restraint of trade) in their employment contracts.

But here’s the catch: in Australia, non-compete clauses are only enforceable if they’re reasonable and necessary to protect your legitimate business interests. Overly broad or generic restraints will likely be struck down.

In this guide, we’ll unpack how non-compete clauses work in Australia, when they make sense, what “reasonable” looks like in practice, and how to draft a restraint that’s more likely to stand up if you ever need to rely on it. We’ll also cover practical alternatives and enforcement tips so you can choose the right approach for your business.

What Is A Non-Compete Clause (Restraint Of Trade) In Australia?

A non-compete clause is a contractual term that restricts an employee from engaging in competitive activities after their employment ends. It sits within a wider group of “restraint of trade” clauses that can also include:

• Non-solicitation of your clients, customers or suppliers.
• Non-poaching of your employees and contractors.
• Non-dealing with your clients (even if the client approaches them).
• Confidentiality obligations and IP ownership/assignment.
• Notice and garden leave (keeping someone out of the market while they work out their notice on pay) - see more on garden leave.

In Australia, the term “non-compete” is often used interchangeably with “restraint of trade.” Courts generally prefer the narrowest restraint necessary to protect your business. That means a tailored non-solicit or non-dealing clause will often be more enforceable than a blanket non-compete that tries to stop someone working in their industry altogether.

Are Non-Compete Clauses Enforceable In Australia?

Yes - but only if the clause is reasonable and goes no further than necessary to protect a legitimate business interest. By default, restraints are presumed void at common law, and the onus is on the employer to show they’re justified.

What counts as a legitimate business interest?

Typical interests include protecting your confidential information and trade secrets, customer and supplier relationships, workforce stability, and the goodwill you’ve built up (especially if the employee is the “face” of your brand to key clients).

What makes a clause “reasonable”?

Court decisions look at reasonableness in terms of:

• Scope of activities: exactly what is being restrained (e.g. working for a direct competitor in a similar role, starting a competing business, soliciting specific customers).
• Geographic area: where the restraint applies (suburb, city, state, national). Tie it to your actual market footprint.
• Duration: how long it lasts. Shorter is safer. Common ranges are 3-12 months for employment restraints, sometimes longer for very senior roles.
• The employee’s role and access: seniority, access to sensitive information, influence with clients, and the industry context all matter.
• Consideration: what the employee received for agreeing (usually employment itself; if introduced later, further benefit is wise).

Many Australian contracts use “cascading” restraints: a list of decreasing durations and areas separated by “or” (e.g. 12 months/6 months/3 months; Australia/NSW/Sydney). Courts can then “read down” to a reasonable combination instead of voiding the clause entirely.

Does Fair Work ban non-competes?

No. The Fair Work Act doesn’t specifically prohibit non-compete clauses. However, your obligations under awards and enterprise agreements still apply, and restraints can’t be used to undermine minimum employment standards. Reasonableness remains the key test.

State differences to know

In New South Wales, the Restraints of Trade Act 1976 gives courts extra flexibility to modify (“sever”) restraints to make them reasonable. Other states rely on the common law; the core principles are similar, but you don’t get the same statutory “safety net.” Either way, tailoring the clause up-front is still best practice.

When Should You Use A Non-Compete (And When Not To)?

A non-compete can be useful where the risk to your business is real and specific - not just theoretical. For example:

• Senior executives who set strategy, pricing, product roadmaps or have significant market knowledge.
• Sales leaders and account managers with deep client relationships and influence.
• Specialists and product roles with access to trade secrets or unique processes.

In these scenarios, a carefully drafted restraint can give you time to solidify client relationships and protect your competitive edge after a resignation.

On the other hand, broad non-competes for junior or operational roles (with limited access to sensitive information) are unlikely to be reasonable. In those cases, rely on robust confidentiality, non-solicitation and IP clauses instead of trying to prevent someone working in their field.

How To Draft A Reasonable Non-Compete Clause

Getting the drafting right is critical. If a restraint is too broad, you risk it being unenforceable. If it’s too narrow, it may not protect what really matters. Consider the following practical tips.

1) Be clear on the interest you’re protecting

Identify exactly what you’re safeguarding: client relationships in a named portfolio, supplier networks, confidential pricing models or product plans, or workforce stability. The protection should match the risk.

2) Narrow the activities being restrained

Define “competitive activities” precisely. Restraining someone from “any work in the industry” is risky. A more targeted restraint might cover working for a direct competitor in a similar role, starting a business that offers the same core services, or soliciting specific named clients.

3) Choose a sensible geographic area

Tie the geography to where you actually operate or where the employee can influence customers. If your client base is within Greater Melbourne, a national restraint will be hard to justify. If you genuinely sell nationally, a broader area may be reasonable.

4) Set a proportionate duration

Ask: how long do we really need to protect this interest? For most employment restraints, 3-12 months is more common, with the longer end reserved for very senior roles. Multi-year restraints are typically reserved for a sale-of-business context (where the seller is paid for goodwill).

5) Use cascading restraints

Draft a tiered list of durations and areas. This gives a court options to “read down” the clause to a reasonable combination if needed, improving enforceability.

6) Put it in the right contract, at the right time

The restraint should sit within a well-drafted Employment Contract, alongside confidentiality, IP ownership and post-employment obligations. If you’re adding a restraint after employment has started, consider whether additional consideration is needed and follow a proper change process - see guidance on changing employment contracts.

7) Get tailored legal advice

Every role and industry is different. It’s wise to work from a template that’s built for Australian law and then tailor it. If you need help drafting or reviewing, our team can prepare a non-compete agreement and provide restraint of trade advice that fits your risk profile and growth plans.

Enforcing A Non-Compete: Practical Steps For Employers

Most restraint issues can be resolved commercially if you act quickly and proportionately. A measured approach often protects your business without escalating costs.

1) Act early and gather evidence

As soon as you’re aware of a potential breach, collect evidence. That might include resignation dates, contract terms, client communications, access logs, or proof of the new role and employer’s activities. Keep your language factual and avoid allegations you can’t substantiate.

2) Send a firm but reasonable letter

Your lawyer can write to the ex-employee (and in some cases, the new employer) setting out the restraint, the risk to your business, and what you want them to stop doing. Often, this results in an undertaking not to solicit clients for a defined period.

3) Consider negotiation and interim solutions

Practical compromises might include narrowing the restraint, carving out certain clients, or agreeing to a shorter duration. Courts expect parties to behave reasonably, and a negotiated outcome may protect your key interests faster than litigation.

4) Injunctions and court action

If the risk is acute (e.g. active targeting of your top clients), you can seek an injunction to stop the conduct while the dispute is decided. This is a serious step that requires strong evidence and cost/benefit analysis.

5) Don’t forget garden leave

If your contract allows it, placing a resigning employee on paid garden leave during their notice period can be an effective way to keep them out of the market temporarily while you transition clients and knowledge. You can read more about garden leave and how it works in Australia.

Alternatives And Complements To Non-Competes

Often, a narrower restraint plus strong confidentiality and IP terms will give you better real-world protection than a broad non-compete alone.

• Confidentiality and IP clauses: Make sure your contract clearly states that business information, trade secrets, code, designs and data remain confidential, and that IP created in the course of employment belongs to your business.
• Non-solicit and non-dealing: Prevent targeted approaches to your clients and staff, and block ex-employees from doing business with named customers for a defined time.
• NDAs with third parties: When contractors, partners or bidders see sensitive information, use a standalone Non-Disclosure Agreement to lock down confidentiality.
• Notice and garden leave: Keep outgoing employees away from client files and strategy while they work out their notice.
• Onboarding and offboarding: Reinforce obligations at both ends. Collect devices, revoke access, and remind departing staff of their post-employment duties in writing.

It’s common to combine these measures with a targeted non-compete for senior roles. The goal is layered protection that’s proportionate to the risk.

State-Specific Notes: NSW, Victoria And Queensland

NSW: The Restraints of Trade Act 1976 (NSW) allows courts to read down and enforce a restraint to the extent it’s reasonable. Cascading clauses work well in NSW for this reason.

Victoria and Queensland (and most other states): The common-law test applies. Courts will assess the reasonableness of the restraint at the time the contract was entered, considering the role, industry and business interests. There’s no equivalent statute to “fix” an overbroad clause, so careful drafting is especially important.

Across all states and territories, the themes are consistent: identify the interest, tailor the scope, and keep durations proportionate. If your team and clients are spread nationally, your drafting should reflect where the employee actually had influence.

FAQs For Employers

Is a non-compete clause enforceable in Australia?

It can be, if it’s reasonable and protects a legitimate business interest such as confidential information, client connections or goodwill. Overly broad restraints are likely to be struck down or read down.

How long can a non-compete last?

For employment contracts, 3-12 months is common, depending on seniority and the sensitivity of information. Longer periods are more typical in a sale-of-business context, where the seller is paid for goodwill.

What if I’m hiring someone who has a non-compete?

Ask for a copy of their restraint and get advice before they start. You may need to tailor their role, clients and territory to avoid inducing a breach, or agree on guardrails for the transition period.

How do people “get around” a non-compete in Australia?

Courts won’t enforce a restraint that goes beyond what’s reasonably necessary. Employees sometimes argue the clause is too broad, or that they aren’t competing in the restrained area or role. This is why precise drafting and proportionate scope are essential for employers.

Can I restrain contractors and casuals?

Yes, restraints can also be used in contractor agreements. Reasonableness still applies, and the scope should reflect the contractor’s access to clients and confidential information.

What To Include In Your Employment Contracts

A strong employment contract sets up your restraint strategy for success. At a minimum, consider including:

• Confidentiality: Clear, long-lasting obligations that continue post-employment.
• IP ownership: Ensure IP created in the course of employment belongs to your business.
• Non-solicit and non-dealing: Restrict approaching or doing business with named clients and staff for a defined period.
• Non-compete: A tailored restraint for senior or sensitive roles, with cascading durations and areas.
• Notice and garden leave: The ability to keep a departing employee away from client work during notice.
• Contract variation process: If you may need to update restraints later, set out how changes will be agreed (and consider the need for additional consideration for mid-employment changes).

If you’re refreshing your templates, our team can prepare an Employment Contract tailored to your roles and risk profile, and help with non-compete clauses that align with Australian case law. If you’re updating existing agreements, it’s important to use a fair, consultative process - see our guide on changing employment contracts - and seek targeted restraint of trade advice where needed.

Key Takeaways

• Non-compete clauses are enforceable in Australia if they’re reasonable and protect a legitimate business interest like confidential information, client relationships or goodwill.
