Is a Non-Compete Enforceable in Australia? A Plain-English Guide (2026)

Quick summary: Non-compete clauses in Australia are treated as restraints of trade — presumptively unenforceable unless the employer proves they are reasonable. There is no nationwide statutory ban, but courts across all states scrutinise these clauses closely and strike down a significant proportion of them. New South Wales has a unique statute that lets courts narrow an overreaching clause rather than void it entirely. If your employment contract has one, here's what you're actually looking at.

---

You're about to sign — or have already signed — an employment contract. Somewhere near the end is a clause saying you cannot work for a competitor for 12 months after you leave, anywhere the company operates in Australia. Should you be worried?

The answer depends on which state you're in, what your role was, and whether the clause was drafted within the limits courts actually accept. Many are not.

Quick state reference:

State / Territory	Legal framework	Short answer
New South Wales	Restraints of Trade Act 1976 + common law	Courts can narrow overreaching clauses; enforced more than elsewhere
Victoria	Common law only	Void if unreasonable; no read-down power
Queensland	Common law only	Void if unreasonable; strict test
Western Australia	Common law only	Void if unreasonable
South Australia	Common law only	Void if unreasonable
ACT / NT / Tasmania	Common law only	Void if unreasonable

Restraint of Trade — Australia's Starting Point

Australian courts inherited the English common law doctrine of restraint of trade. Under this doctrine, any clause restricting what a former employee can do after leaving is prima facie void — the starting presumption is against enforcement.

To overcome that presumption, the employer must show three things:

1. A legitimate protectable interest. Trade secrets, confidential client relationships, and the employer's investment in specialised training can qualify. A general desire to retain talent or avoid competition does not.
2. Reasonable terms. The restriction must be no broader in duration, geography, and scope of activity than is reasonably necessary to protect that interest.
3. Not contrary to the public interest. Courts will not enforce a clause that unreasonably prevents a person from earning a living in their chosen field.

All three must be satisfied. A clause protecting a genuine interest with a wildly broad geographic restriction still fails — and outside New South Wales, it will not be enforced even in reduced form.

For a detailed breakdown of what these clauses typically contain, see the non-compete clause explained guide.

What Courts Look At — The Reasonableness Test

Factor	What Australian courts examine
Duration	Is the restriction period proportionate to the interest being protected? 6–12 months is typical; beyond 24 months rarely survives
Geographic scope	Is the territory limited to where the employee actually worked and had client contact?
Activity restriction	Does it prohibit genuinely competing work, or is it a blanket industry ban?
Employee's seniority	Was the employee actually exposed to confidential information or client relationships worth protecting?
Consideration	Did the employee receive anything beyond continued employment for signing a mid-employment restraint?

Courts are most likely to void clauses that apply to junior or mid-level employees with no access to trade secrets, cover states or regions where the employee never operated, use vague language like "any similar business" or "related industry," or were introduced mid-employment without additional compensation.

The NSW Difference — Read-Down Power

New South Wales is the most significant jurisdiction for non-compete law in Australia. The Restraints of Trade Act 1976 (NSW) gives courts a power unavailable anywhere else in Australia: reading down. Instead of declaring a clause entirely void when it fails the reasonableness test, an NSW court can narrow it — enforcing a reduced duration, a smaller territory, or a more limited activity restriction — rather than striking the whole thing.

In practice this means:

• An 18-month restriction might be enforced as 6 months if that is all the court considers reasonable
• A nationwide clause might be enforced as a city-level clause reflecting the employee's actual territory
• A broad industry ban might be narrowed to specific defined competitor categories

This read-down power cuts both ways. Employees in NSW face a higher risk that an overreaching clause is salvaged in modified form. In every other Australian state, an overreaching clause is simply struck — the employer gets nothing.

State-by-State Overview

New South Wales — Statute Gives Courts Flexibility

Employers know NSW courts can read down and often draft more aggressively as a result, expecting courts to trim rather than void. If your contract was signed with an NSW employer, expect the clause to receive close attention — and potentially to be enforced in narrowed form even if the original drafting was excessive.

Victoria — Common Law Only, Strict Reading

Victoria applies the common law test without any statutory supplement. Courts cannot read down — if a clause fails, it fails entirely. Victorian courts have applied a strict approach historically, particularly for non-senior employees. A clause applied to an employee who held no client-facing role or had no access to genuine trade secrets will typically not survive.

Queensland — Employer Must Justify Every Element

Queensland courts apply the same common law test. Enforcement is not uncommon for sales roles with documented client relationships, but courts scrutinise duration and geography closely. A clause without a meaningful territorial limit — "anywhere in Australia" for a Brisbane-based account manager — is unlikely to survive challenge.

Western Australia, South Australia, and the Territories

All remaining states and territories follow the common law reasonableness test with no read-down power. If the clause fails, it falls entirely. For most employees below a senior or specialist level, enforcement in these jurisdictions is uncommon in practice.

Garden Leave in Australia

Garden leave — being paid to stay home during your notice period while being prevented from starting at a competitor — is legal in Australia and increasingly used by employers as an alternative to post-employment non-competes.

Unlike a post-termination non-compete, garden leave runs during the notice period while you remain employed and on full pay. Courts treat it far more favourably because the economic harm to the employee is offset by ongoing salary. Many employers now combine a short notice period with garden leave rights rather than relying on a lengthy post-employment clause.

If your contract includes both, the non-compete period typically starts after the garden leave ends — meaning the total restriction can stack substantially even if each element individually looks proportionate.

What to Do If You Have a Non-Compete in Your Australian Contract

If you're about to sign: Negotiate. Ask your employer to justify the geographic scope, duration, and activity restriction. Many employers will accept a shorter, narrower clause rather than risk losing a hire. Read the full guide on how to get out of a non-compete for specific tactics.

If you've already signed: Look at each element. Is the duration longer than 12 months? Does the geography extend beyond where you actually worked? Does the activity ban cover your entire industry? Any of these can support an argument that the clause fails the reasonableness test.

If you're in NSW: Even an unreasonable clause may be read down rather than voided. If you're planning to join a competitor, get legal advice before acting — you may face an enforceable modified version of what you signed.

If you've received a letter or threat from a former employer: Do not ignore it. An unenforceable clause can still generate injunction applications, cease-and-desist letters, and pressure on your new employer. Consult an employment solicitor in your state before making any public moves.

FAQ: Non-Competes in Australia

Can an Australian employer actually enforce a non-compete? Yes, if the clause meets the reasonableness test: a genuine protectable interest, reasonable duration and geographic scope, and no broader restriction than necessary. Courts look at the employee's actual role and exposure, not just job titles. Many clauses fail at least one of these elements.

What happens to an unreasonable clause outside NSW? It is struck down entirely. Unlike NSW courts, courts in VIC, QLD, WA, SA, and the territories have no power to substitute a narrower restriction. A clause that fails the reasonableness test falls completely — the employer gets no restriction at all.

How long can a non-compete last in Australia? There is no statutory maximum. Courts have upheld restrictions of up to 12 months for senior employees with genuine client or trade secret exposure. Beyond 24 months is rare and almost always fails. For junior or mid-level employees, even 6 months can be difficult to enforce unless the employer identifies specific protectable interests.

Does garden leave count as part of the non-compete period? Usually not. Garden leave runs while you are still employed; a non-compete typically runs from the date employment ends. If both clauses are present, the total restriction can be substantial. Read your contract carefully to confirm whether the non-compete period starts from your last day of active work or from the formal end of employment.

Is a non-compete in a contractor agreement enforceable in Australia? The restraint of trade doctrine applies to contractor agreements as well as employment contracts. Courts tend to apply the reasonableness test even more strictly in a contractor context — independent contractors are expected to work across multiple clients, and a broad industry ban in a contractor agreement faces significant judicial skepticism.

Read It Before You Sign It

Non-competes in Australia are not automatic — they have to survive a reasonableness test that a meaningful proportion of them fail. But an unenforceable clause can still generate legal pressure, injunction applications, and disruption to your new role if a former employer decides to pursue it.

Knowing what you signed — and whether it is likely to hold up — matters before you make any moves.
