Can I Include a Non-Compete Clause in an Australian NDA?

Short Answer: Yes, But Carefully

Australian courts do enforce non-compete clauses, unlike some other jurisdictions that strike them down entirely. However, the courts apply a "reasonableness test" — the restriction must be reasonable in duration, geographic scope, and industry scope. A non-compete that's too broad will be partially or wholly struck down.

What Australian Courts Test for Reasonableness

When you include a non-compete clause in an NDA, a court will ask:

• Is the duration reasonable? 6-12 months? Enforceable. 3-5 years? Depends on the situation. Indefinite? Usually not enforceable.
• Is the geographic scope reasonable? Your suburb/city? Likely enforceable. Your state? Possibly. Australia-wide? Likely too broad. Worldwide? Almost never enforceable.
• Is the industry scope clear? "The person cannot work in [specific industry]" is reasonable. "The person cannot work in any industry" is not.
• Does the employer have a legitimate interest to protect? Trade secrets, customer relationships, or confidential business information count. General competition does not.
• Is there adequate compensation? If you're preventing someone from working, are you paying them during the restriction period? This matters in some cases.

Enforceable Non-Compete Examples

This would likely be enforced:

"The Employee agrees not to work for a direct competitor in the digital marketing industry within Sydney for 6 months after termination of employment, to protect the Employer's proprietary client relationships and business strategies."

Why? Clear duration (6 months), reasonable geography (Sydney), specific industry (digital marketing), and legitimate employer interest.

This would likely be struck down:

"The Employee agrees not to compete with the Employer in any business, anywhere in the world, for 5 years after termination."

Why? Too broad duration (5 years), global geography, and "any business" is vague and overly restrictive.

Duration Guidelines

Australian courts have historically approved:

• 3-6 months: Very likely enforceable if geographic and industry scope are narrow
• 6-12 months: Generally enforceable if reasonable in scope
• 1-2 years: Enforceable in some contexts (e.g., protecting highly sensitive trade secrets or key client relationships) but courts scrutinize closely
• 3+ years: Rarely enforced; courts view this as overly restrictive
• Indefinite: Almost never enforced for employees; sometimes allowed for business sales where confidentiality is truly perpetual

Geographic Scope Guidelines

Likely enforceable:

• Your local city or suburb (e.g., "Melbourne CBD", "Sydney metro area")
• Your state (e.g., "New South Wales", "Victoria")
• Where your actual customers are located

Likely too broad:

• Multiple states without justification
• Australia-wide unless you truly operate nationwide
• International restrictions without a legitimate reason

What Courts Look For: Legitimate Protectable Interest

For a non-compete to be enforceable, you must show you have a "legitimate proprietary interest" to protect. This includes:

• Trade secrets: Proprietary technology, formulas, processes, software code
• Confidential business information: Customer lists, supplier relationships, pricing strategies, financial data
• Customer relationships: The person had close relationships with specific customers who might follow them to a competitor
• Goodwill: The person represented your business to customers and could damage your reputation

NOT legitimate interests:

• General competition ("we don't want them to compete")
• Employee skill and experience (courts don't allow you to prevent someone from using their own skills)
• Vague concerns about "unfair competition"

Non-Compete vs Non-Solicitation

Don't confuse these:

Non-compete: "You can't work for a competitor at all" (broader, harder to enforce)

Non-solicitation: "You can work for a competitor, but you can't solicit our customers or employees" (narrower, easier to enforce)

Australian courts are more willing to enforce non-solicitation clauses because they're less restrictive. If you're unsure whether you need a full non-compete, a non-solicitation clause is often enough and more likely to hold up in court.

Real-World Enforceability Examples

Example 1: Contractor with access to trade secrets

"Non-compete: 12 months, within Sydney, for software development firms."

Likely enforceable because: Duration is reasonable, geography is narrow, industry is specific, and legitimate interest (access to proprietary code).

Example 2: Sales manager with customer relationships

"Non-compete: 6 months, within Australia, for any business in the corporate training industry."

Possibly enforceable because: Duration is short, but geographic scope (Australia-wide) might be challenged depending on where the employee actually worked. Industry scope is reasonably specific.

Example 3: Junior data entry clerk

"Non-compete: 2 years, Australia-wide, for any business."

Very unlikely to be enforced because: The person doesn't have access to valuable trade secrets, the duration is too long, the geographic scope is too broad, and the industry scope is too vague.

Practical Advice for Australian Businesses

Include non-competes when: The person has access to valuable trade secrets, confidential customer lists, or key client relationships. Make them specific, narrow, and time-limited (6-12 months maximum).

Don't bother with broad non-competes: Courts won't enforce them, and they'll damage morale. A narrower, more specific non-solicitation clause is often more effective.

Pay for restrictions: If you want to impose a multi-year non-compete, consider paying the employee a pro-rata salary during the restriction period. This significantly increases enforceability.
