How Does a Non-Compete Agreement Work?

In Short

Non-compete agreements prevent a person from competing with your business for a defined time and geographic area after employment or engagement ends. Australian courts will only enforce these clauses if they protect a legitimate business interest and are reasonable in scope. If the restraint is too broad, a court may refuse to enforce it.

Tips for Businesses

Ensure any non-compete clause clearly identifies the business interest you are trying to protect, such as confidential information or client relationships. Keep the restriction proportionate by limiting the duration, geographic area and scope of activities. Review employment contracts carefully so restraints reflect the employee’s role, responsibilities and access to sensitive information.

Summary

This article explains how non-compete agreements work for businesses in Australia and when courts may enforce them. It was prepared by LegalVision’s business lawyers, and provides a practical overview of restraint clauses and the legal requirements that apply under Australian law.

A non-compete agreement is a contractual agreement that prevents a person from competing with your business for a defined period and within a defined geographic area. Businesses commonly use these restraints in employment areas, although you may use a separate non-compete agreement. This article outlines the legal requirements for non-compete enforceability, including the need to protect a legitimate business interest.

How Do Non-Compete Agreements Work?

Your business may enter a non-compete agreement with an employee, contractor or other commercial party. The clause aims to protect your business when the relationship ends. In other words, it restricts the former contractor or employee from engaging in activities that directly compete with your business.

You should provide a non-compete before an individual starts work or engagement. If you introduce the restraints after an employee starts their work, you will not be able to enforce the clause. However, if you provide additional consideration, such as a promotion or benefit, exceptions may apply.

Australian courts closely scrutinise non-compete clauses. If a restraint goes further than necessary to protect your business, the court may refuse to enforce it.

When are Non-Compete Clauses Enforceable in Australia

Under Australian common law, courts treat non-compete clauses as restraints of trade. As a result, the clause will only be enforceable if it protects a legitimate business interest and remains reasonable in scope. You must show that the restraint protects something genuinely valuable to your business. 

Courts will not enforce a clause that simply prevents a former employee from starting a new job or earning a living. 

In addition, the clause must form part of a valid contract supported by consideration. In an employment contract, the employees’ salary and other employment benefits usually satisfy this requirement.

What Legitimate Business Interests Can a Non-Compete Protect?

Courts will only enforce restraints that protect identifiable and legitimate business interests. These interests must be specific to your business and vulnerable to misuse after the relationship ends.

Some examples include:

  • trade secrets;
  • confidential information;
  • specialised training investments; or 
  • established client relationships

Courts will not enforce restraints that simply prevent a formal employee from using general skills and experience gained during employment.

The Reasonableness Test for Non-Compete Clauses

The restraint must not be broader than reasonably necessary to protect legitimate business interests. Courts assess several factors when assessing this.

Duration of the Restraint

The restraint period must remain proportionate to the risk faced by your business. Courts more commonly enforce shorter restrictions.

For many roles, shorter periods between three and twelve months are commonly enforceable. Senior executives may face extended restraints of twelve and twenty-four months where their roles give access to highly sensitive information or strong client relationships.

Geographic Scope

The restrictions must apply to locations where the employee actually worked or had contact with customers. Courts rarely apply nationwide or international restraints unless the employee’s role genuinely covered those areas.

Roles and Responsibilities

The scope must reflect the employee’s position, responsibilities and access to confidential information within your company. In practice, restraints more commonly appear in contracts for senior employees or employees earning above the high income threshold, as these roles are more likely to involve access to confidential information, strategic knowledge or key client relationships.

If any part of the restraint is unreasonable, the court may refuse to enforce the clause. For this reason, it is important that non-compete terms in an employment contract or a separate non-compete agreement are carefully drafted.

Key Takeaways

A non-compete agreement prevents a former employee, contractor or business partner from competing with your business after the relationship ends. It is important that the protections afforded to a party’s business by a non-compete agreement are reasonable the agreement may be unenforceable. Your business should carefully draft non-compete clauses to ensure they remain proportionate and legally enforceable.
