What Is An Anti‑Competitive Clause? A Practical Guide For Small Businesses In Australia

Running a small business in Australia is exciting, but contracts can sometimes feel like a maze. If you’ve been presented with terms that seem to box you in-like stopping you from selling to certain customers, fixing your prices, or restricting you from working in your industry-there’s a good chance you’re dealing with “anti‑competitive” clauses.

Some restrictions are normal and can be enforceable. Others may breach competition law, be unfair to small businesses, or simply go further than necessary and end up unenforceable.

In this guide, we’ll explain what anti‑competitive clauses are, how Australian law treats them, where they commonly appear, when a restraint might be lawful, and the practical steps you can take to protect your business before you sign.

What Is An Anti‑Competitive Clause?

An anti‑competitive clause is a contractual term that restricts how a business competes. It can control who you can deal with, where you can operate, how you price your products, or what you can do after a relationship ends.

Common examples include:

• Non‑compete restraints that limit you from operating a similar business for a period or in a defined area.
• Exclusive dealing obligations that require you to purchase or supply exclusively through a single provider or channel.
• Resale price maintenance (for example, setting minimum prices a reseller must charge).
• Market sharing arrangements that carve up customers, territories, or product lines between competitors.

These clauses sit on a spectrum. Some are ordinary commercial protections (e.g. keeping trade secrets confidential). Others are serious competition risks (e.g. agreements with competitors to fix prices). Understanding the difference is essential before you sign-or seek to enforce-these terms.

How Australian Law Treats Anti‑Competitive Clauses

Australia’s competition framework is mainly set out in the Competition and Consumer Act 2010 (Cth), enforced by the Australian Competition and Consumer Commission (ACCC). The law focuses on whether conduct substantially lessens competition, with some conduct banned outright.

Cartel Conduct: Per Se Prohibitions

Agreements between competitors to fix prices, restrict output, rig bids or share markets are called “cartel conduct” and are prohibited outright. You don’t need to prove actual market harm-these arrangements are unlawful on their face. Serious civil penalties can apply to businesses involved, and individuals may also face liability in some circumstances.

Exclusive Dealing (Including Third Line Forcing)

Exclusive dealing covers a wide range of “you must deal with me (or not deal with them)” conditions. Since law reforms, most forms of exclusive dealing-including third line forcing-are assessed on whether they have the purpose, effect or likely effect of substantially lessening competition. Many exclusivity terms are legitimate in context, but the broader and longer the restriction, the higher the risk it could impede competition.

Resale Price Maintenance

Suppliers generally must not require or pressure resellers to sell at or above a minimum price. This is a specific prohibition because it interferes directly with price competition to consumers. Recommended retail prices (RRPs) can be fine if they are genuinely recommendations and not enforced.

Misuse Of Market Power

Businesses with substantial market power must not engage in conduct that has the purpose, effect or likely effect of substantially lessening competition. If a dominant supplier uses its position to impose harsh restrictions or “bundle” terms that squeeze rivals, this can raise misuse of market power issues.

Unfair Contract Terms Now Attract Penalties

Separate to competition prohibitions, the Australian Consumer Law (ACL) protects small businesses from unfair terms in standard form contracts. From late 2023, proposing, using or relying on unfair contract terms can attract civil penalties, in addition to such terms being void. Small business coverage has also expanded (generally capturing businesses with fewer than 100 employees or under $10 million annual turnover), meaning more SMEs benefit from these protections under the Australian Consumer Law.

It’s important to separate two ideas:

• Competition law bans (like cartel conduct and resale price maintenance) regulate market-wide behaviour.
• Contract law and unfair terms rules regulate the fairness and enforceability of specific clauses in agreements, especially standard form contracts offered to small businesses.

Penalties and remedies depend on the conduct, who’s involved, and the legal basis (competition prohibition vs unfair contract term), so it’s not automatically the case that “both parties” will be fined for an anti‑competitive clause-liability turns on the facts.

Common Places You’ll See These Clauses (And What To Watch For)

Anti‑competitive terms can appear in many commercial agreements. Here are typical hotspots and red flags to consider.

Franchise Agreements

Franchising often involves non‑compete and territorial protections. Reasonable restraints can be enforceable, for example preventing a franchisee from opening a near-identical store down the road immediately after exit. But nation‑wide or multi‑year restraints with no clear link to legitimate interests may be overreaching.

Supply And Distribution Agreements

Exclusive supply territories, minimum purchase obligations, or exclusive dealing promises are common in distribution chains. Assess the scope (products, channels), duration, and exit rights. Consider whether a strict exclusivity could prevent you from switching if quality or price changes. A well‑drafted Supply Agreement can balance commercial certainty with competition law compliance.

Retail & Resale Relationships

Be careful with price clauses. Setting a “recommended” price is permissible if truly optional; setting minimum resale prices, or threatening consequences for discounting, risks resale price maintenance issues.

Commercial Leases

Shopping centres sometimes include “use” restrictions to manage tenant mix. These are common, but watch for terms that prevent you from operating reasonable ancillary lines of trade or expanding into nearby centres post‑lease.

Employment & Contractor Arrangements

Post‑employment restraints and non‑solicitation clauses appear frequently. At common law, a restraint must go no further than reasonably necessary to protect legitimate interests (like confidential information or client connections). Overly broad “industry‑wide” bans are vulnerable. If you’re drafting or reviewing these terms, targeted restraint of trade wording is key.

Shareholder & Confidentiality Documents

Co‑founder documents often include non‑compete and non‑poach terms. These may be appropriate in scope, especially where owners have deep access to sensitive know‑how. Use a focused Non‑Disclosure Agreement to protect confidential information so you don’t need to rely on broader restraints, and make sure any Shareholders Agreement keeps restraints proportionate.

Are Restraints Ever Enforceable? Reasonableness Vs Illegality

Not every restraint is unlawful. Australian courts recognise that some restrictions are necessary and reasonable to protect legitimate interests, particularly outside of competitor‑to‑competitor arrangements.

Key questions to ask:

• What interest is the clause protecting (e.g. trade secrets, goodwill, investment in training)?
• Is the scope limited to what’s reasonably necessary-by time, geography and subject matter?
• Does it risk substantially lessening competition in the broader market (beyond the parties’ relationship)?
• Is the term appearing in a standard form contract offered to a small business, such that unfair term penalties could apply?

For example, a six‑month non‑compete limited to a local trading zone may be defensible, while a five‑year nationwide ban is unlikely to be enforceable unless there are exceptional facts. Similarly, an exclusive distributorship in a niche channel for a short term may be commercially justifiable, but rigidity across all channels for multiple years may raise competition concerns.

If you need protection, consider designing your contracts around targeted confidentiality, non‑solicit, and IP protections first. Then, where a non‑compete is still genuinely required, keep the restraint tightly tailored. In many cases, a clear, balanced Service Agreement that addresses confidentiality, IP ownership, and client non‑solicit obligations will do more heavy lifting than a sweeping non‑compete.

Practical Steps To Protect Your Small Business

You don’t need to become a competition lawyer to manage this risk. A few practical habits can go a long way.

1) Read For Substance, Not Just Labels

Don’t be distracted by headings like “Confidentiality” or “Territory.” Focus on what the clause actually restricts. Ask yourself: Does this term limit who I can sell to, what I can charge, or how I can operate during or after the contract?

2) Watch The “Big Three” Dimensions: Time, Area, Scope

Reasonable restraints are narrowly targeted. If a proposal feels broad, try to confine it by:

• Time: reduce months or years, include review points.
• Area: limit to a defined local catchment or channel rather than nationwide.
• Scope: focus on specific products, services or clients-not the entire industry.

3) Separate Competition Risks From Fairness Risks

Cartel conduct (between competitors) and resale price maintenance are competition law red flags. Unfair terms in a standard form contract (especially with a small business counterparty) raise separate ACL risks, including penalties. Keeping these categories straight helps you respond appropriately-competition bans require re‑drafting at a fundamental level; unfair terms often need proportionality and transparency fixes under the ACL.

4) Use Purpose‑Built Documents

Often, anti‑competitive risk creeps in when one clause is used to solve many problems. Instead of one sweeping restraint, use the right tool for each job:

• Non‑Disclosure Agreement to protect confidential information.
• Service Agreement to set clear deliverables, IP ownership and non‑solicit rights.
• Supply Agreement with proportionate exclusivity and practical exit rights.
• Shareholders Agreement with targeted founder protections that don’t overreach.

5) Build Negotiation “Fallbacks”

If a counterparty insists on a restraint, propose a scaled set of alternatives: e.g. non‑solicit first; if a non‑compete is necessary, offer graduated time/area options the other party can choose from. This shows you’re protecting legitimate interests without over‑reaching.

6) Keep A Commercial Justification File

Record why a restraint is included-what you’re protecting, why the time/area is needed, and what alternatives were considered. If the term is challenged later (or reviewed by a regulator), having contemporaneous notes helps show reasonableness and good faith.

7) Sense‑Check Pricing And Communications

Never agree with competitors on prices, discounts, or customers. Avoid “we won’t undercut each other” conversations. Even a casual email can create evidence of an understanding. If a supplier tries to enforce minimum retail prices, that’s a signal to seek advice promptly.

8) Use A Contract Health Check Before You Sign

A quick, focused Contract Review can flag enforceability problems, unfair terms risks, and competition law concerns early-when it’s easiest to fix them. Getting this done before signature gives you leverage to negotiate sensible changes.

9) Keep An Eye On Law Reform

There is ongoing policy attention on post‑employment non‑compete restraints. While no blanket ban currently applies, scrutiny is increasing. Building your protections around confidentiality, non‑solicit and IP today is a future‑proof approach.

10) Act Early If You’re Challenged

If a counterparty alleges your clause is anti‑competitive, respond constructively. Sometimes a targeted amendment resolves the issue. If the ACCC makes contact, seek advice immediately-timely cooperation and rectification can make a material difference to outcomes.

Key Takeaways

• Anti‑competitive clauses are contract terms that limit competition; some are outright illegal (like cartel conduct and resale price maintenance), while others turn on whether they substantially lessen competition.
• Unfair contract terms rules under the ACL now carry penalties when used in standard form contracts, with expanded protections for small businesses.
• Restraints can be enforceable if they’re reasonably necessary to protect legitimate interests and are tightly scoped by time, area and subject matter.
• Watch high‑risk hotspots such as franchise, supply/distribution, resale price terms, leases, and employment or founder restraints.
• Use targeted tools-confidentiality, non‑solicit, IP ownership and well‑drafted commercial agreements-instead of sweeping non‑competes.
• Document your commercial justification, negotiate proportionate terms, and get an early contract health check before you sign.
