Cartel Companies and Competition Law in Australia

Competition is healthy - it’s what keeps prices fair and innovation moving. But when competitors coordinate instead of competing, the law steps in. That’s where Australia’s cartel laws come in, and they’re some of the strictest business rules you’ll encounter.

If you run or manage a business in Australia, it’s important to know what counts as cartel conduct, how everyday interactions can create risk, and what you can do to stay compliant. The consequences for getting it wrong can be severe, including heavy fines and even jail time for individuals.

In this guide, we’ll walk through what the law prohibits, practical steps to reduce risk, and what to do if the Australian Competition and Consumer Commission (ACCC) starts asking questions. Our goal is to keep you on the right side of the rules so you can compete with confidence.

What Is A Cartel Under Australian Law?

Under the Competition and Consumer Act 2010 (CCA), a cartel is an agreement (or understanding) between competitors that restricts competition. The law doesn’t just target signed contracts - even informal understandings can be illegal if the effect is to coordinate competition.

Cartel conduct generally includes four types of behaviour between competitors:

• Price Fixing: Agreeing on prices (or pricing methods, discounts, surcharges, credit terms, or price floors/ceilings).
• Bid Rigging: Coordinating responses to tenders (e.g. agreeing who will win, who will submit a cover bid, or who will sit out).
• Market Sharing: Dividing customers, territories, or product lines so you don’t compete with each other in certain areas.
• Output Restrictions: Agreeing to limit production, supply, or capacity to keep prices higher.

These are “per se” prohibitions - they are illegal regardless of whether they actually harm competition in a particular case. The ACCC can bring civil cases, and serious cartel conduct can be prosecuted as a criminal offence.

Penalties are significant. For companies, the maximum civil penalty is the greatest of $50 million, three times the benefit obtained, or 30% of adjusted turnover for the period of the breach. Individuals can face fines and up to 10 years’ imprisonment for criminal cartel offences, alongside banning orders and pecuniary penalties in civil proceedings.

How Do Cartel Risks Arise For Small And Medium Businesses?

Cartel cases aren’t just about multinational giants. Many investigations start in everyday scenarios where competitors cross the line without realising it. Common risk situations include:

• Industry meetings and trade associations: Sharing sensitive pricing, margins, future pricing intentions, or customer lists with competitors.
• Joint tendering and collaborations: Working together on bids without appropriate safeguards can drift into bid rigging or market sharing if roles and information flows aren’t carefully managed.
• Informal chats: Casual “what are you charging?” conversations between sales teams or managers can create an unlawful understanding, even if nothing is written down.
• Price-matching communications: Public announcements about upcoming price rises that are really a signal to competitors to follow suit.
• Shared suppliers or distributors: Using intermediaries to pass on sensitive information between competing businesses.
• Pricing software and algorithms: Coordinated or commonly configured pricing tools that result in aligned prices across competitors.

A practical rule of thumb: never share, receive, or agree about future pricing, customers, territories, or capacity with a competitor. If a competitor tries to start that conversation, stop it immediately, document that you declined, and report it to your legal team.

What Does The Law Prohibit (And Allow)?

Australia’s competition law doesn’t just target explicit cartel agreements. It also captures looser forms of coordination that harm competition. Here’s a quick overview.

Per Se Cartel Conduct

The core cartel prohibitions are straightforward: agreements or understandings between competitors to fix prices, rig bids, share markets, or restrict output are unlawful. There are limited exceptions (for example, where the ACCC has granted an authorisation), but you should never assume an exception applies without advice.

Concerted Practices That Substantially Lessen Competition

You don’t need a formal agreement to breach the law. A “concerted practice” is coordinated behaviour that falls short of an agreement but still reduces competitive uncertainty - for example, exchanging strategic information with a rival in a way that aligns your market conduct. If the effect or likely effect is to substantially lessen competition, it can be illegal.

Other Competition Rules To Keep In Mind

• Misuse of market power: A business with substantial market power cannot engage in conduct that has the purpose, effect, or likely effect of substantially lessening competition.
• Exclusive dealing and third line forcing: Some supply or distribution restrictions can harm competition if they foreclose rivals or customers.
• Resale price maintenance: Suppliers generally cannot dictate minimum resale prices to retailers or prevent discounting.

At the same time, many legitimate collaborations are allowed if they don’t harm competition. The ACCC can authorise certain arrangements that may otherwise breach the law where there is a net public benefit, and there are class exemptions for certain collective bargaining by small businesses and franchisees. If collaboration is important to your strategy, plan it with legal guardrails from day one.

It’s also worth remembering that your marketing and sales practices must comply with the Australian Consumer Law (ACL). For example, avoid false or misleading claims covered by Section 18 and specific prohibitions on misleading statements in Section 29, and steer clear of unconscionable conduct. Competition and consumer rules often travel together in ACCC investigations.

Practical Compliance Steps For Your Business

Good compliance is about prevention. The right systems, training and documents will help your team spot red flags early and respond appropriately.

• Adopt a clear competition compliance policy: Set out do’s and don’ts for staff (especially sales, procurement, and executives) and require annual acknowledgment. Include examples of prohibited contacts with competitors.
• Run regular staff training: Teach your team how to handle competitor approaches, industry meetings, and tenders. Short, scenario-based refreshers can make a big difference.
• Meeting and industry event protocols: Have a script for shutting down sensitive topics, leave the room if needed, and record what happened. Keep agendas and minutes focused on legitimate topics.
• Clean team and information controls: If you’re exploring a joint venture, M&A, or joint tender, segregate teams, limit access to sensitive data, and use confidentiality arrangements appropriately.
• Procurement and tender rules: Centralise oversight of bids. Require declarations that no improper contact with competitors has occurred.
• Dawn raid and investigation readiness: Have a response plan for ACCC site visits and statutory notices. Staff should know who to call and how to preserve (not destroy) documents.
• Speak up culture: Encourage internal reporting and protect whistleblowers. A robust Whistleblower Policy can surface issues early and support lawful cooperation strategies if needed.
• Embed policies into everyday operations: House key rules in your Staff Handbook and maintain an overarching Workplace Policy suite so expectations are clear from onboarding.

For sensitive projects where data-sharing with a competitor may be necessary (for example, during due diligence), use a tightly scoped Non-Disclosure Agreement and implement practical “clean team” protocols. An NDA doesn’t permit anti-competitive conduct, but it’s one control among several to limit unnecessary flows of competitively sensitive information.

What Contracts And Documents Help Manage Competition Law Risk?

Contracts and policies won’t replace sound judgment, but they do set guardrails and accountability. Consider the following documents for your compliance toolkit:

• Competition Compliance Policy: A practical, plain-English policy defining prohibited conduct (price fixing, bid rigging, market sharing) and setting out processes for escalations and approvals.
• Whistleblower Policy: Supports confidential reporting and legal protections for eligible disclosures, which can be crucial in detecting issues early. See Sprintlaw’s Whistleblower Policy.
• Workplace Policy Suite: Houses your compliance standards and training requirements. A documented Workplace Policy framework helps ensure consistency across teams and locations.
• Staff Handbook: A central resource for conduct expectations, including competition law do’s and don’ts. Sprintlaw’s Staff Handbook Package can be tailored to your needs.
• Non-Disclosure Agreement (NDA): Useful for managing confidentiality in legitimate collaborations, M&A discussions and joint projects, alongside clean team rules. Start with a focused Non-Disclosure Agreement and seek advice on information protocols.
• Tender and Collaboration Protocols: Internal rules (and external MOUs) that define scope, information barriers, and approvals for joint tenders or JVs so that coordination stays within lawful bounds.
• Board and Executive Approvals: Clear delegations and paper trails for any conduct that could raise competition issues (e.g. exclusive distribution terms), so decisions are reviewed with legal input first.

If you need structured support, a regulatory compliance lawyer can help design a fit‑for‑purpose compliance program, run training, and review high‑risk contracts or partnerships before you commit.

Investigations, Penalties And Leniency: What Happens If The ACCC Knocks?

Despite best efforts, mistakes and misunderstandings happen. Here’s how the investigation process commonly unfolds and what to do next.

ACCC Information Gathering

The ACCC has strong powers to investigate potential breaches. You might receive compulsory information notices (often referred to as “s155 notices”), requests for interviews, or - in serious cases - an unannounced site visit (“dawn raid”).

Key principles during an investigation:

• Cooperate lawfully: You must not obstruct ACCC officers and you must not destroy or conceal documents. Preserve everything relevant.
• Call your legal team immediately: Have your nominated contacts ready. Ensure staff understand their rights and obligations during interviews.
• Manage communications: Keep a single point of contact for the regulator to avoid inconsistent messaging. Maintain a log of all requests and responses.

Penalties And Personal Exposure

For companies, civil penalties can reach the greater of $50 million, three times the value of the benefit, or 30% of adjusted Australian turnover during the breach period. Injunctions, compliance program orders, corrective notices and damages claims can follow.

For individuals, there is personal civil liability and, for criminal cartel conduct, potential imprisonment of up to 10 years. Directors and managers may also face disqualification orders if they were involved in the contravention.

Leniency And Cooperation

The ACCC and the Commonwealth Director of Public Prosecutions operate an immunity and cooperation regime. The “first in” to report a cartel (and meet the criteria) may receive immunity from civil or criminal proceedings, and others may receive leniency for substantial cooperation.

If you discover potential cartel conduct, act quickly. Preserve evidence, seek immediate legal advice, and consider whether an immunity or cooperation application is in your best interests. Where consumer law issues are also in play, remedies and enforcement can engage the ACL - including actions and remedies contemplated under Section 236.

For tailored guidance on strategy, responses and cooperation options, it’s wise to speak with a consumer and competition lawyer or request an ACL consultation package if ACL risks are also involved.

Key Takeaways

• Cartels are agreements between competitors to fix prices, rig bids, share markets or restrict output - they’re illegal and can attract very serious penalties.
• Everyday scenarios like industry meetings, joint tenders and informal chats can create risk; avoid sharing future pricing, customers, territories or capacity with competitors.
• Beyond per se cartels, concerted practices that substantially lessen competition are also prohibited, and you must comply with related consumer law rules on misleading and unconscionable conduct.
• Build a compliance program with clear policies, regular training, meeting protocols, and strong speak‑up protections - supported by tools like a Whistleblower Policy, Staff Handbook and NDAs for legitimate projects.
• If the ACCC contacts you, preserve documents, coordinate your response through legal counsel, and consider immunity or cooperation options promptly.
• Getting expert advice early can help you collaborate lawfully, reduce risk and focus on competing on the merits.
