Cartel Provisions Explained For Businesses In Australia

If you run a small business or startup, you’re probably focused on growing sales, finding the right suppliers, and staying competitive in a crowded market.

What can catch people off guard is that some “normal” business conversations (especially with competitors) can cross a legal line quickly. That’s where Australia’s cartel provisions come in.

In Australia, cartel conduct is taken seriously. The penalties can be severe, and the risk isn’t limited to big corporations. Even early-stage startups and family-run businesses can get into trouble if they make the wrong agreement, share the wrong information, or “coordinate” prices or customers in the wrong way.

Below, we’ll break down what cartel provisions are, what conduct is risky, and what practical steps you can take to protect your business while still collaborating and competing confidently.

What Are Cartel Provisions (In Plain English)?

Cartel provisions are parts of Australian competition law (under the Competition and Consumer Act 2010 (Cth)) that prohibit certain kinds of coordination between competitors.

In practical terms, the law is trying to stop competitors from acting like a single business (instead of competing). When competitors coordinate, customers can end up paying more, getting fewer choices, or missing out on innovation.

Cartel provisions generally target agreements, arrangements or understandings between competitors that involve:

• price fixing (agreeing on prices, discounts, fees, commissions, surcharges, or minimum prices)
• market sharing (dividing up customers, territories, industries, or types of work)
• output restrictions (agreeing to limit production, supply, capacity, or how much you’ll sell)
• bid rigging (coordinating tender responses or who will “win” a bid)

You’ll sometimes hear people say “cartel behaviour” is only about secret meetings and dodgy backroom deals. In reality, cartel risk can arise from everyday interactions: industry groups, informal chats, joint ventures, reseller arrangements, and even WhatsApp groups with people in your industry.

One of the most important mindset shifts is this: cartel risk often turns on whether there’s an agreement, arrangement or understanding with a competitor about a prohibited topic (even if it’s informal). In many cases, you don’t need a signed contract for issues to arise, and regulators can look at what was said and done to infer an “understanding”.

Do Cartel Provisions Only Apply To Direct Competitors?

Cartel provisions typically apply where there is some form of competition between the parties (or potential competition). That could include:

• two businesses selling similar products to the same customer base
• two service providers pitching for similar projects
• two platforms competing for the same users
• a future competitor (for example, a supplier who could start selling direct)

Even if you don’t see someone as a competitor, the law may still view you as competing in a market in some way.

Why Cartel Provisions Matter For Small Businesses And Startups

Startups often collaborate. You might co-market, share distribution channels, partner on tenders, or join a business network where everyone talks shop.

Those are all normal activities. The risk arises when a collaboration (or even just “helpful coordination”) drifts into restricting competition.

Small businesses are also exposed because:

• Roles overlap (a founder might handle pricing, partnerships, and sales conversations personally)
• Informal communication is common (quick texts or casual chats can create evidence of an “understanding”)
• Pressure to win contracts is high (especially in tender-heavy industries like construction, IT, government procurement, and professional services)
• Industry groups can blur boundaries (competitors share information “for the good of the sector”)

It’s also worth remembering: competition issues rarely feel urgent until something goes wrong. A disgruntled ex-partner, an unhappy customer, or a competitor can all trigger scrutiny.

Good legal foundations help here, just like they do in other risk areas. For example, if you’re building a company with multiple founders and investors, having a clear Shareholders Agreement can prevent messy internal disputes later. Competition compliance is similar: it’s much easier to set the rules early than to fix issues after the fact.

The Main Types Of Cartel Conduct (With Practical Examples)

Let’s unpack the most common “buckets” of cartel provisions and how they might show up in a real business context.

1) Price Fixing

Price fixing is when competitors agree (formally or informally) on prices or pricing elements.

It’s not just “we’ll both charge $X”. It can also include agreements about:

• minimum prices
• discount levels
• credit terms
• delivery fees
• commissions
• surcharges
• how price increases will be applied

Example: Two local service businesses agree they won’t quote below a certain hourly rate because “the market needs to stop undercutting.” Even if that feels fair, it can be risky because it’s a coordinated restriction on price competition.

2) Market Sharing (Customers, Territories, Or Segments)

Market sharing is when competitors divide up who will serve which customers, regions, industries, or project types.

Example: Two agencies agree that one will focus on hospitality clients and the other will focus on eCommerce clients, and they won’t pitch for each other’s customers.

This can look “efficient”, but it may remove competitive pressure that would otherwise benefit customers.

3) Output Restrictions

Output restrictions involve competitors agreeing to limit supply, production, capacity, or sales.

Example: Two suppliers agree to cap the volume they’ll sell into a region to keep prices stable, or agree not to expand capacity for a certain product line.

For tech startups, “output” might look different, such as limiting service availability, limiting user access, or coordinating how much inventory you’ll release at launch.

4) Bid Rigging (Tender Collusion)

Bid rigging is a big risk area for industries that rely on tenders, quotes, or procurement panels.

It can include agreements about:

• who will win a tender
• who will submit a “cover bid” (a deliberately uncompetitive bid)
• not bidding at all (or withdrawing) so another business can win
• rotating winners between competitors

Example: Two contractors agree to “take turns” winning council work, so each has a steady pipeline. That can be high-risk cartel conduct.

Even a casual statement like “we won’t bid this time if you don’t bid next time” can create serious exposure.

Common “Grey Areas” That Can Accidentally Trigger Cartel Provision Risk

Many small businesses don’t set out to do the wrong thing. The problems often come from misunderstandings about what you can share or agree on.

Here are some situations to treat with extra care.

Industry Networking And Information Sharing

Industry events are valuable, but “benchmarking” can become risky when competitors start sharing:

• current or future pricing
• profit margins
• specific customers and what they’re paying
• future plans (for example, where you’ll expand next, capacity increases, or how you’ll respond to a competitor)

A good rule of thumb: if the information would help a competitor predict your next move (or coordinate theirs), pause and get advice.

Joint Ventures, Collaborations, And Teaming Up On Deals

Working together isn’t automatically cartel conduct. In fact, legitimate collaborations can be pro-competitive (for example, combining expertise to deliver a project neither party could deliver alone).

The risk is when the collaboration becomes a cover for dividing markets, fixing prices, or reducing independent competition beyond what’s reasonably necessary for the project.

In these situations, having clear written agreements matters. For example, a properly drafted Joint Venture Agreement can clarify what you’re collaborating on, how decisions are made, and what each party can and can’t do.

Distributor, Reseller, Or “We’ll Sell For You” Arrangements

Startups often scale through partners. But arrangements around resale pricing, territories, and customer allocation can create competition law concerns depending on how they’re structured.

If you’re rolling out new distribution, it’s worth also tightening up your core trading documents (like Terms of Trade) so your commercial settings are clear and consistent.

“Gentlemen’s Agreements” And Informal Understandings

One of the biggest misconceptions is that “it’s not in writing, so it doesn’t count.”

An understanding can be formed through conduct, repeated conversations, or even implied cooperation. If a regulator looks at your messages and sees a pattern of coordination, the “informal” nature won’t necessarily protect you.

This is where good internal governance helps. If you’re running a company, documents like a Company Constitution can support clearer decision-making and authority, but you also need operational guardrails (like competition compliance practices) so your team knows what not to do in the first place.

How To Reduce Risk: A Practical Compliance Checklist For Your Business

You don’t need to be paranoid to be compliant. Most businesses can reduce risk significantly with a few practical habits and clear rules.

1) Identify Where You Actually Compete

Start by mapping your “competitor universe”. Include businesses that:

• sell the same or similar products/services
• bid for the same tenders
• target the same customer segment
• operate in the same geographic area

Once you know who your competitors are, it’s easier to spot high-risk interactions.

2) Set “No-Go Topics” For Competitor Conversations

If you or your team interact with competitors (even socially or in industry groups), make it clear you shouldn’t discuss:

• prices or future pricing plans
• discount strategies
• which customers you’re targeting
• who is bidding for what
• capacity limits or supply restrictions
• plans to “stabilise the market”

If a conversation drifts into these areas, the safest approach is to clearly disengage and document that you did.

3) Be Careful With Messaging And “Quick Chats”

A casual message is still a record.

Encourage your team to treat messages like emails: clear, professional, and never suggest coordination with competitors. If you need to explore a collaboration, keep it structured and specific to the project, and avoid “big picture” coordination that affects competition.

4) Use Contracts To Keep Collaborations Tight And Legitimate

If you are collaborating, partnering, subcontracting, or forming a joint venture, document:

• the purpose of the collaboration
• the scope (what’s in, what’s out)
• how pricing will be set (independently where possible)
• how customer contact will work
• how confidential information will be handled

For example, where you’ll be sharing sensitive commercial information, an NDA can help you set rules for confidentiality and permitted use. While an NDA is not a “competition law shield”, it can support cleaner boundaries about information handling.

5) Train Your Team (Especially Sales And Partnerships)

The people most likely to create competition risk are often the people doing the growth work: founders, sales leads, partnerships teams, and procurement.

Training doesn’t need to be complicated. Even a simple one-page “competition dos and don’ts” can make a real difference.

6) Build A Habit Of Getting Advice Early

If you’re about to:

• join a consortium to bid for a tender
• enter an exclusivity arrangement
• co-launch with a competitor
• standardise pricing in a network
• share sensitive market information

It’s much easier (and cheaper) to adjust the structure upfront than to unwind it after it’s operating.

What Legal Documents Help Support Cartel Compliance (Without Overcomplicating Your Business)?

Cartel compliance is mainly about conduct, but the right documents help you run a cleaner operation and reduce the chance of messy misunderstandings.

Depending on how your business operates, these documents often come up:

• Terms and conditions / customer contract: Sets out your pricing approach, service scope, and rules for supply so you’re not “making it up” in the moment with external parties.
• Supplier or distribution agreements: Clarifies territories, exclusivity, and sales processes (so you can structure growth without accidentally drifting into anti-competitive coordination).
• Joint venture or collaboration agreement: Defines the legitimate scope of a partnership, including what information is shared and how decisions are made.
• Confidentiality agreement (NDA): Helps control how commercially sensitive information is shared and used, especially during partnership talks or due diligence.
• Employment contract and policies: Helps set expectations for your team about confidentiality, conflicts, and appropriate external communications (this becomes more important as you scale).
• Privacy policy (if you collect customer data): Not directly about cartel rules, but it’s a core compliance piece for most businesses operating online, and it supports better overall governance. A tailored Privacy Policy can help you handle personal information properly while you’re focused on growth.

The goal isn’t to drown your startup in paperwork. It’s to have the essential guardrails so your team can move fast without creating unnecessary legal risk.

Key Takeaways

• Cartel provisions prohibit certain coordination between competitors, including price fixing, market sharing, output restrictions, and bid rigging.
• Cartel risk isn’t limited to big corporations — small businesses and startups can be exposed through everyday interactions like industry networking, collaborations, and tender processes.
• “Informal” arrangements can still count as an understanding, even if nothing is signed and no one says the word “agreement”.
• You can reduce risk by setting clear no-go topics, being careful with competitor communications, and keeping collaborations tightly documented and purpose-specific.
• Strong commercial documents (like collaboration agreements, NDAs, and trading terms) support cleaner operations and reduce misunderstandings as you scale.
