Cartel conduct compliance under Australian competition law
Cartel conduct — price fixing, output restriction, market sharing, and bid rigging between competitors — is both a criminal offence and a civil penalty contravention under Part IV Division 1 of the Competition and Consumer Act 2010 (Cth). This guide walks through 10 obligations every AU business and its advisers should observe, including the ACCC's immunity and cooperation policy.
Coverage
Every corporation and individual engaged in trade or commerce in Australia. The prohibition extends to conduct outside Australia if it affects the Australian market. Directors, managers, and anyone involved in the contravention can be personally liable.
Legal basis
The cartel provisions are in Part IV Division 1 of the Competition and Consumer Act 2010 (Cth) (ss 44ZZRA-44ZZRS). The ACCC investigates and the CDPP prosecutes criminal cartel offences. The ACCC Immunity and Cooperation Policy for Cartel Conduct sets out the leniency regime.
The obligations
Never agree on prices with competitors
Agreements or understandings with competitors to fix, control, or maintain prices (or elements of price, including discounts, rebates, or credit terms) are per se prohibited.
Never agree to restrict output with competitors
Agreements to restrict or limit the supply, production, or capacity of goods or services are cartel conduct regardless of effect on the market.
Never divide markets or customers
Agreements to allocate customers, geographic territories, or product categories between competitors are per se prohibited. Non-compete undertakings between competitors are a high-risk area.
Never rig bids
Agreements between competitors about who will win, bid, withhold, or set the terms of a bid in a procurement process are cartel conduct. Cover pricing and bid suppression are captured.
Understand the joint venture exception
The joint venture exception (s 45AO) is narrow — the conduct must be for the purpose of a genuine joint venture producing goods or services and reasonably necessary for the venture. Document the analysis before relying on it.
Avoid information exchange between competitors
Exchanging commercially sensitive information with a competitor — pricing, capacity, strategy — can itself create a contravention even without an explicit agreement. Treat any information flow to a competitor as a red flag.
Train staff who deal with competitors
Staff who attend trade associations, industry forums, or supplier/customer negotiations that involve competitors need specific training. A documented compliance program is relevant to penalty.
Run a written competition compliance program
A competition law compliance program — with a policy, training, reporting channels, and board oversight — is a mitigating factor in any enforcement action and an expected standard for medium and large businesses.
Understand the immunity and cooperation policy
The ACCC grants immunity to the first eligible cartel participant to apply and fully cooperate. Immunity from criminal prosecution must be coordinated with the CDPP. Second and subsequent applicants may receive cooperation credit but not immunity.
Preserve privilege carefully in internal investigations
Where cartel conduct is suspected, internal investigations should be structured to preserve legal professional privilege. Coordinate investigation steps with external counsel before interviews or document reviews.
What happens if you do not comply
Criminal: up to 10 years imprisonment and $550,000 fine for individuals; $10 million or 3x the benefit or 10% of annual turnover for corporations. Civil: same financial penalties; court-ordered disqualification of individuals. Private damages actions by affected parties are common.
Reporting requirements
No mandatory reporting of cartel conduct. Immunity applications are made through the ACCC online form; strict first-in-time rules apply. Internal reporting under whistleblower protections (Corporations Act Part 9.4AAA) should be considered in parallel.
What firms should do today
- Map every recurring touchpoint with competitors (trade associations, standards bodies, supplier/customer panels)
- Put a meeting protocol in place for any attendance at a forum involving competitors — agenda review, minutes, walkouts documented
- Train sales, procurement, and leadership on what information cannot be exchanged with competitors
- Establish a confidential internal reporting line for suspected cartel conduct
- Review distribution arrangements, non-compete clauses, and joint venture agreements against the cartel prohibitions
- Before any immunity application, obtain specialist external competition advice within 24 hours of discovery
