ACCC sues Sunny Queen and 11 egg suppliers over alleged cartel conduct

When parties stop competing, consumers ultimately miss out

So the ACCC is saying these egg companies worked together to keep prices up. How do they prove that without a smoking gun email saying "let's fix prices"?

Mimi

That's exactly why concerted practice matters. The law doesn't require a formal agreement. The ACCC is alleging coordination on specific actions—buying that Queensland property together, restricting what Kinross could sell, managing production volumes. Those actions themselves are the evidence.

Luke

But we should be careful here. The ACCC has alleged this. Sunny Queen denies it. We don't know yet what evidence the ACCC actually has or how a court will assess it. This is the opening of a case, not a finding of guilt.

Mark

Fair point. So what makes this case significant beyond just one industry?

Mimi

It's the first concerted practice case since 2017. That's nine years of the law existing without being tested in court. If the ACCC wins, it sets a template for how coordination without formal agreements gets prosecuted. If they lose, it narrows what the law can actually reach.

Luke

And we should note that the ACCC's own framing—that the industry is highly concentrated with high barriers to entry—is part of their case. They're saying the structure of the market made this kind of coordination possible and harmful.

Mark

Does Sunny Queen's denial change anything?

Mimi

Not legally. Every defendant denies charges. What matters is what evidence emerges in court. But Sunny Queen's statement that it was cooperating with the investigation is worth noting—it suggests the ACCC had access to information, documents, or testimony from inside the company.

Luke

Though we don't know how much cooperation actually happened or what it revealed. That's still to come.

  • Sunny Queen, controlling a third of Australia's wholesale egg market, and eleven other producers allegedly moved in quiet lockstep for years — managing supply, culling birds, and carving up distribution to suppress the competition that consumers depend on.
  • The alleged conduct extended to purchasing a Queensland property solely to keep rivals out, and to blocking competitor Kinross Farm from supplying eggs to Coles, Woolworths, Aldi, and Costco — shutting a smaller player out of the shelves that matter most.
  • With Australians consuming more than 250 eggs per person each year, the ACCC argues this coordination translated into real harm: higher prices and narrower choices for millions of families buying what is, for many, a daily staple.
  • Sunny Queen has denied all allegations, insisting its arrangements concerned legitimate shareholder and supplier agreements, and says it will continue operating normally as the case moves through the courts.
  • This is the ACCC's first concerted practice prosecution since the prohibition was legislated in 2017 — a legal frontier where coordination without formal agreement must now be proven, and where the verdict will shape how regulators pursue the subtlest forms of collusion.

When the businesses that feed a nation quietly agree to stop competing with one another, the cost is borne by ordinary households who never knew a choice was being made for them. Australia's competition regulator has brought the country's largest egg supplier and eleven fellow producers before the federal courts, alleging that since 2020 they coordinated production, distribution, and market access in ways that kept prices artificially elevated and rivals artificially constrained. The case is the first of its kind under a prohibition introduced nearly a decade ago, and its outcome may define how quietly arranged cooperation — without a signed agreement in sight — is understood and punished under Australian law.

Australia's competition regulator has taken the country's largest egg supplier and eleven other producers to federal court, alleging years of coordinated conduct that quietly reshaped a market most Australians take for granted. The Australian Competition and Consumer Commission filed civil proceedings against Sunny Queen — which holds roughly one-third of the wholesale egg market — along with Doug Hall Poultry, McLean Farms, Kinross Farm, Ellerslie Free Range Farms, Yallamundi Farms, and six others. The ACCC alleges that since at least October 2020, these businesses coordinated production volumes, distribution decisions, expansion timing, and culling practices, all in service of managing what they characterised as oversupply while keeping genuine competition at bay.

The alleged behaviour extended well beyond informal market alignment. The ACCC claims Sunny Queen, Hall Poultry, and McLean Farms jointly purchased a Pittsworth, Queensland property specifically to prevent rival suppliers from acquiring it. The regulator also alleges Sunny Queen used its dominant position to limit how many eggs Kinross Farm could sell and to block Kinross from supplying major retailers including Coles, Woolworths, Aldi, Metcash, and Costco. Given that Australians consume more than 250 eggs per person annually, the ACCC chair Gina Cass-Gottlieb argued that this kind of coordination carries a direct cost to households — suppressing the lower prices and broader choices that functioning competition would otherwise deliver.

Sunny Queen denied the allegations, saying it had cooperated fully with the investigation and that the case concerned the terms of its agreements with shareholders and key suppliers. The company said it would continue normal operations while the matter is before the courts. The other named producers had not publicly responded at the time of filing.

The case carries weight beyond the egg industry. It is the first time the ACCC has pursued proceedings under the concerted practice prohibition introduced in 2017 — a provision designed to capture coordination that falls short of a formal written agreement. How Australian courts interpret that standard in a concentrated, high-barrier industry will set a precedent that reaches far beyond any single carton of eggs.

Australia's competition regulator has taken the country's largest egg supplier and eleven other producers to federal court, alleging they worked together to control the market in ways that likely harmed consumers for years. The Australian Competition and Consumer Commission filed civil proceedings on Tuesday against Sunny Queen—which controls roughly one-third of the wholesale egg market—along with Doug Hall Poultry, McLean Farms, Kinross Farm, Ellerslie Free Range Farms, Yallamundi Farms, and six other companies. The ACCC alleges that since at least October 2020, these businesses coordinated decisions about how much to produce, where to distribute eggs, when to expand operations, and how many birds to cull, all in ways designed to manage what they saw as oversupply and to keep competition from functioning normally.

The alleged coordination went beyond boardroom conversations. According to the regulator, Sunny Queen, Hall Poultry, and McLean Farms jointly purchased a property in Pittsworth, Queensland, specifically to prevent rival suppliers from buying it—a move the ACCC says substantially reduced competition. The regulator also alleges that Sunny Queen used its market dominance to restrict how many eggs its competitor Kinross Farm could sell and blocked Kinross from supplying eggs to major retailers including Coles, Woolworths, Aldi, Metcash, and Costco. These are not small players in the Australian food system. Sunny Queen alone operates warehouse and distribution facilities across Queensland, New South Wales, Victoria, South Australia, and Western Australia. Australians consume more than 250 eggs per person annually, making eggs a genuine household staple whose price and availability matter to millions of families.

ACCC chair Gina Cass-Gottlieb framed the case in terms of what consumers lose when competitors stop competing. When businesses work together instead of against each other, she explained, shoppers miss out on the lower prices and wider choices that real competition delivers. The regulator's concern is that the alleged coordination created an artificial scarcity—managed oversupply—that kept prices higher than they would have been in a genuinely competitive market. The egg industry itself is structurally vulnerable to this kind of conduct. It is highly concentrated, dominated by a small number of large suppliers, and has significant barriers to entry and expansion, meaning new competitors cannot easily challenge the incumbents.

Sunny Queen denied all allegations in a statement, saying it had cooperated fully with the ACCC's investigation and characterizing the case as relating to the terms of its agreements with shareholders and main egg suppliers in Queensland and Victoria. The company said it would continue operating normally while the matter proceeds through the courts. Doug Hall Poultry, McLean Farms, Kinross Farm, Yallamundi Farms, and Ellerslie Farmers were contacted for comment but have not yet responded publicly.

This case marks a significant moment in Australian competition law. It is the first time the ACCC has brought proceedings involving concerted practice allegations since that prohibition was introduced in 2017. A concerted practice, as the regulator defines it, involves cooperation between businesses that goes beyond each company simply responding independently to market conditions. It can include coordination without any formal written agreement—which is precisely what makes it harder to detect and prosecute. The ACCC's decision to pursue this case suggests the regulator believes it has evidence of sustained, deliberate coordination among competitors, and it will test how Australian courts interpret and enforce the concerted practice prohibition in a real-world industry.

When you have good functioning competition then you have more choice, you also have price competition so lower prices. Our concern is that when parties are not competing and they start working together and consumers can ultimately miss out.
