The recent Coles ACCC ruling exposes a deeper crisis in retail trust — and “supplier blame” won’t fix it
When shopper trust is a euphemism for price — and both are breaking at once
The Federal Court’s finding that Coles Group misled shoppers through its “Down Down” pricing campaign is more than a regulatory setback. It is a reminder that in grocery retail, trust is not a marketing asset — it is the system itself.
The Australian Competition and Consumer Commission (ACCC) successfully argued that Coles briefly inflated prices on hundreds of items, then promoted them as discounted without those higher prices being sustained long enough to justify the “was/now” comparison. The court found that in most sampled cases, the reference price was not a genuine, durable benchmark.
That matters because supermarket pricing is built as much on perception as economics. Consumers do not track hundreds of product histories. They rely on the assumption that a “special” reflects a real reduction from a stable price — not a constructed one.
Supplier blame and a squeezed supply chain
Retailers often point to suppliers when explaining higher grocery prices. That explanation is partly true: dairy, meat, fruit, transport, and fertiliser costs have all risen sharply.
But the ACCC case is not about whether prices move — it is about how those movements are presented.
That distinction becomes sharper when looking at the supply chain itself. Primary producers are increasingly squeezed between rising input costs and strong supermarket bargaining power. In dairy, meat, and horticulture, farmers often face pressure to accept lower farmgate prices just to retain shelf access, even as their own costs rise. For some, that dynamic contributes to consolidation or exit from the sector entirely.
So while supermarkets cite supplier-driven inflation, many producers experience sustained downward pressure on returns rather than relief.
Margins, and why they don’t settle the argument
Financially, Coles and Woolworths operate on EBIT margins typically in the high 5% to low 6% range, which is relatively strong for grocery retail. By comparison, many major global supermarket retailers operate closer to around 3% EBIT margins, reflecting more intense competition in other markets.
But this comparison doesn’t resolve the issue. Even structurally modest margins can sit alongside pricing practices that distort consumer perception. The legal question is not whether margins are high or low, but whether pricing claims are accurate.
Discounters are reshaping expectations
The broader pressure comes from competitors like ALDI in Australia, and global players such as Lidl, Costco, and Walmart, which rely less on promotional narratives and more on consistent pricing. Their appeal lies in simplicity: fewer “specials” and less need for consumers to interpret whether a discount is real.
That contrast exposes a weakness in traditional supermarket models — the more complex the pricing story, the easier it is for trust to erode.
The bottom line
This case is not just about Coles. It is about whether consumers can still assume that a discount reflects a genuine, durable price change.
Supermarkets operate under real cost pressures and thin margins. Primary producers sit under even sharper pressure. But none of that resolves the central issue: pricing communication must remain truthful, not constructed for effect.
Once trust in that basic signal breaks, it is difficult to rebuild — regardless of how the economics are explained.
