Aldi vs Woolworths vs Coles in Brisbane: Which Supermarket Is Actually Cheaper?

Every few months, a new article appears comparing prices between Aldi, Woolworths, and Coles. The author usually identifies as a “consumer expert,” “budget advisor,” or “shopping journalist.” The headlines promise bold savings: “Switch to Aldi and save 30 percent!” or “Coles beats Aldi this week!” It all sounds impressive — until you look closer.

From personal experience, I can tell you that it is not that simple. Most of these comparisons are misleading, or at the very least, oversimplified. Grocery prices are not static, and neither are individual shopping habits.

To compare supermarket prices accurately, you must look at identical products — same brand, same size, same weight — purchased at the same time. That rarely happens. Aldi often sells its own in-house brands that are not stocked by Woolworths or Coles. Meanwhile, Woolworths and Coles carry a mix of private labels, national brands, and weekly specials that rotate constantly.

Sometimes Aldi is cheaper. Sometimes Woolworths or Coles beats it on a particular item. But none of them is consistently cheaper across every product, every week. And despite what the headlines suggest, no one is giving away groceries.

Another problem with these so-called price comparisons is the product selection. A few pantry staples, some bread, milk, and maybe a household item or two — chosen to support a particular narrative. But does that small sample reflect your actual weekly grocery basket? Does it match your personal preferences, dietary needs, or brand loyalty?

In my view, there is no ultimate “cheapest” supermarket in Brisbane. Each has its strengths. Aldi is good for staple items and simplicity. Woolworths and Coles often run specials, offer loyalty rewards, and have wider brand selections.

If you really want to save, pay attention to what you buy most often. Check weekly catalogues. Compare unit prices. Look for patterns over time — not clickbait claims from someone who may not even shop where you do.

So the next time you see another “Which supermarket is cheapest?” article, take it with a grain of salt. Trust your own shopping habits, your own budget, and your own basket. That may save you more than any headline ever will.
