Australian shoppers looking to trim their grocery bills have received a clear signal from the nation's leading consumer advocacy group. A recent price comparison by Choice has crowned Aldi as the most affordable major supermarket for a standard basket of goods, leaving rivals Coles and Woolworths trailing.
The Price Check: A Clear Winner Emerges
In December 2025, Choice investigators conducted a shop for 29 everyday grocery items. This standard basket included staples like bread, milk, cheese, mince, fresh produce, and pantry essentials. The goal was to provide a realistic snapshot of weekly shopping costs at Australia's leading supermarket chains.
The results were striking. Aldi's total came in at a wallet-friendly $112.74. This was significantly less than the two supermarket giants. Coles registered a total of $124.08 for the identical items, while Woolworths was the most expensive at $125.78.
This price check means that, for this specific basket, shopping at Aldi could save a family over $13 compared to Coles and more than $13 against Woolworths. Over a month or a year, these savings become substantial for household budgets.
What's Driving the Price Difference?
Choice's analysis points to Aldi's distinct business model as the key factor behind its lower prices. Unlike Coles and Woolworths, Aldi stocks a much higher proportion of its own exclusive brands, known as private labels. These products, which often match or exceed the quality of branded equivalents, bypass the marketing and branding costs associated with well-known names.
Furthermore, Aldi's store layout is designed for efficiency, and its product range is more curated. This streamlined approach reduces operational complexity and overheads, savings which are then passed on to customers at the checkout. The comparison highlights the tangible financial benefit of choosing supermarket-owned brands over heavily advertised national brands.
Smart Shopping Strategies for All Budgets
While Aldi emerged as the clear leader in this test, Choice emphasises that savvy shopping isn't limited to one store. The consumer champion advises that the most effective way to save is to compare unit prices – the small price per 100g or per litre label on shelves – rather than just the ticket price.
Shoppers should also consider buying seasonal fruit and vegetables, which are often cheaper, and remain flexible with brands. Opting for a supermarket's own brand of canned tomatoes, pasta, or dairy can lead to significant reductions in your total bill, whether you're at Aldi, Coles, or Woolworths.
The takeaway from Choice's grocery basket test is clear: in a time of continued cost-of-living pressures, being mindful of where you shop and what brands you choose can have a direct and positive impact on your finances. With a potential saving of over $13 on a single shop, the evidence suggests it pays to look beyond the familiar giants.
