The cost of groceries in tuckara.com/post/best-budget-home-essentials-new-homes-australia" title="Best Budget Kitchen Gadgets Under Australia">Australia has become a genuine financial pressure for most households. With Cleaning Products in Australia 2026 — Aldi vs Kmart vs Supermarket Brands Tested">supermarket pricing under more scrutiny than ever in 2026, the question of where to shop has real money attached to it.
We compared a standard 30-item weekly shop across Aldi, Woolworths and Coles. Here's what we found — and what it means for how you should be spending your grocery budget.
The Short Answer
Aldi is cheaper. Significantly cheaper — typically 20–35% less than Woolworths and Coles on comparable items. For a family spending $200 a week on groceries, switching primary shopping to Aldi can save $40–$70 per week, or $2,000–$3,600 per year.
But it's more complicated than that. Here's the full picture.
Where Aldi Wins Clearly
Pantry Staples
Pasta, rice, flour, oil, tinned tomatoes, legumes, sugar, coffee — on these categories Aldi is consistently cheaper and the quality is genuinely comparable or better. There is almost no reason to buy these items at Woolworths or Coles if an Aldi is accessible to you.
Dairy
Milk, butter, cheese and yoghurt are all significantly cheaper at Aldi. The quality is solid. Aldi milk is priced fairly, unlike the loss-leader pricing at the majors that has historically squeezed dairy farmers.
Bread
Aldi's baked goods — particularly their sourdough and multigrain loaves — are genuinely good and considerably cheaper than comparable loaves at the big two.
Fresh Produce — Sometimes
Aldi produce is hit or miss depending on the week and the item. When it's good, it's excellent value. When it's not, you'll notice. Fruit and vegetables are worth inspecting in store rather than assuming quality.
Where Woolworths and Coles Have an Edge
Range and Availability
Woolworths and Coles carry significantly more products. If you have dietary requirements, specific brand preferences, or cook cuisines that need specialty ingredients, the majors will serve you better. Aldi's range, while well-curated, is intentionally limited.
Online Shopping
Neither Woolworths nor Coles is particularly cheap, but they both offer online shopping with delivery and click-and-collect. Aldi has no online grocery shopping in Australia. If convenience matters, the majors win here.
Loyalty Programs
Everyday Rewards (Woolworths) and Flybuys (Coles) return real value for consistent shoppers — particularly if you stack with cashback apps like Shopback or Cashrewards. Aldi has no loyalty program.
Meat Quality
Woolworths and Coles have better and more consistent meat selections, more variety of cuts, and more reliable access to specific proteins. Aldi meat is fine but the range is limited.
The Smart Approach: Split Shopping
The household that saves the most on groceries is rarely the one that shops exclusively at one store. The practical approach used by most budget-conscious Australians is:
Aldi first — pantry staples, dairy, bread, eggs, any produce that looks good, any Special Buys worth having.
Woolworths or Coles second — whatever Aldi doesn't stock: specific proteins, specialty items, branded products you actually care about, fresh items where you want more variety.
This approach typically delivers savings of 15–25% compared to shopping exclusively at the majors, without the inconvenience of sourcing everything from Aldi alone.
The Cashback Layer
If you shop at Woolworths, Shopback and Cashrewards both offer cashback on Woolworths purchases — typically 2–5% depending on current promotions. Stack this with Everyday Rewards points and you recover some of the price difference between Woolworths and Aldi on the items you need to buy there anyway.
Is Aldi actually cheaper than Woolworths in Australia?
Yes — Aldi is typically 20–35% cheaper than Woolworths on comparable grocery items. The biggest savings are on pantry staples, dairy, and bread. Fresh produce varies by week and item.
How much can you save shopping at Aldi instead of Coles or Woolworths?
A household spending $200 per week on groceries can typically save $40–$70 per week by switching primary shopping to Aldi — that's $2,000–$3,600 per year. Savings are highest on pantry staples and dairy, lower on fresh produce and specialty items.
What does Aldi not have that Woolworths and Coles do?
Aldi has a limited range compared to the majors — no online shopping, no loyalty program, fewer specialty and international ingredients, a smaller meat selection, and less variety overall. Aldi works best for staple groceries, with Woolworths or Coles filling the gaps.
