Woolworths, by a little. In CHOICE's June 2026 price survey of 104 supermarkets in 27 locations, the same 17 groceries cost $74.47 at Woolworths and $76.79 at Coles, so Woolworths was $2.32 (about 3 per cent) cheaper. With specials the gap was $2.79. Aldi beat both at $68.89.

Why the Gap Is So Small
Three per cent on one basket doesn't make Woolworths cheaper for everything. CHOICE found most items were identical or very similar in price at the two chains, and on any single product either one can be cheaper that week.
Both supermarkets use sophisticated pricing strategies. They rotate half-price specials on a weekly cycle, typically on Wednesdays. They price-match each other on hundreds of staple items. They use loss leaders to get you through the door. And they both know that once you're inside, you'll probably spend more than you planned.
The difference comes down to what you buy, when you buy it, and which own-brand products you prefer. Let's break it down.
The basket totals come from CHOICE's June 2026 price survey, linked above. The category notes below are general patterns, not a price survey of our own. Prices vary by location and change weekly, so treat this as a general guide rather than a guarantee.
Where Woolworths Wins
Fresh Produce
Woolworths has consistently edged out Coles on fresh fruit and vegetables in 2026. Their supply chain investments over the past few years are paying off. You'll often find that basics like bananas, tomatoes, and leafy greens are a few cents cheaper per kilo at Woolworths, and the quality tends to be marginally better too.
Their “Odd Bunch” range also deserves a mention. If you don't mind cosmetically imperfect fruit and veg, it usually costs less than the regular shelf price. Coles has a similar offering, but Woolworths tends to stock it more consistently.
The Macro Brand
Woolworths' Macro Organic and Free Range range has become genuinely impressive. If you're buying organic, free-range, or health-conscious products, Macro often undercuts dedicated health food brands by a significant margin. The quality is solid too. Their Macro organic peanut butter, for instance, is about half the price of comparable brands and tastes just as good.
Online Shopping Experience
Woolworths' online platform and app are a step ahead in 2026. Delivery slots are more available, the interface is cleaner, and their “Scan & Go” in-store feature genuinely saves time. If you do a significant portion of your shopping online, Woolworths makes the experience smoother.
Their Everyday Rewards programme also integrates nicely with online orders, automatically applying any available Boost offers without you having to remember to activate them.
Where Coles Wins
Pantry Staples
When it comes to the dry goods that fill your cupboard, Coles frequently comes out ahead. Pasta, rice, canned goods, cooking oils, flour, sugar: the basics that make up the backbone of most Australian kitchens tend to be a touch cheaper at Coles. It's not a dramatic difference on any single item, but it adds up over a full trolley.
Coles also runs aggressive multi-buy deals on pantry items. Their “2 for” specials on things like pasta sauce, tinned tomatoes, and cereal are frequently better value than what Woolworths offers in the same week.
Coles Brand Quality
Both supermarkets have invested heavily in their own-brand ranges, but Coles has quietly pulled ahead in several categories. Their “Coles Finest” premium line rivals name brands in quality, and their standard Coles Brand products have improved noticeably over the past year. The Coles Brand Greek yoghurt, sourdough bread, and frozen vegetables are all excellent for the price.
Where Woolworths has Macro for organic shoppers, Coles has “I'm Free From” for allergy-friendly products, and “Nature's Kitchen” for plant-based options. Both are competitively priced and save you from paying a premium at specialty stores.
Flybuys Rewards
Let's be real: loyalty programmes at Australian supermarkets aren't going to make you rich. But if you're going to shop somewhere regularly, Coles' Flybuys programme currently offers better value than Woolworths' Everyday Rewards. The ability to convert Flybuys points to Velocity Frequent Flyer points, use them at Kmart and Target, or get fuel discounts at Shell gives you more flexibility.
Coles also runs “10x points” promotions more frequently, and their personalised offers through the app tend to be more generous. If you're disciplined about activating offers before you shop, you can accumulate points faster at Coles.
What About Aldi?
You can't have a conversation about supermarket prices in Australia without mentioning Aldi. And for good reason: on a like-for-like basis, Aldi is almost always cheaper than both Woolworths and Coles. In CHOICE's June 2026 survey its basket was $5.58 (about 7 per cent) cheaper than Woolworths and $7.90 (about 10 per cent) cheaper than Coles.
The trade-off is range. Aldi stocks around 1,500 products compared to over 20,000 at Woolworths or Coles. You won't find your favourite specific brand of anything. Their stores are no-frills. And if you need something niche, you're making a second trip anyway.
The smart play for many Australian families is to do a base shop at Aldi for pantry staples, dairy, and their excellent bread range, then top up at Woolworths or Coles for specific brands and fresh items. It takes more time, but the savings are real.
Aldi's “Special Buys” on Wednesdays and Saturdays are also worth checking. They're famously unpredictable (ski gear next to kitchen appliances next to camping equipment), but when they have something you need, the price is usually unbeatable.
The Real Way to Save
Here's the pattern that keeps showing up: the supermarket you choose matters less than how you shop. The families saving the most money aren't the ones who picked the “right” supermarket. They're the ones who actually know where their money goes.
Most of us massively underestimate how much we spend on groceries. The average Australian household spends over $250 per week, but when you ask people to guess, they typically say $150 to $180. That gap between perception and reality is where the real savings hide.
This is exactly why we built Alydo. Not to tell you which supermarket is cheaper (the answer changes every week), but to show you exactly where your grocery money is going. When you can see that you're spending $45 a week on snacks or $30 on drinks you barely touch, that's worth more than saving 50 cents on a tin of tomatoes.
Track your receipts for a month. The patterns that emerge will surprise you. They always do.
How to Compare Prices Across Stores
If you want to get serious about finding the cheapest option, here are practical strategies that actually work in Australia.
Compare Unit Prices, Not Shelf Prices
Both Woolworths and Coles are legally required to display unit prices (price per 100g, per litre, per unit) on shelf labels. This is your best friend. A larger pack might look more expensive but actually be cheaper per unit. Conversely, some “value” sizes are barely cheaper than the regular option. Always check the small print on the label.
Know the Specials Cycle
Both supermarkets rotate their half-price specials on a roughly predictable cycle. Most popular branded products go on half price every 4 to 6 weeks. If you can stock up on non-perishables when they're half price, you effectively halve your spending on those items. Keep a rough mental note of when things go on sale and buy enough to last until the next cycle. To see this week's specials, Alydo lists every special in the Coles catalogue and the Woolworths catalogue for Melbourne, biggest % off first, with no account needed.
Use the Apps
Both the Woolworths and Coles apps show current specials and let you build shopping lists. Apps like WiseList compare prices across both stores in real time. Spending five minutes checking prices before you shop can save you $10 to $20 per trip. Over a year, that adds up to over $500.
Track What You Actually Spend
This is the step most people skip, and it's the most valuable one. Scanning your receipts into an app like Alydo takes one photo, and over time it builds a complete picture of your spending habits. You'll see which categories eat up your budget, which items have crept up in price, and where you're spending more than you realised.
Don't Overlook Store Brands
Both Woolworths and Coles own-brand products are typically 30 to 50 per cent cheaper than name brands. In blind taste tests, most people can't tell the difference for staples like milk, cheese, bread, canned vegetables, and cleaning products. Switching even half your shop to store brands can save a typical family $50 to $80 per week.
Frequently Asked Questions
Is Woolworths or Coles cheaper for a full weekly shop?
It depends on what you buy. For a typical mixed basket, the difference is usually less than 5 per cent either way. Woolworths tends to win on fresh produce and organic products, while Coles often edges ahead on pantry staples and multi-buy deals. The biggest factor isn't which store you choose; it's whether you buy on special, use own-brand products, and stick to a list.
Is Aldi really that much cheaper than Woolworths and Coles?
Yes, though by less than its reputation suggests. In CHOICE's June 2026 survey Aldi's basket was about 7 per cent cheaper than Woolworths and 10 per cent cheaper than Coles. The main trade-off is a much smaller product range (around 1,500 items versus 20,000+) and no name brands. Many families find the best approach is to do a base shop at Aldi and top up at Woolworths or Coles for specific items.
When do Woolworths and Coles change their specials?
Both supermarkets update their specials every Wednesday. New half-price deals, multi-buy offers, and promotional prices all kick in on Wednesday morning. The previous week's specials end on Tuesday night. Planning your shop around the Wednesday changeover gives you the widest selection of current deals. Just be aware that not every special is the saving it appears to be: the Federal Court found in May 2026 that some “Down Down” discounts misled shoppers.
How can I track whether my grocery spending is going up?
The simplest approach is to scan your receipts into a tracking app like Alydo, which automatically categorises your purchases and shows spending trends over time. Alternatively, save your receipts and tally them monthly, then compare the total with what you guessed you spend.
