Every article about saving money on groceries starts with the same tips: make a list, don’t shop hungry, buy store brands. These aren’t wrong — they’re just incomplete. If you’re already doing those things and your grocery bill is still climbing, you need more specific strategies.

Australian grocery prices rose 3.8% year-on-year according to the latest ABS Consumer Price Index data. That might not sound dramatic, but on an average household grocery spend of $250-350 per week, that’s an extra $500-700 per year. The increases aren’t even — some categories like dairy, bread, and fresh produce have risen faster.

Here’s what I’ve found actually moves the needle after two years of tracking my own grocery spending.

Unit Pricing Is Your Most Powerful Tool

Since 2009, Australian supermarkets have been legally required to display unit prices — the cost per kilogram, per litre, or per unit. Most people ignore these tiny numbers on shelf labels, but they’re the single most useful piece of information in the store.

Here’s why: packaging size tricks your brain constantly. A 750g jar of peanut butter for $7 seems cheaper than a 375g jar for $4.50. But the unit price tells you the big jar costs $9.33/kg while the small jar costs $12.00/kg. In this case, the bigger jar is genuinely better value. But it doesn’t always work that way — sometimes the smaller or medium size has a better unit price, especially during sales.

Train yourself to glance at unit prices instead of sticker prices, and you’ll make better decisions on every item without any additional effort.

Buying Store Brand Isn’t Always Cheaper

This is a sacred cow of frugal shopping advice that deserves some pushback. Coles and Woolworths store brands are often good value, but not universally.

Some store brand products are genuinely identical to name brands — canned tomatoes, flour, sugar, rice, pasta, vinegar. These come from the same factories and the difference is literally just packaging. Buy store brand for these without hesitation.

But other store brand products are genuinely lower quality, which means you use more, which means the per-use cost is higher. Store brand paper towels that disintegrate on contact, cleaning products that require double the amount, or bin bags that split before they’re full. For these, you might actually spend less buying a name brand that performs as expected.

The approach that works: try the store brand once. If the quality is comparable, switch permanently. If not, stick with whatever you were using.

The Freezer Is Underused

Most Australians have a freezer that contains ice cream, frozen chips, and some mystery meat from six months ago. That’s a massive missed opportunity.

Bread freezes perfectly. A loaf of bread costs 30-50% less on markdown (those reduced-to-clear stickers). Buy two or three markdowns, freeze them, and pull out a loaf as needed. Frozen bread defrosts at room temperature in about two hours or goes straight into the toaster if you just want toast.

Cook double, freeze half. The marginal cost of doubling a recipe is minimal — a bit more ingredients, almost no extra time or energy. Freeze the second batch in portion-sized containers. This doesn’t just save money on ingredients; it saves you from ordering takeaway on nights when you’re too tired to cook. At $30-50 for a delivery meal versus $4-6 for a frozen homemade portion, the savings add up fast.

Freeze fresh produce before it goes off. Bananas going brown? Freeze them for smoothies or banana bread. Herbs wilting? Chop and freeze in ice cube trays with olive oil. Berries on sale? Freeze on a tray, then transfer to a bag. The CSIRO estimates that Australian households throw away roughly $2,500 worth of food per year. Your freezer can cut that dramatically.

Timing Your Shopping Matters

Supermarket markdown patterns are remarkably consistent. Most Coles and Woolworths stores mark down short-dated items in predictable windows:

• Bakery items: Usually late afternoon, 2-4 hours before closing
• Meat: Morning (previous day’s stock) and late afternoon
• Pre-made meals and deli items: Late afternoon
• Produce: Throughout the day as items are culled, but larger batches in the morning

Shopping 1-2 hours before closing is generally the best time for markdowns. The selection is unpredictable — you can’t plan specific meals — but if you’re flexible about what you cook, you can save 30-50% on items that are perfectly good but approaching their best-before date.

Aldi for the Basics, Specialty for the Rest

If you have an Aldi nearby, doing a split shop saves most people 15-25% on their total bill. Aldi’s model — limited range, store brands, minimal staffing — produces genuinely lower prices on staple items.

Where Aldi falls short is variety and specific brands. If you need a particular ingredient for a recipe, specific dietary products, or a wider produce selection, you’ll still need Coles or Woolworths. The strategy is to buy your staples (milk, eggs, bread, cheese, rice, pasta, tinned goods, cleaning products) at Aldi and fill the gaps elsewhere.

Track Your Spending for One Month

The most effective thing I did was spend one month recording every grocery purchase in a spreadsheet. Not to create a permanent tracking system — that’s too much work — but to establish a baseline. After one month, I could see exactly where my money was going and identify the two or three categories that were disproportionately expensive.

For me, it was pre-packaged snacks (replaced with bulk nuts and homemade items), premium cheese (reduced frequency), and buying produce I didn’t end up using (now I plan meals for 4-5 days, not 7). Those three changes alone reduced my weekly spend by about $40.

Everyone’s spending pattern is different. A month of data reveals yours. The changes that follow feel obvious in retrospect — you just need the data to see them.
