How to Spend Less on Groceries: A Practical Guide for Australians

Practical strategies for Australian shoppers to reduce their weekly grocery bill — from meal planning and price comparison to shopping specials and reducing food waste.

You can spend less on groceries by planning meals before you write your list, building that list around the weekly half-price specials, comparing prices across stores, and switching staples to home brands. Where you shop matters most: CHOICE's March 2026 basket survey put the same 20 items at $72.41 at Aldi, $98.98 at Woolworths and $100.04 at Coles.

Most Australian households spend more on groceries than they need to — not because of unavoidable price rises, but because of how most people shop. Going in without a plan, defaulting to familiar brands, and not comparing prices across stores all add up. Small habit changes can cut weekly grocery spending by 20–30% without meaningful lifestyle compromise.

Set a Weekly Budget Before You Shop

The first step to spending less is knowing how much you intend to spend. Without a target, it's easy to drift well above what's needed.

A reasonable starting point for a family of four shopping specials and generic brands is $100–$150 per week. Some households manage lower, some need more — the point is to have a number before you walk in, not after you see the receipt. Write it down or put it in your phone. A concrete target changes how you make decisions in the aisle.

Plan Meals Before You Make Your List

Meal planning is probably the single highest-impact habit for reducing grocery spend. It eliminates the two biggest forms of grocery waste: buying ingredients you don't use, and resorting to takeaway because nothing in the fridge comes together.

A basic approach: decide on five to six dinners for the week before writing your list, check what's already in the fridge and pantry, and write your list based only on what you need for those meals plus regular staples. This has a compounding effect — less waste means fewer mid-week top-up trips, and fewer mid-week trips means fewer impulse purchases.

Shop the Weekly Specials

Every major Australian supermarket runs weekly promotions. At Coles and Woolworths, half price specials reset every Wednesday. Aldi releases new Super Savers and Special Buys on Wednesdays and Saturdays.

The practical approach: check what's on sale at the start of each week and build your meal plan around it where you can. If chicken thighs are half price, plan two chicken dinners. If pasta sauce is discounted, grab three jars. This is the most direct way to lower your spend without changing what you eat.

Our weekly roundups of the Coles specials, Woolworths specials and Aldi specials cover what's worth stocking up on each week.

Promotions at Coles and Woolworths typically cycle on a rotating five to six week schedule — if you miss a deal this week, it'll usually come back within about a month.

Compare Prices Across Supermarkets

Half price at one store doesn't always mean cheapest in the market. Across a full basket, Aldi consistently comes out ahead: a March 2026 CHOICE survey found the same 20 items cost $72.41 at Aldi, against $98.98 at Woolworths and $100.04 at Coles — a gap of around $26–28 every week, and one that held up even when competitor specials were counted. Individual items at Coles or Woolworths can still beat Aldi when they're on a genuine deep discount, which is exactly why it's worth checking rather than assuming. Our full Aldi vs Coles vs Woolworths price comparison breaks down where each store wins.

Grocero lets you compare current prices across Coles, Woolworths, Aldi, and other Australian supermarkets in one place. If you have a list of items you buy every week, it's worth checking a few times to see whether your defaults are actually the cheapest options, or whether shifting some items to a different store would save you money.

Split shopping — buying staples at Aldi and the rest at Coles or Woolworths — is common among price-conscious shoppers. The inconvenience of two stops can be offset by meaningful savings on the items where Aldi is consistently cheaper.

Choose Generic Brands for Staples

For most pantry staples, supermarket-brand products are significantly cheaper than name-brand equivalents and often comparable in quality.

Things where generic brands consistently work well: flour, sugar, rice, pasta, canned tomatoes and legumes, cooking oils, frozen vegetables, cleaning products, paper goods, and many dairy items.

Things where you may genuinely prefer name brands: coffee, chocolate, specific condiments. That's fine — pick your preferences deliberately rather than defaulting to branded across the board. Switching even five or six items to generic saves around $15–25 per week depending on what they are.

Check the shelf label's unit price rather than the headline price when you compare — a bigger pack isn't automatically better value. Our guide to unit price comparison explains how to read them quickly.

Reduce Food Waste

Food waste is an invisible cost most households underestimate. Any food you buy and throw away is money wasted twice — once at the register, once in the bin.

Shop the fridge and pantry before writing your list. Don't assume you need something — check first.

Buy imperfect produce. Coles, Woolworths, and Aldi all sell cosmetically imperfect fruit and vegetables at lower prices. For anything you're cooking, there's no difference.

Freeze proteins on the day you buy them if you won't use them within two days, rather than waiting until they're almost off.

Use the whole ingredient. If a recipe calls for half a tin of coconut milk, plan a second recipe that uses the rest the same week.

Use Loyalty Programs

Both Coles (Flybuys) and Woolworths (Everyday Rewards) offer points redeemable against future grocery spending.

The key with both is activating bonus offers before each shop. The Flybuys app shows personalised bonus points promotions — "10x points on fresh produce" or "500 bonus points on a $50 spend" — that only apply if you activate them first. Most people skip this step, which means missing points they would have earned anyway. The Woolworths Everyday Rewards app has an equivalent "Boost" section with the same logic.

Avoid Impulse Buys

Supermarkets are designed to encourage purchases beyond your list. End-of-aisle displays, checkout items, and bundle deals all add to the trolley.

The most effective defence is a specific list and sticking to it. Don't browse aisles you don't need. If something catches your eye that's not on the list, note it for next week rather than adding it immediately.

Online shopping helps here — you see exactly what you're buying before checkout and there's no physical display pressure.

Shop at the Right Time for Markdowns

Coles and Woolworths markdown fresh items — meat, bakery, dairy — when they're nearing their sell-by date. This typically happens in the late afternoon and evening as staff process daily inventory.

If you have flexibility on when you shop, a mid-week evening trip often surfaces the most yellow markdown stickers. Items are fully usable on the day, or can be frozen immediately for later.

Frequently Asked Questions

How much should a family of four spend on groceries per week in Australia?

A well-planned household of four shopping a mix of specials and generic brands can typically manage on $100–$150 per week. The national average is considerably higher due to unplanned shopping and brand loyalty across the board.

Is it worth splitting shopping between Aldi and Coles or Woolworths?

For many households, yes. Aldi's basket price is consistently lower — $72.41 against $98.98 at Woolworths and $100.04 at Coles in CHOICE's March 2026 survey — so buying staples at Aldi while shopping specials at Coles or Woolworths can save meaningful money each week. Grocero makes it easy to see where prices are lowest before you decide.

What's the easiest way to reduce grocery spending quickly?

Plan your meals before writing your list, check that week's half price specials before your shop, and substitute two or three branded items for the generic equivalent. Most households see immediate savings from these three changes alone.

Does online grocery shopping save money?

It can, primarily by reducing impulse purchases and making price comparison easier. Delivery fees can offset some savings, but Click & Collect at Coles and Woolworths is often free, which removes that cost.

How do I avoid food waste?

Shop from a list built around specific meals, buy imperfect produce where available, and freeze proteins the day you buy them if you won't use them within two days. Anything in the fridge that won't get used this week should be frozen or incorporated into a meal before it turns.

Should I use a price comparison app?

Yes — especially for items you buy every week. Grocero shows current prices across Coles, Woolworths, Aldi, and other Australian supermarkets, so you can verify you're getting the best price rather than assuming.

Conclusion

Spending less on groceries doesn't require dramatic changes — it requires a plan. Build your meal plan before writing your list, shop the weekly specials, compare prices across stores, and activate loyalty offers before each visit. For a step-by-step version of this, see our guide to reducing your grocery bill in Australia.
