We Priced a School Lunchbox at Coles, Woolies & Aldi

We priced 11 typical school-lunchbox items across Coles, Woolworths and Aldi — the staples that show up in the average kid's bag through a school week.

The basket, item by item

For each item we picked the cheapest reasonable match per store — store-brand where available, otherwise the cheapest national brand. Cheapest store for each row is highlighted.

Where each store wins

Aldi
Cheapest on the snacks

Muesli bars, juice poppers, sultanas, hommus, carrots. Aldi's store-brand pricing dominates packaged dry goods.

Woolworths
Surprise winner on bread & cheese

Their store-brand white bread is $2.80 vs $4.00 at Coles. Their processed cheese slices are $3.80 vs $5.40 at Coles. Both beat Aldi too.

Coles
The juice popper tax

Coles' Tetra 6-pack is $6.50. Wool's are $3.30, Aldi's are $3.00. That single item explains most of Coles' premium over the others.

How much has this lunchbox really gone up?

The basket is up -2.0% over 26 months — about -0.9% annualised, which is below the official AU food inflation rate over the same period (~4-5% per year).

The bigger story: Woolworths has held this exact basket essentially flat for the last six months. Whether that's deliberate (cost-of-living signalling) or coincidence (specials cancelling hikes), it's a real shift from the steady jumps we saw mid-2024 to mid-2025.

What this means for your weekly shop

  1. 1
    The 'Aldi is always cheapest' rule is overstated

    For a lunchbox basket, Woolworths is within $0.22 on the same items, and beats Aldi outright on bread and processed cheese.

  2. 2
    Juice poppers are the secret tax at Coles

    If you're a Coles shopper, just buy them somewhere else. That one swap saves $3-4 a week, $150-200 a year.

  3. 3
    Cherry-picking actually works

    Saving $3.17 a week across two stores adds up to ~$159 a year for one kid's lunchbox. For two kids it's nearly double.

  4. 4
    Prices have plateaued at the major supermarkets

    At least for this basket, and at least for the last 6 months. Whether that holds is the question. The next budget Wednesday will tell.

Build your own basket

We do the boring work — scraping every product price at Coles, Woolworths, Aldi and Harris Farm twice a week — so you can spend two minutes building your own list and finding the cheapest place to shop it.

Methodology: prices captured from each store's online catalogue on April 30 2026. We picked the cheapest reasonable match per item per store (store-brand if available, otherwise the cheapest comparable national brand). Coles, Woolworths and Aldi compared; Harris Farm excluded because it doesn't stock all items and is regional NSW/QLD/ACT only.
