The school tuckara.com/post/aldi-lunchbox-ideas-aussie-kids-under-3" title="ALDI Lunchbox Ideas for Brands (Australia Edition)">Aussie Kids Under Australia 2026">lunchbox is one of those quiet ongoing costs that doesn't feel dramatic until you add it up. If you're spending $4–$6 per child per day on lunchbox food — a muesli bar here, a pouch of yoghurt there, a small tub of dip, some packaged crackers — you're easily spending $20–$30 per child per week on lunches alone. For two kids, that's potentially $60 a week, or over $2,400 a school year, just on lunchboxes.

This guide is a full week of lunchbox plans for school-aged children, designed to be made from Woolworths and Coles staples, and to cost under $20 total for the entire week per child. That works out to $4 per day — which, once you see what goes in, is genuinely achievable without any sacrifice in quality, nutrition, or the likelihood that the food will actually be eaten.

We've also included practical tips on what works, what gets left in the box, and how to make the whole operation faster on school mornings when time is tight.

The Under-$20 Weekly Lunchbox Shopping List

Here's what you'll need to buy to cover all five days. Most of these are items you'll likely already have partially stocked, and many carry over to multiple lunches.

Staples (buy once, use across the week):

  • 1 loaf sandwich bread (~$2.50 for a 700g loaf)
  • 1 block tasty cheese (~$5 for 500g — you'll only use about half)
  • 1 pack leg ham from the deli, 150g (~$3.50)
  • 1 jar peanut butter or almond butter (~$3 — lasts several weeks)
  • 1 jar strawberry or raspberry jam (~$2.50 — lasts weeks)
  • 1 tub Greek or fruit yoghurt (~$3 for 500g tub)

    • Produce:

  • 1 bunch of bananas (~$2 — use 1 per day)
  • 1 bag of apples (~$3 for a bag of 6–8)
  • 1 bag of baby carrots or 3 whole carrots (~$1.50)
  • 1 punnet strawberries or grapes if in season (~$3)
  • 1 cucumber (~$1.50)

    • Extras:

  • 1 box of crackers (Salada, Vitawheat, or home brand) (~$2)
  • 1 bag of popcorn kernels (~$2 — makes a week of popcorn for cents per serve)

    • Approximate weekly total: $18–$22 (varying by what you already have at home)

    The key principle is buying whole, unpackaged ingredients rather than pre-portioned snacks. A 500g block of tasty cheese costs $5 and provides cheese for dozens of servings. A pack of individually wrapped cheese portions costs $5 and provides 12. The packaging is what you're paying for with pre-portioned snacks — not the food.

    Monday: Classic Ham and Cheese with Fruit and Veg

    Estimated cost: ~$3.20

    Monday calls for reliability. This is the lunchbox that goes in smoothly, gets eaten without complaint, and sets a positive tone for the week. Nothing fancy — just genuinely good food made from quality ingredients.

    What's in the box:

  • 2 slices of bread, toasted or fresh, with leg ham and tasty cheese (~$1.20)
  • 5–6 baby carrot sticks (~$0.20)
  • 3–4 slices of cucumber (~$0.15)
  • Small tub of yoghurt (portioned from the 500g tub into a reusable container) (~$0.60)
  • 1 banana (~$0.30)

    • Notes: Toast the bread the night before and let it cool completely before assembling — toasted sandwiches survive the lunchbox environment much better than fresh bread, which can go soggy by morning tea. If using fresh bread, an ultra-thin layer of butter on both sides of the bread (not a smear of margarine, actual butter) acts as a moisture barrier against the ham and cheese.

    Portion the yoghurt into a small reusable container rather than buying individual yoghurt pouches. The 500g tub contains around 5–6 serves at 80g each, which is exactly a week of yoghurt for one child at a cost of about 60 cents per serve rather than $1.20–$1.50 for individual pouches.

    Tuesday: Peanut Butter and Banana Roll-Up with Crackers

    Estimated cost: ~$2.80

    Roll-ups are a legitimate strategy for children who have started finding regular sandwiches boring. A wrap or flat bread is used instead of sliced bread, and the filling is rolled tight and cut into pinwheel pieces — which somehow makes exactly the same ingredients seem more interesting.

    What's in the box:

  • 1 medium flour tortilla or Mountain Bread wrap, spread with peanut butter and sliced banana, rolled tight and cut into 4 rounds (~$0.80)
  • 8–10 crackers (Salada or home brand) (~$0.30)
  • Small piece of tasty cheese, cubed (~$0.50)
  • 1 apple, cut into slices (a squeeze of lemon juice on the cut apple prevents browning) (~$0.40)
  • Small handful of grapes or strawberries (~$0.40)

    • Notes: The peanut butter and banana combination is classic for a reason — it's genuinely delicious, provides sustained energy from the protein and natural sugar, and requires almost no preparation. If the school has a nut-free policy, sunflower seed butter (available at Woolworths) is an excellent substitute.

    Crackers and cheese in a lunchbox are universally popular with school-aged children and take about 45 seconds to prepare. Keep a small zip-lock bag of pre-cut cheese cubes in the fridge and lunchbox prep becomes even faster.

    Wednesday: Egg Salad Sandwich with Homemade Popcorn

    Estimated cost: ~$2.50

    Midweek calls for a protein hit. Eggs are one of the cheapest high-quality proteins available in Australia — a 12-pack from Woolworths is around $4.50–$5, making each egg roughly 40 cents. Hard-boiled eggs can be cooked on Sunday night, refrigerated, and used across the week. Egg salad takes 3 minutes to make.

    What's in the box:

  • 2 slices bread with egg salad filling (~$0.80)
    • (2 hard-boiled eggs, 1 tbsp mayo, squeeze of lemon, salt, pepper — mash together)
  • Small bag of homemade popcorn (~$0.10)
  • Baby carrots (~$0.20)
  • 1 banana (~$0.30)
  • Yoghurt portion (~$0.60)

    • Notes: Homemade popcorn is extraordinarily cost-effective. A 500g bag of popcorn kernels from Woolworths costs around $2 and makes approximately 20–25 serves of popcorn. Per lunchbox serve, you're spending about 10 cents. Pop a batch on Sunday, season lightly with salt, and store in a zip-lock bag or container. Compare that to a $1.50 packaged snack bag of popcorn.

    Hard-boil a batch of 5–6 eggs on Sunday (10 minutes in boiling water, then into an ice bath to stop cooking) and keep them unpeeled in the fridge. They last all week and are the easiest lunchbox protein there is.

    Thursday: Mini Cheese and Tomato Pita Pizzas

    Estimated cost: ~$3.50

    Thursday lunches can drag if they feel repetitive. Mini pita pizzas assembled the night before — toasted briefly and packed cold — give the week's lunchbox rotation something completely different while using cheap, familiar ingredients. Most children are enthusiastic about anything that resembles pizza.

    What's in the box:

  • 2 mini pita breads (or 1 regular pita halved) with pizza sauce, grated tasty cheese, and a small amount of diced ham (~$1.50)
    • (Toast at 180°C for 8 minutes the night before, cool completely before packing)
  • 1 apple (~$0.40)
  • Baby carrots and cucumber sticks (~$0.35)
  • Small portion of yoghurt (~$0.60)

    • Notes: Mini pita breads are available at Woolworths in packs of 8–10 for around $2.50. Each child gets 2 mini pizzas which is a satisfying lunch. The pizzas should be cold by lunchtime (they're packed from the fridge in the morning), which is absolutely fine — think of them like pizza by the slice, which is excellent cold.

    Use tomato paste thinned with a little water as the pizza sauce — it costs cents per pizza and tastes much better than tomato ketchup as a base. A small handful of grated cheese and a few pieces of ham is all it needs.

    Friday: Ham and Cream Cheese Crackers with Strawberries

    Estimated cost: ~$3.20

    Friday lunchboxes call for something that feels a little bit special to close out the week. This one leans into the "snack plate" format that children consistently love — multiple small items rather than one main sandwich. It takes slightly longer to assemble but involves no cooking and packs well.

    What's in the box:

  • 10–12 crackers (Salada, Jatz, or home brand) (~$0.40)
  • 2 tbsp cream cheese in a small container for dipping or spreading (~$0.50)
  • 3–4 slices leg ham, rolled up (~$0.80)
  • Punnet of fresh strawberries or a small bunch of grapes (~$1.00)
  • 1 small piece of chocolate or a few dried apricots as a Friday treat (~$0.30)

    • Notes: The "snack plate" format — sometimes called a bento or lunchable style — is one of the most consistently eaten lunchbox formats for school-aged kids. The variety of small items makes lunch feel more interesting than a sandwich, and there's something psychologically pleasing about a box divided into separate items rather than one big thing.

    A small Friday treat doesn't need to be expensive. Three or four squares of chocolate broken from a family block costs about 15 cents and is a genuinely appreciated end to the week.

    Universal Lunchbox Tips for Australian Families

    Make it the night before, always. School morning lunches made under time pressure lead to shortcuts, forgotten items, and stress. The ten minutes you spend on Thursday night making Friday's lunchbox is the best ten minutes you'll spend all week.

    Use reusable containers exclusively. The cost of zip-lock bags, gladwrap, and individual snack pouches adds up significantly over a school year. A set of 3–4 small reusable containers and a good lunchbox costs $15–$20 and lasts years.

    Keep a "lunchbox basket" in the fridge. Pre-cut vegetables (carrots, cucumber, capsicum), hard-boiled eggs, and portioned yoghurt all stay in a designated spot in the fridge so assembling lunch requires almost no decision-making. Grab from the basket, assemble, done.

    Don't add an ice brick — add frozen water. A small drink bottle filled with water and frozen overnight keeps the lunchbox cold all morning, provides a cold drink by lunchtime, and costs nothing. Dedicated ice bricks work well too but require no spending.

    Rotate ingredients, not concepts. The lunchbox formula (protein + carb + vegetables + fruit + small snack) stays constant — only the specific ingredients change. This keeps prep predictable while preventing boredom.
