A nappy pack sticker is not a price. Two boxes that both say “$28.00” are different deals when the count drops as the size goes up. The only honest unit is cost per nappy: pack price ÷ count. Supermarket own-label / value, mainstream name brand (Pampers / Huggies-class), and overnight / training pants are different products even in the same size. Compare size class × type, then match store-to-store on that unit — not the endcap percentage or the mega-box banner alone.
These are example ranges, not surveyed 2026 prices. Entry own-label daytime nappies sit toward the bottom of a band; overnight, training pants and premium "clean" lines sit toward the top. Multibuys, Everyday Rewards / Flybuys, Chemist Warehouse specials, Subscribe & Save and warehouse bulk packs move the sticker within a band. Always divide pack price by count.
Example cost per nappy by size and type: pack price ÷ nappy count, GST usually included, before shipping and membership fees.
These examples assume everyday disposable nappies from Australian supermarkets, pharmacies, online stores and warehouse clubs, with no shipping or membership fees included. Wipes, nappy bags, cloth nappies and adult incontinence products aren't covered here.
A Coles Size 4 own-label mega-pack and a Chemist Warehouse overnight Size 3 aren't the same product, so compare each against its own row. Keep overnight nappies separate from daytime ones.
| Size class | Type | Common for | Ex. cost per nappy |
|---|---|---|---|
| Newborn / Size 1 | Supermarket own-label / value | early weeks / light use | example $0.18–0.30 |
| Newborn / Size 1 | Mainstream name brand | early weeks | example $0.25–0.40 |
| Size 2–3 | Supermarket own-label / value | everyday daytime | example $0.18–0.32 |
| Size 2–3 | Mainstream name brand (Pampers / Huggies-class) | everyday | example $0.28–0.45 |
| Size 4–5 | Own-label / club bulk | everyday / bulk | example $0.20–0.35 |
| Size 4–5 | Mainstream name brand | everyday | example $0.30–0.50 |
| Size 6+ / bigger kids | Own-label or name brand daytime | older toddlers | example $0.35–0.60 |
| Any size | Overnight / training pants | nights / potty transition | example $0.45–0.85+ |
Example ranges only, not surveyed or sourced 2026 prices. Always divide pack price by count. Overnight / training pants stay off the daytime rows. AUD. GST usually in the sticker.
Every dollar in that table is an example, not a sourced 2026 street price.
Supermarket own-label / value (Woolworths / Coles house brands, Aldi value lines, Chemist Warehouse value packs): often the lowest cost per nappy in a size class. Fit and overnight absorbency still vary by baby — test a small pack before you commit a bulk box. Club and warehouse counts (Costco Kirkland-class) usually win the $/nappy math when storage and membership already exist.
Mainstream name brand (Pampers / Huggies-class): the everyday daytime step most aisles lead with. Bulk / mega-pack sizes pull the per-nappy number toward the floor of the band; convenience packs and pharmacy singles sit toward the ceiling.
Premium / specialty (“clean” / plant-based lines): clear sticker premium for materials marketing. Fine if that is the product you want — still price it as cost per nappy in the same size class, not against an own-label mega-pack as if the gap were “savings on the same nappy”.
Overnight / training pants: more absorbent nappies for nights, and pull-up pants for potty training. They cost more per nappy than daytime nappies of the same brand, so compare them only with other overnight packs.
Always divide pack price by count. Manufacturers shrink the count as size increases, so a Size 5 box and a Size 3 box at the same shelf price are not the same value.
Multibuy / Everyday Rewards / Flybuys / Chemist Warehouse specials: these move the sticker within a band for a week or so. Compare the resulting cost per nappy before you call it a deal. A catalogue special is a short-term price, not the normal one.
Subscribe & Save / auto-delivery (Amazon and other online stores): recurring discounts move the price within a band. Compare the cost per nappy against Chemist Warehouse, Woolworths and Coles before you set up a regular order.
Warehouse / club bulk: large packs (such as Costco's Kirkland) often land at the cheap end of the daytime bands if you already have a membership and room to store them. The table doesn't include the membership fee.
Chemist Warehouse: pharmacy / baby aisle — value packs plus name-brand packs; catalogue specials move the sticker inside a band. Divide by count after any special; stay on the same size × type.
Woolworths: supermarket own-label and selected name-brand packs; Everyday Rewards / multibuy weeks move the sticker inside a band.
Coles: the other big supermarket, with its own house-brand nappies.
Big W, Target Australia, Myer, Baby Bunting and Aldi also stock nappies, from department and variety stores to specialty baby shops and discount supermarkets. Check the cost per nappy there too.
Amazon: marketplace / Subscribe & Save. Compare the unit, not the aisle banner.
Costco Australia: membership warehouse; Kirkland club bulk.
Example only, not a survey: Newborn / Size 1 own-label often lands around example $0.18–$0.30 per nappy; Newborn / Size 1 mainstream name brand around example $0.25–$0.40; Size 2–3 own-label around example $0.18–$0.32; Size 2–3 mainstream around example $0.28–$0.45; Size 4–5 own-label / club around example $0.20–$0.35; Size 4–5 mainstream around example $0.30–$0.50; Size 6+ daytime around example $0.35–$0.60; overnight / training pants around example $0.45–$0.85+. See the table. These are example ranges only, not surveyed or sourced 2026 prices. Always divide pack price by count.
Because count drops as size goes up. Two same-priced packs are rarely the same deal. Cost per nappy is pack price ÷ count.
For many babies, supermarket own-label and Aldi value nappies perform close enough to name brands that the lower cost per nappy is worth it. Fit and overnight absorbency still vary, so try a small pack before buying a bulk box.
They move the price within a band. Compare the cost per nappy at Chemist Warehouse, Woolworths, Coles and online stores before you set up a regular order. The prices on this page are examples, not current sale prices.
No, they're a different product. Overnight nappies and training pants cost more per nappy, so compare them with other overnight packs rather than with daytime Size 2–5 nappies.
