Cheapest Supermarkets in Australia 2026: Where to Shop to Save the Most
Looking for the cheapest supermarkets in Australia in 2026? This guide compares Aldi, Coles, Woolworths, IGA, Drakes and Costco across Sydney, Melbourne, Brisbane, Adelaide, Perth and Canberra — and shows how ROOPON members stack extra partner discounts on top.
The short answer
Across every Australian capital city in 2026, Aldi remains the cheapest supermarket for a weekly shop built around private-label staples. For bulk buys and family households, a monthly Costco run paired with a weekly Aldi shop is typically the lowest total grocery spend.
Coles and Woolworths remain competitive on weekly catalogue specials — especially meat, frozen, and household items — but their everyday pricing on pantry basics is consistently higher than Aldi.
Prices and ranges change by state. Use the city-by-city breakdown below to plan your grocery strategy.

Six Ways to Cut Your Weekly Grocery Bill in 2026
Shop your list, not the aisle — the majors make most margin on impulse adds.
Use the Coles and Woolworths weekly catalogues to time non-perishables.
Buy private-label staples (flour, oats, pasta, UHT milk) at Aldi.
Combine a weekly Aldi shop with a monthly Costco pantry run for families of 4+.
Check unit pricing (per 100g / per litre) — bigger packs are not always cheaper.
