About ProteinPrice
We check the big stores so you don't have to. One search, one page, the cheapest place to buy. Refreshed 12 times a day.
Protein in Australia is expensive, the cost of living keeps climbing, and prices move constantly. The same 1 kg tub of whey can swing $20 in a week as different stores cycle through their sales.
Most shoppers buy from wherever they bought last time, then quietly hand over an extra $50–60 a year they didn't need to spend.
The protein industry knows this. So shelves are full of shiny labels, hologram tubs, “hydrolysed” sticker upgrades and 700g sizes priced like 2kg bags. Marketing teams hope you don't do the maths.
Checking nine websites every time you want a tub is a chore. So nobody does it. Stores know that, and the price you pay reflects it.
ProteinPrice does that boring work for you. Twelve times a day, every product, every store. We show you the cheapest live price, the cost per 100g, and a transparent 1-to-10 value score so the marketing has nowhere to hide.
How it works
The pipeline that powers every page on this site, end-to-end.
Twelve times a day we pull fresh prices from every retailer we cover: Coles, Woolworths, Chemist Warehouse, ASN, Nutrition Warehouse, Mr Supplement, Sportys Health and more.
Same brand, same flavour, same size, same pack count. The matcher dedupes hundreds of permutations so the comparison is always apples-to-apples.
Every product gets a live 1-to-10 ProteinPrice Value Score based on its cheapest $/100g vs every other product in the same category. No paid placements, no hidden weighting, no brand favourites.
Every listing has a timestamp. You always know when the price was last verified and which store has it right now. Our methodology page lays out every rule we use to rank.
Our principles
Brands cannot pay to rank higher. Cheapest is always cheapest, full stop.
11 Australian retailers plus every brand selling direct. We compare them all on one page.
Every product carries a transparent 1-to-10 value score, calculated live from its cheapest $/100g vs the category. The formula is public.
Fresh prices 12 times a day. Sale flags fire the moment a retailer discounts.
ProteinPrice is built and run by a small independent team in Australia. No VC, no agency, no parent company. Just a handful of people who got tired of overpaying for whey and decided to fix it.
We're new. When the press start writing about us, the quotes will live here. If you're a journalist working on a story about supplement pricing or grocery price comparison in Australia, we'd love to chat.
