Read the snapshot with its limits
These are Australian-dollar product prices checked on 5 October 2026, without coupons, subscriptions or shipping. The comparison uses the listed 30 g serving size and 33 complete serves in 1 kg. Prices and availability can change; our calculator above uses current catalogue prices.
This is a price comparison, not a claim that the formulas, certification or testing are equivalent. Our supplied label lists whey concentrate and hydrolysed whey, natural and artificial flavour, acesulfame potassium, and milk and soy. Bulk Nutrients lists whey concentrate, sunflower lecithin, flavour and sucralose for flavoured WPC; chocolate also lists cocoa. Read each flavour’s complete label.
Our products were coming soon at the check. Bulk Nutrients WPC was listed for purchase. If you need protein immediately or need delivery, that difference matters more than this product-price saving.
What is the cheapest whey protein?
The cheapest option depends on quantity, serving size, protein per serve and fulfilment costs. A headline price alone cannot establish the lowest price across Australia. Compare the same pack size and finished formula, at the same time, with every cost included.
Our live calculator shows our current 1 kg whey prices. It is a price estimate, not a claim that we are Australia’s cheapest. Pickup is free in Strathfield; delivery is paused, so this range is suitable if you can collect locally.
Bulk protein without committing to one flavour
Vanilla, chocolate and strawberry 1 kg tubs share the same whey quantity-pricing group. You can mix those flavours in one bag to reach an available tier. The product pages and your bag show the live prices; the server checks them again before payment.
The Starter Pack has a separate bundle price and does not count toward individual whey quantity tiers. Compare its current price separately: Starter Pack.
Compare cost per serving, not just the tub
Our whey labels list 24 g protein in a 30 g serving, with 33 complete servings in each 1 kg tub. Use 33 rather than rounding up to 34 when comparing complete servings. Cost per serve is the tub price divided by 33.
For another brand, use that product’s own serving count and protein figure. Compare finished flavoured products rather than assuming the ingredient’s protein percentage is the amount in every shake. Read our WPC vs WPI guide: WPC vs WPI guide.
Affordable protein with the details in view
Our whey contains whey protein concentrate and hydrolysed whey and declares milk and soy. The individual flavour pages show ingredients and preparation instructions so you can judge suitability as well as price.
The quantity saving applies to the same labelled formula and serving size. Compare ingredients, allergens and preparation details for each flavour. See Vanilla: vanilla whey · Chocolate: chocolate whey · Strawberry: strawberry whey.
Bulk retail or wholesale?
Buying several tubs for your own routine is a retail bulk order. If you are a gym, trainer or retailer buying to supply others, ask us for a wholesale quote at Wholesale enquiries.
Tell us the products, quantities and how often you expect to buy. Wholesale prices, minimum quantities and supply timing are confirmed individually; the retail calculator is not a wholesale price list.
Availability comes before payment
