Estimated price per kilo across the range. Compare this figure rather than the sticker on the bag: pack sizes differ, and so does how far a kilo goes.

The detail
Where Hill's Science Diet is actually cheapest
Six retailers we track list Hill's Science Diet: Pet Circle, Petbarn, Petstock, Budget Pet Products, PETO and Habitat. We hold line-level prices at three. The Adult Chicken 12kg runs $132.00 AUD at Pet Circle against $152.00 at Petbarn, a $20.00 gap on an identical bag. Sensitive Stomach 12kg sits at $142.00 at Pet Circle, $145.00 at Budget Pet Products and $162.00 at Petbarn.
Pet Circle leads on both bags we price. On Sensitive Stomach it undercuts Budget Pet Products, $142.00 against $145.00, even though Budget Pet Products scores 88 on pricing to Pet Circle's 80. On Adult Chicken we hold only Petbarn and Pet Circle rows, so there is no Budget Pet Products figure to compare against. We hold no line prices for Petstock, PETO or Habitat on either bag. Petbarn, Petstock and PETO all price match, so carry the $132.00 Adult Chicken figure with you. Every price here is an editorial estimate from our index, not a live quote.
Bag-size economics: 12kg is the only lever
Both Hill's Science Diet bags in our index are 12kg, so the usual advice to buy bigger does not apply. There is no 15kg or 20kg step down the per-kg curve. For contrast, Black Hawk Adult Chicken & Rice comes in 20kg at $8.45 per kg and SavourLife Original Adult in 18kg at $8.06 per kg, both well under Hill's $11.58.
Within the range, the two bags are $0.84 per kg apart: $11.58 for Adult Chicken, $12.42 for Sensitive Stomach. On a roughly 15kg dog that is $2.70 against $2.90 a day, close to $73.00 a year for a one-point rating difference, 77 against 78. The brand's value score of 52 out of 100 reflects exactly this: a narrow, high-priced ladder. Per-kg and per-day figures are editorial estimates.
Autoship and member pricing on the retailers that stock it
The only Hill's price we hold under $11.00 per kg is Pet Circle autoship on the Adult Chicken 12kg: $125.00, or $10.42 per kg. That is $27.00 below Petbarn's $152.00 on the same bag, and one bag clears Pet Circle's $49.00 free-shipping threshold. Sensitive Stomach carries no autoship price here, so its Pet Circle floor stays $142.00, or $11.83 per kg.
Petbarn member pricing lands at $139.00 and $149.00 on the two bags, exactly our everyday index figure for each, and Repeat Delivery is stated at up to about 15%. Petbarn scores 86 on subscription, Pet Circle 84, Budget Pet Products 60. Budget Pet Products is flat at $145.00 on Sensitive Stomach, and a single bag clears its $59.00 free-shipping threshold. All retailer figures are editorial estimates.
Cheaper without dropping quality
Black Hawk Adult Chicken & Rice 20kg is the clean swap on the standard bag: $8.45 per kg and $2.10 a day against Hill's Adult Chicken at $11.58 and $2.70. That is roughly $219.00 a year on a 15kg dog, and the cheaper bag scores higher, 85 against 77, with Black Hawk's brand ingredient score at 76 to Hill's 57.
SavourLife Original Adult 18kg goes further at $8.06 per kg and $2.00 a day, rated 83, on a brand scoring 78 for value against Hill's 52. Prime100 is not the saving: its SK-D 8kg dry runs $14.88 per kg and $3.20 a day, above Sensitive Stomach's $12.42 and $2.90, though it rates 85. Prescription lines are a vet conversation. Prices and cost-per-day figures are editorial estimates. Not veterinary advice.
The alternatives
Cheaper alternatives to Hill's Science Diet
Scored on the same 100-point model and priced from the same index, so the comparison is like for like.
Royal Canin
Super-premium · Average
Worth it for genuine therapeutic and prescription needs, where the research is unmatched. For everyday feeding it's hard to justify: by-product- and grain-led panels at a top-tier price per kg, where much of what you're buying is the vet-clinic positioning. Compare cost per day against named-meat premium rivals before defaulting to it.

Prime100
Premium · Good
A capable single-protein option for elimination diets, and the labels are honest. But the rolls especially carry a steep price per kg for what is a deliberately simple recipe, and the range spread across formats muddies value: price the dry against the rolls per serve before you settle on one.

Black Hawk
Premium · Good
Fine on a discounted big bag if you choose a named-meat-first recipe, but don't assume the whole range is equal: the cheaper lines pad the panel with grain and rice, and a chunk of the price is reach and marketing rather than ingredients. Compare the specific formula on cost per kg against SavourLife and Ivory Coat.

Common questions
Cheapest Hill's Science Diet: FAQs
Short answers on buying this brand for less, using the same published estimates as the table above.
Prices checked
Entered and checked by hand
In our index, the best Hill's Science Diet value is Hill's Science Diet Adult Chicken 12kg at $11.58/kg, cheapest at Pet Circle. Online-only retailers like Pet Circle and Budget Pet Products are usually the price-to-beat. Always compare price per kg on the exact product.
Online-only stores like Pet Circle and Budget Pet Products often post the lowest everyday prices, while Petbarn is very competitive on member and Repeat Delivery pricing, with the bonus of stores nationwide. Compare price per kg whichever way you buy.
Buy the largest bag size you'll use before it goes stale, use subscription or autoship pricing where available, and compare price per kg rather than sticker price. The cheapest bag isn't always the cheapest feed once serving size is factored in.
If you're price-shopping, compare Royal Canin, Prime100, Black Hawk on price per kg and cost per day: you may get similar quality for less.
Not in our index. The six retailers we track that carry Hill's Science Diet are all pet specialists: Pet Circle, Petbarn, Petstock, Budget Pet Products, PETO and Habitat. The supermarket aisles we track run on house brands, Woofin' Good! at Coles, Baxter's at Woolworths, Julius at Aldi and Black & Gold at IGA. On our records Coles and Woolworths each list two national brands alongside the house label, IGA lists one, and Aldi lists none. Hill's scores 77 out of 100 on availability, which is strong for a specialist brand rather than a grocery one.
On the figures we hold it depends on the bag. Adult Chicken 12kg falls from $132.00 to $125.00 on autoship, a $7.00 saving, or $11.00 down to $10.42 per kg, and that $10.42 is the lowest Hill's number anywhere in our index. Sensitive Stomach carries no autoship price with us, so committing buys nothing on that bag beyond the $142.00 everyday price. Petbarn, Petstock and PETO all offer price matching if you would rather not lock in. Prices are editorial estimates, so confirm before buying.
The gap is $149.00 against $139.00 on the same 12kg pack, $12.42 versus $11.58 per kg, and $2.90 against $2.70 a day for a roughly 15kg dog. On our scoring the two are almost level, 78 and 77 out of 100, and both list chicken first at 22% protein, with fat at 15% versus 14%. If your dog has a specific digestive need, that is a conversation with your vet rather than a value calculation. Not veterinary advice.
