Costco arrived in Australia in 2009 and has grown to 15 warehouses doing an estimated $5 billion in annual sales — more profit than Aldi Australia last financial year. The concept is simple: pay a flat annual fee and shop at wholesale prices. Whether that $65 is money well spent or a fee that quietly drains your wallet depends entirely on where you live, how big your household is, and whether you know which categories to stick to. This guide gives you the honest version.
The questions Australians ask most — before handing over their $65. Answered plainly, without the marketing gloss.
There are two tiers. The Gold Star membership costs $65 per year and covers the primary cardholder plus one additional household member at no extra charge. The Executive membership costs $130 per year and adds a 2% annual reward on eligible purchases (capped at $1,000 per year), which pays for the higher fee if you spend roughly $3,250 or more at Costco annually. Both prices have been unchanged since June 2023. There is no monthly payment option — it’s annual, paid upfront.
Yes — unconditionally. Costco Australia’s official membership policy states it will refund the membership fee in full, at any time, for any reason, if you are dissatisfied. No questions asked, no partial refund, no pro-rata calculation based on months remaining. This makes joining essentially risk-free: try it for three months, decide you’re not using it enough, and walk up to any membership counter and ask for your money back. This policy has been in place since Costco opened in Australia and has not changed.
The primary cardholder and one additional household member are included on every membership, at both the Gold Star and Executive tiers. Additional household members beyond the first can be added as extra cardholders for a fee. When you shop, your membership card must be scanned at the warehouse entrance — you cannot walk in without it. One important note: your Australian Costco membership card is valid at any Costco warehouse worldwide, so if you travel internationally, your card works at Costco locations in the United States, the United Kingdom, Japan, Canada, and all other countries where Costco operates.
On a per-unit basis for the items Costco stocks, yes — consistently. CHOICE compared 44 common grocery items and found Costco had the cheapest unit price on 33 of them, with Coles and Woolworths splitting the remaining 11. But the comparison only holds when you account for bulk pack sizes. Costco doesn’t sell a 500g bag of rice — it sells a 10kg bag. If you don’t have the storage or the household volume to use that quantity before it goes off, the per-unit saving disappears into waste. The categories where Costco reliably wins: meat, Kirkland Signature staples, cheese, cleaning products, over-the-counter medications, and fuel. Electronics and clothing are much more variable — check prices before you buy.
Yes — as of a recent policy change, Costco Australia’s food court now requires a valid membership card. The $3 hot dog and drink combo (which has famously never changed in price) is a members-only perk. Before this change, non-members could access the food court without entering the main warehouse floor; that is no longer the case at Australian locations. Pharmacy and optical services at Australian Costco warehouses do not require a membership to access, though member pricing is lower than non-member pricing at those departments.
Yes, with some important caveats. Costco Australia operates an online store at costco.com.au, but the product range is narrower than what you’ll find in-warehouse, and prices may differ. Delivery fees apply and can be significant on large or heavy items — which affects the value calculation. In February 2025, Costco launched same-day delivery in Australia through a delivery partner, available from select warehouses for orders meeting a minimum spend. The online store is better for big-ticket items like electronics and appliances than for groceries, where the delivery cost reduces or eliminates the per-unit savings you’d get in-warehouse. A membership is required for both online and in-warehouse shopping.
Aggressively, yes. Costco Australia currently operates 15 warehouses and has confirmed plans for 20 new stores over the next five years — which would more than double the current footprint. Two new warehouses are confirmed for 2027: a $74 million store in Pakenham, Victoria (Melbourne’s south-east), and a $33 million store in Alkimos in Perth’s northern suburbs. Site scouting is underway for additional locations including North and South Sydney, Adelaide, and a long-awaited first entry into Tasmania, which has never had a Costco warehouse. There are currently no Costco locations in Tasmania or the Northern Territory.
Executive Members earn a 2% reward on most eligible purchases made at Costco Australia — in-warehouse and online. The reward accumulates across your full membership year and is issued as a reward certificate when your membership renews. The certificate can be redeemed in-warehouse like cash, or applied against your renewal fee. The reward is capped at $1,000 per year. To earn back the extra $65 you pay for Executive over Gold Star through the reward alone, you need to spend $3,250 per year at Costco — roughly $270 per month. For households that shop regularly at Costco, this threshold is not difficult to reach. Executive also includes access to additional savings on Costco Travel packages.
Two plans, one question: is the extra $65 worth it? The math is cleaner than it looks.
The Gold Star membership at $65 per year ($5.42 per month) is what most Australians start with. It gives the primary cardholder and one nominated household member full access to every Costco Australia warehouse, the online store at costco.com.au, and all member-exclusive pricing including fuel stations, the food court, optical centre, pharmacy, and tyre centre. There is no annual reward attached to Gold Star — you save money through warehouse pricing, not a cashback mechanism. Gold Star is the right tier if you’re still working out whether Costco suits your household, or if your annual Costco spend is comfortably below $3,250. You can upgrade to Executive at any time at the membership counter.
Executive is the same as Gold Star in every practical way — same warehouse access, same fuel pricing, same food court — plus a 2% annual reward on eligible purchases, issued as a certificate at renewal. The extra $65 per year breaks even at $3,250 annual Costco spend (roughly $270/month). Households that do their regular grocery shop at Costco, fill up fuel weekly, and make occasional larger purchases (appliances, tyres, travel) typically hit that threshold without trying. The reward is capped at $1,000 per year, meaning it maxes out at $50,000 in annual Costco spending — well beyond most households. If your monthly Costco spend is already $250 or more, run the numbers before your next renewal — you’re almost certainly leaving money on the table by staying on Gold Star.
Costco Australia runs a referral program where both the referring member and the new member may receive a Shop Card when the new member signs up. For Executive Membership referrals, both parties may receive approximately $40 in Shop Card credit; for Gold Star and Business Membership referrals, both may receive around $20. Both the referring member and the new member must be present at the time of sign-up to qualify. Offer terms and amounts vary and can change — verify current details at the membership counter before signing up. If you know an existing Costco member, ask them about the referral offer before you join independently.

There are currently no Costco warehouses in Tasmania or the Northern Territory. Costco’s planned 20-store expansion over the next five years includes a confirmed first entry into Tasmania — a state that has long been requesting it — though a specific suburb and opening date have not yet been announced. Online shopping at costco.com.au is available Australia-wide, including Tasmania and NT, with delivery fees applicable.
The card gets you in the door. Here’s what’s worth your attention once you’re inside — and one benefit most members never take advantage of.
This is the single benefit that pays for the membership fastest for most Australian households. Costco fuel is typically 20–35 cents per litre cheaper than nearby service stations. For a household filling 50 litres per week, that translates to roughly $520–$910 in annual savings — comfortably more than the $65 annual fee. Before you join primarily for fuel, check that your nearest Costco location has a fuel station — Docklands in Melbourne does not. Costco posts live fuel prices on costco.com.au, so you can check before driving there. The fuel queues are real, especially on weekends and Friday afternoons; going on a weekday morning cuts wait time significantly.
Kirkland Signature is Costco’s house brand and one of the main reasons members keep renewing. Kirkland products sit alongside name brands on the shelf and are consistently priced 30–50% lower on a per-unit basis. The quality-to-price ratio is widely considered excellent — Kirkland olive oil, laundry detergent, toilet paper, nuts, and vitamins are members’ most frequently repurchased items. The Kirkland rotisserie chicken at $6.99 has become something of a cultural institution. Over-the-counter medications — antihistamines, paracetamol, vitamins — offer some of the most dramatic savings: a year’s supply of antihistamines runs around $30 at Costco compared to $20–$30 per box at a chemist. Switching to Kirkland across 10 common household staples saves the average family $40–$60 per month without changing habits — just the brand on the shelf.
These three departments are among the least discussed and most valuable parts of the Costco offer, especially for older members. The Hearing Aid Centre offers free hearing tests and hearing aids from approximately $1,899 per pair — compared to $6,000 or more at specialist hearing clinics. The Optical Centre provides prescription eyeglasses, sunglasses, and contact lenses at prices consistently below retail optical chains, with eye exams available through independent optometrists located within the Costco building. The pharmacy at Australian Costco locations offers prescription medications and over-the-counter products at competitive pricing. A single pair of hearing aids at Costco pricing can save over $4,000 compared to specialist clinic pricing — enough to pay the membership fee for more than 60 years.
Costco’s food court is not an afterthought — it’s a deliberate part of the member experience. The $3 hot dog and drink combo has famously never changed in price since Costco first introduced it. The food court is run near cost as a membership value signal: Costco’s own executives have publicly stated they will never raise that $3 price. Other food court items — pizza slices, sandwiches, Caesar salad, soft-serve — are similarly priced well below what you’d pay anywhere nearby. The food court now requires a valid Costco membership at Australian locations. If you’re making a warehouse visit with the family, budgeting $3 per person for lunch rather than stopping at a fast-food outlet on the way home is a practical benefit that adds up across a year of visits.
Beyond the warehouse floor, Costco Australia members have access to a tyre centre (competitive pricing on tyres with free rotation and balance after installation), Costco Travel (package holidays, car hire, and cruises with member-exclusive pricing), and a monthly Member Savings publication that lists instant discounts available in-warehouse that month. These discounts — typically $3–$12 off a specific item — are applied automatically at checkout when you buy the featured product; there are no coupons to clip and no codes to enter. Checking the Member Savings booklet before your visit and planning purchases around it is the single most effective way to compound your in-warehouse savings beyond everyday pricing. Members who ignore the monthly booklet leave a consistent stream of available discounts unclaimed.
The honest framework — not a promotional answer. Who saves money, who doesn’t, and what the maths actually looks like in practice.
Membership delivers reliable, measurable savings for households that match these profiles:
- Regular drivers within 30 minutes of a warehouse with a fuel station. Fuel savings alone — at 20–35c/L on 50 litres per week — comfortably recover the fee within a few months.
- Households of three or more people. The bulk pack sizes make sense when you have the people and the storage to use them. A family buying the same grocery staples they always buy, just in Kirkland Signature quantities, consistently saves 15–30% versus the supermarket equivalent.
- Members who use the Hearing Aid Centre or Optical Centre even once. A single set of hearing aids at Costco pricing versus specialist clinic pricing covers the membership fee for decades.
- Anyone who replaces regular chemist or supermarket OTC medication purchases with Kirkland equivalents. The per-unit savings on vitamins, antihistamines, and pain relief are dramatic on a full year’s supply.
Not everyone benefits, and the guide wouldn’t be honest without saying so:
- No warehouse within 30–40 minutes. Travel time and petrol costs to reach the warehouse erode the savings. An 80km round trip every two weeks isn’t a bargain — it’s a chore with a membership fee attached.
- Singles or couples in a small apartment. Bulk pack sizes lead to food waste or storage problems that cancel the per-unit savings. Buying 5kg of rice when you have nowhere to put it is not a deal.
- Disciplined ALDI shoppers. ALDI’s everyday pricing on staples competes directly with Costco’s bulk pricing on many categories, without requiring a membership fee or large pack sizes.
- Infrequent or irregular shoppers. Costco rewards consistency. If you visit twice a year, the membership math rarely works in your favour.
To work out whether membership pays for itself, the framework is simple. Assume you shop at Costco monthly and save 20% on average versus Coles and Woolworths on the same products. At $200/month in Costco purchases, you’re saving roughly $40/month — or $480 over the year — against the $65 membership fee. Add fuel savings (even at a conservative 20c/L on 40 litres/week), and you’re adding another $416. Total benefit: approximately $896 against a $65 fee. The fee pays for itself in most realistic shopping scenarios within the first one or two visits. The calculation breaks down when distance to the warehouse is factored in — a 60km round trip once a month at current petrol prices costs roughly $15–$20 in fuel and an hour of your time, which materially changes the arithmetic for households that don’t live close.
Things experienced members know that the website doesn’t tell you.
Costco on a Saturday afternoon is a fundamentally different experience from Costco on a Tuesday morning. Weekday mornings — particularly Tuesday through Thursday before noon — have shorter queues at the fuel station, faster checkout, and fully stocked shelves. Clearance shelves (which appear without announcement and often feature 50%+ markdowns on specific items) tend to get restocked before the day crowd arrives. If you’re retired or work flexible hours, a mid-week morning visit covers more ground with less stress than fighting weekend crowds. The food court is also faster during off-peak hours, which matters when you’re parking a trolley the size of a small car.
Costco uses a consistent price-tag system that members who know it use to find the best deals. A price ending in .97 (e.g., $14.97) indicates a manager markdown — the warehouse is clearing stock, it won’t be reordered, and when it’s gone, it’s gone. These are not announced anywhere; you find them by walking the aisles. A price ending in .00 or .99 is standard member pricing. A small asterisk (*) in the upper right corner of a price tag means the item is being discontinued and will not be reordered — buy it now or you won’t see it again. Building a list before you enter and sticking to it prevents impulse purchases, but scanning for .97 tags on your way around is a legitimate strategy for finding unannounced bargains.
Costco releases a monthly Member Savings booklet — available on the Costco Australia website and app, and in physical form at the warehouse entrance — listing all items with instant member discounts that month. These are not coupons to clip; the discount applies automatically at checkout when you buy the featured product. Discounts typically range from $3 to $12 off a specific item. Reviewing this booklet before you drive to the warehouse and adding featured items to your shopping list if you already needed them is the easiest available way to compound your savings without changing shopping habits. Many members who don’t check it miss consistent savings on items they’d have bought anyway.
Costco is not cheaper on everything, and treating it like it is leads to overspending. The consistent winners at Costco Australia are: meat (mince at ~$9.99/kg, steaks frequently half the supermarket price), Kirkland household staples (olive oil, toilet paper, laundry detergent), cheese, OTC medications, vitamins and supplements, fuel, and baked goods. Variable categories where you need to compare prices first: electronics, clothing, and branded groceries that go on heavy special at Coles and Woolworths regularly. Coles and Woolworths half-price specials on branded products can and do beat Costco’s everyday price on specific items — knowing your prices on the things you buy regularly is worth the ten minutes it takes once.
Costco Australia’s official return policy for merchandise is that Costco will refund the purchase price at any time on most products for change of mind — with no receipt required, no time limit, and no questions asked. Exceptions apply to certain electronics (purchased on or after August 31, 2020), which must be returned within 90 days of purchase. For most other products — groceries, household goods, clothing, and more — the return policy is open-ended. This is not just a nice-to-have; it’s a genuinely unusual policy that covers situations where a bulk-buy product doesn’t work for you, or you bought more than you needed. It also reflects Costco’s consistent philosophy: if a member is dissatisfied, Costco prefers to deal with it than to lose the membership renewal.
A family of four or more with children at home is Costco’s ideal member. The bulk quantities that are overkill for a couple become routine consumption for a household going through cereal, laundry detergent, toilet paper, meat, and snacks at a family pace. The CHOICE research finding — Costco cheapest on 33 of 44 items — was measured on unit prices that only make financial sense if you can use the quantity. Large families can. Add fuel for the family car and the savings are compound. Gold Star at $65 is the right starting tier for families; if you find you’re spending $270 or more per month at Costco within the first few months, upgrade to Executive at your next renewal to start earning the 2% reward on that spend.
This is the hardest demographic case for Costco to make, and the guide won’t pretend otherwise. Single-person households face a genuine bulk-size problem: you either buy less frequently (but Costco’s fresh food has a shelf life), or you split purchases with a friend or neighbour. The splitting strategy works well — one Costco membership shared between two households who split bulk purchases has the economics of a shared monthly subscription. The strongest single-person use cases are: non-perishable Kirkland staples (olive oil, toilet paper, vitamins, laundry products that last indefinitely), fuel if you drive regularly, and optical or hearing services where even a single annual visit delivers significant value. If none of those three categories apply to your life, the $65 is genuinely hard to justify as a solo shopper.
Distance is the main killer of Costco value. If the nearest warehouse is 60 minutes away, a monthly shopping trip consumes two hours of travel time and costs $15–$20 in petrol to reach — before you’ve bought anything. That changes the break-even calculation significantly. The online store at costco.com.au is available anywhere in Australia and may be the better option for members who don’t live near a warehouse, though delivery fees reduce the savings on grocery items specifically. The practical test: if you pass a Costco on a regular route — commuting, visiting family, driving to sport — the travel cost is zero and the membership works. If every visit is a dedicated 90-minute round trip, you need to spend significantly more per visit to justify the economics. The good news: 20 new warehouses over five years means the nearest location is likely to get closer.
Often yes, and for reasons retirees don’t always realise. Fuel savings work the same regardless of age or income. The Hearing Aid Centre is particularly valuable — at $1,899 per pair compared to $6,000 or more at specialist hearing clinics, a single pair of Costco hearing aids covers the membership fee for 62 years at $65/year. The Optical Centre’s eyeglass pricing is consistently below retail chains. OTC medications and vitamins in Kirkland quantities are dramatically cheaper than monthly chemist runs. Retirees with the flexibility to visit on weekday mornings get the best experience — shortest queues at both the entrance and the fuel station. The main risk for retirees is over-buying perishables in bulk — stick to the non-perishable Kirkland staples, fuel, and health services, and the $65 is typically well-justified even on a modest spend level.
Yes — and it costs you nothing to try, because of the unconditional refund policy. Join online at costco.com.au or in-warehouse for $65. Do your first two or three shops and fill up fuel a handful of times. At the end of three months, if the savings haven’t clearly exceeded $65, walk to the membership counter and ask for a full refund. You’ll receive it with no argument and no penalty. The risk profile on trying a Costco membership is genuinely zero — if it works for your household, you keep going; if it doesn’t, you get every cent back. The only reason not to try it is if there genuinely isn’t a warehouse within a reasonable drive of where you live — in which case watch the expansion announcements and revisit when a new location opens near you.
