Walking into Costco for the first time feels a little overwhelming in a good way. Oversized trolleys, bulk everything, and aisles that seem to go on forever.
But before you can even experience it, there’s one important decision to make: Is the membership actually worth paying for?
Costco Membership Prices in Australia
Costco keeps things relatively simple with two membership tiers.
The Gold Star Membership costs around $65 per year, while the Executive Membership is about $130 per year.
Both options give you full access to warehouses, fuel stations, and online shopping.
The key difference is that Executive members earn 2% cashback on eligible purchases, which can make a significant difference depending on how much you spend.
Which Membership Is Right for You?
For someone who shops occasionally or just wants to try Costco, the Gold Star Membership is usually enough.
However, for families or households that regularly buy groceries, petrol, and household essentials in bulk, the Executive Membership can start to make more sense.
If you spend around $6,500 per year, the 2% reward gives you $130 back, effectively covering the cost of the membership.
For many families, especially those buying diapers, cleaning supplies, and groceries in bulk, this amount can be reached more easily than expected.
Why People Keep Renewing Their Membership
What keeps people renewing their membership year after year is not necessarily buying everything at Costco, but buying a few key items that consistently offer value.
The rotisserie chicken is one of the most well-known examples, affordable and reliable.
Bulk household essentials like toilet paper and paper towels are another common purchase, along with meat, fresh produce, bakery items, and vitamins.
These are the items where the savings feel the most noticeable and practical, and often enough to justify the membership on their own.
Petrol Savings: Valuable, But Not for Everyone
One of the biggest selling points for many members is Costco’s petrol, which is often priced lower than nearby stations.
For people who drive frequently, this alone can justify the membership over time.
However, this benefit really depends on individual habits. Personally, I don’t tend to benefit as much from Costco fuel because I don’t drive often and I don’t usually use E10 or premium petrol or diesel.
This highlights an important point: the value of a Costco membership is highly dependent on how you live and what you actually use.
The Food Court: A Surprisingly Affordable Bonus
Another underrated perk is the Costco food court. It offers simple, affordable meals like hot dog and drink combos or pizza at prices that are hard to beat. It’s not fancy, but it is convenient, filling, and budget-friendly.
For families, it can turn a regular shopping trip into a low-cost outing, adding value beyond just groceries.

The Downside: It’s Easy to Overspend
Costco is known for savings, but there is also a hidden downside.
Because everything is sold in bulk and often feels like a good deal, it’s very easy to overspend.
You might walk in intending to buy one or two items and leave with a full trolley.
While the price per unit may be cheaper, your total spending can increase if purchases are not planned carefully.
Costco doesn’t automatically save you money, it requires discipline and intentional shopping.
What People Don’t Always Realise Before Joining
One thing that surprises many first-time shoppers is that Costco has a very limited range compared to traditional supermarkets.
You won’t find ten different brands of the same product.
Instead, Costco focuses on a smaller selection at competitive prices.
This means you may still need to shop at places like Coles or Woolworths for specific items.
Costco works best as a supplement to your regular grocery shopping, not always a complete replacement.
How Costco Affects Supermarket Prices
Costco’s impact goes beyond individual savings.
By offering competitive pricing, it puts pressure on major supermarkets like Coles and Woolworths to keep their prices reasonable.
This competition leads to more promotions, better deals, and improved pricing across the market, even for people who don’t shop at Costco regularly.
Without competitors like Costco, supermarkets could have more control over pricing and product selection.
Costco helps maintain balance by offering an alternative shopping model, challenging traditional pricing strategies, and giving consumers more choice.
In the long run, this competition benefits everyone.
Quick Summary
- Costco membership costs $65–$130 per year
- Executive membership offers 2% cashback
- Best value comes from a few key items
- Petrol savings depend on your driving habits
- Easy to overspend without planning
- Works best alongside regular supermarkets
Final Thoughts
Whether a Costco membership is worth it ultimately comes down to your lifestyle.
For some households, the savings on bulk items and petrol make it an obvious choice.
For others, the value may come from just a few key purchases or occasional visits.
Understanding your own shopping habits is what makes the biggest difference.
Costco can be a powerful way to save money, but only if you approach it with intention rather than impulse.
