Why is my prescription cheaper at another pharmacy?

The same prescription can cost different amounts at two pharmacies on the same street, and the difference comes down to a handful of factors. Part of the price is fixed by the federal government, and part of it is left to the pharmacy.

For a medicine listed on the Pharmaceutical Benefits Scheme, or PBS, the government sets the most you can be charged. From 1st January 2026 that maximum is $25.00 for a Medicare card holder and $7.70 for someone with a concession card, according to the Department of Health, Disability and Ageing. The name for that amount is the co-payment.

The point people miss is that the co-payment is a ceiling, not a set price. A pharmacy can charge less, and several situations bring the real price below it. When two pharmacies quote you different amounts, the gap almost always comes from one of four places: a medicine that already costs less than the co-payment, a brand premium, a private prescription that is not on the PBS, or an optional discount the pharmacy chose to apply.

The PBS co-payment is a maximum, not a fixed price

For a PBS medicine, the Australian Government subsidises the cost and you pay the rest up to the co-payment. The Pharmaceutical Benefits Scheme confirms that from 1st January 2026 a general patient pays up to $25.00 and a concession card holder pays up to $7.70, with the government covering the remaining cost of the medicine, aside from brand premiums and a few other allowable charges.

Because it is a maximum, the co-payment is the same nationally, but the amount you actually hand over is not always the full figure. Two pharmacies can both be following the rules and still charge different totals for the same script.

Why the same PBS script can still cost less

The most common reason is a medicine that already sits below the co-payment. Many older, off-patent medicines have a dispensed price under $25.00, so you pay that lower price rather than the full amount. The Department of Health notes that when a medicine costs less than the full co-payment, it is subject to normal retail pricing, which can vary depending on where you fill it. The differences here are usually small, because each pharmacy's wholesale cost and dispensing margin only move the price a little.

The second reason is an optional discount. Pharmacists have long been able to take a small amount off the co-payment, but that discount is being reduced. The Pharmaceutical Benefits Scheme explains that for Medicare card holders the optional discount was removed from 1st January 2026, so a general script now sits at the full $25.00 maximum. For concession card holders it reduces a little each year until it reaches zero in 2030, with up to 60 cents off the $7.70 co-payment through 2026. Whether a pharmacy applies it at all is its own choice, so a concession script might cost about $7.10 at one pharmacy and $7.70 at another.

One detail surprises people near the end of the year. Only the amount you actually pay counts toward your PBS Safety Net, and the Pharmaceutical Benefits Scheme confirms that once you reach the threshold, further PBS medicines are charged at the concession rate for general patients or dispensed at no further charge for concession card holders for the rest of the calendar year. A discounted script therefore moves you toward that threshold slightly more slowly, so if you are close to it, paying the full co-payment can get you there sooner.

Brand premiums add a cost the government does not cover

A brand premium is an extra amount charged by the maker of a particular brand, on top of the standard price. The Department of Health advises that if you choose a medicine with a brand premium, you pay that premium on top of the co-payment, and the premium does not count toward your PBS Safety Net. Choosing an equivalent generic version, which works the same way and is usually cheaper, avoids the premium.

This is where two pharmacies can legitimately differ on what looks like the same medicine. If one dispenses the premium brand and the other a generic, the prices will not match, even though the PBS listing behind them is the same.

Brand versus generic

A generic usually clears the premium

Ask whether an equivalent generic is available. It works the same way, is usually cheaper, and often removes the extra brand cost at the same counter.

Private prescriptions are not capped

A private, or non-PBS, prescription sits outside the co-payment system, so no federal maximum applies. The pharmacy sets the price from the wholesale cost of the medicine, the dispensing work involved and its own margin, which is why two pharmacies can quote noticeably different amounts for the same private script. Our guide on private versus PBS prescriptions explains when a script is written privately and why.

A prescription is usually private when the medicine is not listed on the PBS, when it is listed only for specific conditions that do not apply to you, or when the prescriber writes it privately for an administrative reason. Because private prices are uncapped, a comparison between pharmacies can make a real difference here. A price comparison only holds when it is the same brand and the same pack size, because a 30-tablet pack and a 60-tablet pack are not the same purchase. If you decide to fill it somewhere else, our guide to prescriptions in Australia covers how to move a script between pharmacies.

What is capped and what is not

The split between the two is easiest to see side by side.

When comparing pharmacies is worth it

A few situations make the extra calls worth it, and the Department of Health itself suggests speaking with your pharmacist about the cost and comparing prices, including online. Private prescriptions are the clearest case: prices are uncapped and can differ by a lot, so a call to two or three pharmacies before you fill can save real money. Medicines that already sit below the co-payment vary only a little per script, so the saving is minor on a single fill, though it accumulates over a year of regular repeats. Brand premiums are worth raising with your pharmacist, because an equivalent generic at the same counter often removes the extra cost. And a 60-day prescription, where your doctor decides it suits your condition, gives you twice the medicine for one co-payment, which lowers the cost per day.

Before you fill

A quick call pays off on private scripts

Private prices are uncapped, so two or three quotes before you fill can turn up a real difference on the same brand and pack size.

When staying with one pharmacy is worth more

Spreading your scripts across pharmacies to chase small savings can cost you in less obvious ways. Safety Net tracking is simpler when one pharmacy holds your record, because splitting scripts means each holds only part of it, and confirming your Safety Net status can take longer. Medication review works better when one pharmacist sees all your medicines together and can flag interactions, duplicates or dose changes, which matters most if you take several regular medicines or have recently left hospital. Continuity of care from a pharmacy that knows your history means changes get noticed faster than at a counter seeing you for the first time. And dose administration aids, like a weekly blister pack, are disruptive to move mid-cycle, because the new pharmacy needs your full list and time to set it up.

For a one-off private script, comparing prices is straightforward and can save real money. For your regular medicines, the cost of fragmenting your dispensing history is often higher than the dollar saved.
