Why Is My Prescription Cheaper at Another Pharmacy?

Why the same script costs different amounts at different pharmacies

Three numbers govern almost every pharmacy price in Australia:

• The PBS dispensed price (set federally for the medicine)
• The standard co-payment (general $25, concessional $7.70 in 2026)
• Any brand premium attached to the specific brand of medicine you choose

For a PBS-listed medicine at the standard co-payment, all three numbers are fixed nationally. Where pharmacies legally differ on the same PBS script, the differences are:

• The pharmacy chose to absorb up to $1 of the PBS co-payment as a discount
• The medicine's actual dispensed price is below the co-payment, so the pharmacy charges the real price
• You are filling a different brand of the same medicine at two pharmacies, and the brand premium varies
• You are filling a private (non-PBS) script, in which case the price is fully market-set

The next four sections cover each in turn.

The $25 PBS co-payment is a ceiling, not a floor

A common misunderstanding: the PBS general co-payment of $25 is the maximum a pharmacy can charge for a PBS-listed medicine at the standard rate. It is not a fixed amount. The pharmacy can charge less if the underlying price is lower.

Two specific cases bring the price under $25:

• Below co-payment medicines: many older off-patent medicines now have a dispensed price below $25. The pharmacy charges the actual dispensed price, not the full $25. The same medicine at a different pharmacy may have a different actual price (within a small range), because each pharmacy's wholesale and dispensing margins differ slightly.
• Pharmacy discount: since 1 January 2016, federal rules let pharmacies discount the PBS co-payment by up to $1 per script. From 1 July 2024 this was extended to allow discounts on both general and concessional co-payments.

If a script "should" be $25 but you paid $24 at one pharmacy and $25 at another, the $1 difference is the legal discount one pharmacy chose to apply.

Pharmacies can discount below the co-payment (within the rules)

The federal $1 discount rule applies to PBS-listed prescriptions where the dispensed price would be at or above the co-payment. The mechanics:

Patient type	PBS co-pay ceiling	Discounted floor
General	$25.00	$24.00
Concession	$7.70	$6.70

The discount is optional. Individual pharmacies decide whether to apply it. Some chains apply it everywhere, some apply it on selected medicines, some not at all.

A point that catches people out: the discounted portion does not count toward your PBS Safety Net threshold. If a pharmacy discounts by $1, only the amount you actually paid (the discounted price) accumulates toward the Safety Net. Over a year of regular scripts, the difference can be meaningful. For someone close to the threshold who wants to reach it, paying the full co-payment at one pharmacy may put them there faster, even though each script costs $1 more.

The discount cap rule

Federal rules cap the pharmacy discount at $1 per script. A pharmacy advertising a "PBS script for $19" on a standard $25 medicine is either:

• Discounting on a private (non-PBS) script (different rules apply)
• Selling a below co-payment medicine where the actual dispensed price is $19 anyway
• Advertising the price of a script that isn't PBS-listed at the standard general rate

Be specific when comparing pharmacies. The headline rate is meaningful only if both pharmacies are talking about the same script, the same brand, and the same PBS status.

Private prescriptions vary more wildly

Private prescriptions (non-PBS) are not subject to a federal co-payment ceiling. The pharmacy sets the price based on the wholesale cost of the medicine, dispensing time, and the pharmacy's margin. Two pharmacies in the same suburb can quote prices that differ by 20 to 50 per cent on the same private script.

A private prescription is most common when:

• The medicine is not listed on the PBS at all
• The medicine is PBS-listed but only for specific clinical indications (your indication doesn't qualify, so the prescription is written as private)
• The medicine is PBS-listed but the prescriber chose to write it private for an administrative reason

For private scripts, shopping around is legitimate and worthwhile. Some online pharmacies and dispensaries quote significantly lower private prices than community pharmacies in metro areas. Make sure you are comparing the same brand and the same pack size. A 30-tablet pack at one pharmacy and a 60-tablet pack at another are not the same price.

When shopping around makes sense

There are situations where it pays to compare pharmacies. Be honest about what you are paying for.

• Private (non-PBS) prescriptions: prices can vary by tens or hundreds of dollars. Worth calling two or three pharmacies before you fill.
• Below co-payment medicines: small differences ($2 to $5) can accumulate over a year of regular scripts. Less worth the time on a single script.
• Brand premium decisions: if a brand premium is $15 per script and you are filling it monthly, that is $180 a year that is not subsidised. The premium is set by the original manufacturer, but switching to a TGA-approved generic at the same pharmacy removes it. See our guide on generic vs brand medicines for the rules.
• One-off bulk fill of a private medicine: a single comparison call can save real money.

When it doesn't (the transfer-friction reasons)

Shopping around can cost you in less visible ways. Before transferring a regular script to a new pharmacy, consider:

• Safety Net tracking: if all your scripts have been filled at one pharmacy, the Prescription Record Form is up to date and easy to read. Splitting across pharmacies means each holds a partial record. Services Australia and the central PBS log catch up, but it can take longer to confirm Safety Net status.
• Medication reconciliation: one pharmacist seeing all your medicines together is in a better position to catch interactions, duplications, and dose changes. This is especially important if you are on five or more regular medicines or if you have recently been discharged from hospital.
• Webster pack continuity: if you use a Webster pack or dose administration aid, switching pharmacies mid-cycle is disruptive. The new pharmacy needs the full list, the GP referral if relevant, and time to set up.
• Continuity of care for chronic conditions: a regular community pharmacy that knows your history can flag changes faster than a new pharmacy seeing you cold.

For occasional savings on a non-recurring private script, shopping around is straightforward. For your regular medicines, the cost of fragmenting your dispensing history is usually higher than the dollar saving.
