The PBS Safety Net, the early supply rule, and why we built Safety Net Insights

The PBS Safety Net is one of the most useful things in the Australian healthcare system. It's also one of the hardest to keep track of.

We say that with feeling, because some of the screenshots in this post are real scripts from our founders' phones. We use Scripty too. We hit the same things our users hit.

So this post is part explainer, part real talk – on what the PBS Safety Net actually is, why the early supply rule trips so many people up, and what we're trying (and still figuring out how) to do about it.

What is the PBS Safety Net?

The PBS Safety Net is a federal government program that lowers the cost of your prescription medications once you and your family hit a certain spending threshold within a calendar year.

In short: spend a certain amount on PBS scripts in a year, and your future scripts get cheaper for the rest of that year. The threshold resets every 1 January.

A couple of things that often surprise people:

The threshold is per family, not per person. Spouses and dependants under 16 (or full-time students under 25) can pool their PBS spending against one Safety Net threshold. Worth registering as a family if you haven't.
The threshold can change every year. It doesn't always stay where you left it – the general patient threshold for 2026 is $1,748.20, while the concessional threshold remains at $277.20. So if you hit it in December, you'll start fresh in January at the new amount.

The bit that's hard to see: the early supply rule

Some PBS medications have what's called an early supply rule (also known as the "20-day rule" or "50-day rule," depending on the medication).

It works like this:

Your script gets dispensed.
The system records the date.
If a refill happens before the rule allows (usually 20 days, sometimes 50 days for 60-day prescriptions), that next fill may not count toward your Safety Net threshold.

You can still get the medication. The pharmacy can still dispense it. But that fill won't tick up your Safety Net total – which means you might miss out on the cheaper script price you were working toward.

The hard part? This rule isn't on your prescription. It's not somewhere you can easily look up. Pharmacists know about it because they deal with it every day. For most consumers, it's invisible.

Here's how it shows up in Scripty's ordering screen.

How safety net early supply shows up for Scripty users

The most common way our users run into this is through their pharmacist – not us. Pharmacists usually pick up on it when they're processing the order, and reach out to the patient to check whether they really need the refill now or whether it can wait.

It's a moment of friction that nobody really wants. The pharmacist has to make the call, the patient gets a confusing message, and sometimes the order doesn't go through.

It's not anyone's fault. The pharmacist is doing their job. The patient often had no way of knowing. The information just wasn't visible at the time it would have been useful. We tried to close the gap.

What we built

We'll be upfront: Safety Net Insights is a first attempt at this.

It does two things today:

Inside each script, it flags whether the medication is subject to the 20-day or 50-day early supply rule, and shows the earliest date your next fill is likely to count toward your Safety Net.
On your active scripts, when you go to order, the same information sits front-and-centre – so you have it before you place an order, not after.

The bit at the bottom of the script. It's based on your last dispensed date and the current PBS list.

It's not magic. We use the data we have – your last dispensed date and the PBS early supply rules – to suggest a refill date. If we don't have the last dispensed date (which can happen), we can't calculate it. Your pharmacist always has the most current information.

It's also worth saying out loud: the date is a guide, not a restriction. You can refill whenever you need to. If you do refill early, that fill may not count toward your Safety Net – but you won't be blocked from getting your medication.

There's a lot more we'd love to do here. Showing more about your Safety Net journey across the year. Family-pooled views. A clearer picture of where you're at, not just whether your next fill counts. We're not there yet – but we're listening, and we'll keep building.

Why safety net matters to us

We build Scripty for a community we're part of.

A few of the screenshots in this post are real scripts from our founders' phones. We use it. Our families use it. The friction points our users run into – we run into them too.

Safety Net Insights is shaped by feedback from Scripty users and pharmacists. It's also shaped by our own everyday experience of trying to keep track of what's going on with our scripts.

This is a first step. We've got more we want to show – and we'll keep building it with our community, not just for them.

Got questions about Safety Net Insights or the PBS Safety Net? Your pharmacist is always your best first stop. They know your medications, they know the rules, and they're often the unsung heroes of this whole system.

Safety Net Insights provides general information only based on your scripts and the PBS list. It is not medical advice and may not reflect your exact PBS Safety Net status. Always consult your pharmacist or doctor for advice specific to your circumstances.
