PBS restriction levels, explained
Your prescribing software shows a label next to the medicine — Restricted Benefit, Authority Required, or Authority Required (STREAMLINED) — and you need to know what to actually do. Pick the label below and find out. A quick reference for GPs, registrars and internationally trained doctors.
Source: PBS Schedule, Section 1.2 Explanatory Notes — Prescribing Medicines for PBS Prescribers (Australian Government Department of Health, Disability and Ageing), page last updated 17 June 2025. General information for prescribers — not clinical, legal or billing advice. Always confirm the exact restriction wording and the current streamlined authority code in the live PBS Schedule or your prescribing software, as indications and codes change. State and Territory drugs-of-dependence laws apply in addition to PBS rules.
The three (really four) categories at a glance
Unrestricted — no restriction on therapeutic use. Prescribe as a standard PBS item.
Restricted Benefit — PBS-subsidised only for the indication listed in the Schedule. No approval, no code — but the use must match the restriction.
Authority Required — a restricted benefit that needs prior approval from Services Australia or DVA before it can be dispensed on the PBS.
Authority Required (STREAMLINED) — a restricted benefit that needs no call or prior approval, but you must record the streamlined authority code.
Prescription mechanics — forms, item limits, prescriber number
- Up to three items may be written on one standard PBS prescription form. Authority Required, Authority Required (STREAMLINED) and optometrist items must be written one item per form.
- Use your prescriber number, not your provider number, on PBS prescriptions.
- Authority approvals cannot be retrospective — an Authority Required script is not valid until approved, and the approval number must appear on the form.
- For a Streamlined item, keep your prescriber copy for 12 months (recording daily dose, the condition, clinical justification, the patient age if a child, and any previous authority).
- If the patient’s use falls outside the restriction, it cannot be PBS-subsidised — write a private (non-PBS) prescription and strike out the PBS/RPBS text.
Urgent / telephone supply & Regulation 49
Urgent supply: where State or Territory law allows, you may phone the pharmacist to supply, then forward the written prescription within seven days. For an Authority Required item this only applies once prior approval has been given, and the approval number must be on the follow-up script.
Regulation 49 (formerly Regulation 24): original and all repeats may be supplied at once if you are first satisfied that the maximum quantity is insufficient and the patient has a chronic illness or limited remote access and would suffer great hardship obtaining supplies separately. Endorse the script “1 supply”.
How to lodge an Authority application
- Online: the Services Australia PBS Authorities system, via your HPOS account.
- Phone (Services Australia): 1800 888 333.
- Phone (DVA / RPBS): 1800 552 580.
- Increased quantities or repeats are generally approved for about one month per supply, repeatable to roughly six months total where clinically appropriate and consistent with the listed indication.
