Each Australian state and territory runs a Real-Time Prescription Monitoring system that records dispensings of Schedule 8 medicines and selected Schedule 4s (benzodiazepines, z-drugs, gabapentinoids, quetiapine, codeine combinations, tramadol — varies by state). Prescribers and pharmacists can query the system before writing or dispensing a script to see the patient's recent monitored-medicine history and any harm-risk alerts. The systems do not prevent prescribing — the decision remains clinical. The federal National Data Exchange (NDE) is progressively linking state systems for cross-border lookup. Tasmania was first (DORA, 2009); Western Australia (ScriptCheckWA) was last to go live, completing coast-to-coast coverage.

In mandatory-check states, the legal obligation is to check the system before prescribing or dispensing a monitored medicine. This is commonly misunderstood as:
| Common assumption | What the legislation actually says |
|---|---|
| "If I see red alerts, I can't prescribe" | You can still prescribe — the system supports your decision, it doesn't override it. Document your clinical reasoning, particularly when proceeding despite alerts. |
| "If I don't check, I get prosecuted" | Most state regulators take a risk-based, education-first approach. Penalties (where they exist) apply to repeat or egregious non-compliance. Queensland Health, Victorian DHHS and SA Health all describe this approach in their published frameworks. |
| "Mandatory means every script" | Yes — every prescription and every dispense of a monitored medicine triggers the check requirement, with state-specific exemptions (typically hospital, palliative, aged care, prison, emergency). |
| "Pharmacy will check, so I don't have to" | The check is required at both prescription and dispensing in mandatory states. The two checks serve different decision points. |

All RTPM systems monitor all Schedule 8 medicines (the consistent part across states). What varies is which Schedule 4 medicines are added to the monitored list.
Authority required: The exact S4 list changes when state regulators update their monitored-medicine determinations. Pregabalin and gabapentin are increasingly added across jurisdictions due to overdose evidence. For prescribing compliance, always check the current monitored-medicine list on the state regulator's page.

The NDE is the Commonwealth interoperability layer that allows state RTPM systems to share dispensing data. Once a state's integration with NDE is active, prescribers checking their state's system can see dispensings recorded by other states.
Practical implication for locums and border-area practices: Check your current state's RTPM. The NDE link should display interstate dispensings where the integration is live. Coverage isn't always complete for older prescriptions or states with newer integrations — when in doubt, ask the patient about prescriptions filled interstate and verify against any documentation they have.

| RTPM (e.g. QScript, SafeScript) | PBS Authority | |
|---|---|---|
| Purpose | Harm reduction — identify patients at risk based on prescribing history | Commonwealth subsidy — confirm patient meets PBS criteria so the script is subsidised |
| Administered by | State health department | Services Australia (Commonwealth) |
| What it captures | All dispensings of monitored medicines (S8s + specified S4s), regardless of PBS status | Only prescriptions billed under PBS |
| Outcome of check | Clinical decision support — alerts, history, prescriber pattern | Approval number that allows PBS subsidy |
| Required when? | Before prescribing/dispensing a monitored medicine (in mandatory states) | Before writing a script for an Authority-listed item if PBS subsidy is wanted |
Often both apply to the same script. An S8 like long-term oxycodone may require checking your state's RTPM (harm reduction) and obtaining PBS Authority (Commonwealth subsidy). They are separate processes administered by different bodies — completing one does not satisfy the other.
