Schedule 8 (controlled drug) prescribing rules differ by state and territory. This is a compass â it points you to the authoritative source for each jurisdiction, summarises the general shape of the rules, and flags what to watch for. It's not a substitute for the state-specific regulations.
â ī¸ Verify current rules with your state health department before prescribing. S8 prescribing rules change and this page may lag official sources. Every jurisdiction has its own permit thresholds, exemptions, and real-time monitoring systems. Direct links to each are below.
Quick concepts
Two different regulatory streams apply to S8 prescribing in Australia:
1. Drug-dependent patient permits â a specific authorisation required to prescribe S8 medicines to a person who is drug-dependent. Managed by each state's health department. Rules differ significantly between jurisdictions on what triggers the requirement.
2. Real-time prescription monitoring (RTPM) â mandatory real-time checking of S8 (and some S4D) prescriptions before writing. All Australian states and territories now have RTPM systems in place (SafeScript, QScript, ScriptCheckWA, and equivalents). The systems are separate from permits but sometimes integrated.
Some prescribing scenarios trigger both. Some trigger only one. A few (e.g. short-term post-surgical opioid prescribing to a non-dependent patient) may trigger neither. The details are where the danger lives â check the specific rules before you write.

đ´ Queensland
S8 permit / approval
Approvals to prescribe controlled drugs are managed under the
Medicines and Poisons Act 2019. Certain scenarios (including prescribing to drug-dependent persons) require approval from QLD Health.
Medicines and poisons â QLD Health
Application
Via the Regulated Drugs Portal (or successor system) as directed by QLD Health.
Key watch-outs
Different rules apply to opioid dependency treatment (methadone/buprenorphine) vs general S8 prescribing to dependent patients. Check current guidance before starting a new patient on either.
đ New South Wales
S8 authority
Authorities under the
NSW Poisons and Therapeutic Goods Act 1966. Section 28 authority is generally required to continue prescribing S8 medicines to a patient beyond 2 months or to a drug-dependent person.
NSW Health â prescribing restricted medicines
Application
Pharmaceutical Services Unit â form and process on the NSW Health website (link above).
Key watch-outs
The 2-month rule triggers Section 28 authority independently of dependency status. Opioid dependency treatment (OTP â Opioid Treatment Program) has separate authorisation requirements.
đī¸ Victoria
Real-time monitoring
SafeScript Victoria â the original SafeScript. Mandatory to check before prescribing or dispensing monitored medicines.
safescript.vic.gov.au
S8 permit
Permits required under the
Drugs, Poisons and Controlled Substances Act 1981. A permit is required to prescribe an S8 medicine to a drug-dependent person, or to prescribe an S8 medicine for longer than 8 weeks.
health.vic.gov.au/drugs-and-poisons/permits
Application
Via the Medicines and Poisons Regulation system or online permits portal â see current link on the VIC Health page above.
Key watch-outs
The 8-week threshold triggers a permit requirement independent of dependency. Pharmacotherapy (methadone/buprenorphine for opioid dependency) requires separate accreditation.
đ South Australia
S8 authority
Authorities under the Controlled Substances (Poisons) Regulations 2011. DASSA (Drug and Alcohol Services SA) reviews applications for prescribing S8 medicines to drug-dependent persons.
Application
Via DASSA and the SA Health authorisation process. See the SA Health page above for current forms.
Key watch-outs
Opioid substitution therapy requires DASSA authorisation and prescriber accreditation.
đī¸ Western Australia
S8 authority
Authority under the
Medicines and Poisons Act 2014. The Medicines and Poisons Regulation Branch administers approvals for prescribing S8 medicines to drug-dependent persons and for extended prescribing.
WA Health â Medicines and Poisons Regulation
Application
Via the WA Health Medicines and Poisons Regulation Branch â forms on the WA Health site.
Key watch-outs
Community Program for Opioid Pharmacotherapy (CPOP) is the pathway for opioid dependency treatment prescribers.
đī¸ Tasmania
S8 authority
Authority under the Poisons Act 1971 (Tas). Authorities required for extended S8 prescribing and for prescribing to drug-dependent persons.
Application
Via the Pharmaceutical Services Branch, Tas Department of Health.
Key watch-outs
Tasmania has historically had unique arrangements around some controlled substances (including medicinal cannabis). Verify current process.
đī¸ ACT
S8 authority
Authority under the ACT Medicines, Poisons and Therapeutic Goods Act 2008. Approvals required for prescribing S8 medicines to drug-dependent persons and for extended use.
Application
Via ACT Health's Chief Health Officer's delegate. See the ACT Health page above.
Key watch-outs
ACT process has historically integrated with NSW pharmaceutical services for some functions â check current arrangement.
đĩ Northern Territory
S8 authority
Authority under the NT Medicines, Poisons and Therapeutic Goods Act 2012. Notifiable Drug Permits (or their successor) required for certain S8 prescribing situations.
Application
Via NT Health's Medicines and Poisons Control unit.
Key watch-outs
Remote and Aboriginal Community Controlled Health Service settings often have specific delegation arrangements.
Universal practical principles
These apply regardless of jurisdiction:
- Check RTPM before writing every S8 (and monitored S4D) prescription. The systems are mandatory in most states and best practice everywhere. Document that you checked.
- Assume dependency risk in new patients requesting S8. Ask about prior use, prior prescribers, and check RTPM before prescribing. New-patient S8 requests are the highest-risk scenario.
- Written treatment agreements for ongoing S8 prescribing are widely recommended. Content typically includes: single prescriber, single pharmacy, no early scripts, no lost script replacement, urine drug screening as requested.
- Escalate early. If the case is complex â dependency history, dose escalation, multiple prescribers â refer to a specialist addiction physician or drug and alcohol service before continuing.
- Document your reasoning. Notes should explain why an S8 was clinically appropriate, what alternatives were considered, and what monitoring is planned.
What counts as "drug-dependent" for permit purposes?
Definitions vary by jurisdiction. Common indicators include: prior treatment for substance dependence, use of S8 medicines for a purpose other than initially prescribed, use of multiple prescribers ("doctor shopping"), and any pattern indicating loss of control over use. Check the specific definition in your state's legislation â it determines when permit requirements are triggered.
What about medicinal cannabis?
Medicinal cannabis is a Schedule 8 medicine (except Schedule 4 CBD-only products meeting certain criteria). TGA Special Access Scheme (SAS) or Authorised Prescriber approval is required at the Commonwealth level, plus any state-based S8 authorisation. See our medicinal cannabis prescribing guide for detailed pathway.
What about buprenorphine / methadone (opioid dependency treatment)?
Opioid dependency treatment (OTP / MATOD / OMT â names vary by state) requires separate prescriber accreditation on top of general S8 authority. Programs are state-run: NSW OTP, VIC Pharmacotherapy, QLD Opioid Dependence Treatment Program, WA CPOP, SA Drug and Alcohol Services SA, etc. Contact your state health department for the current pathway.
