Is Quetiapine legal in Australia?

Also known as: seroquel

Legal status

Prescription only medicine under the Poisons Standard; no Commonwealth criminal drug status. F2026L01327 names quetiapine in Schedule 4, «QUETIAPINE.». Appendix K lists it among medicines carrying a sedation warning. It is not listed in Schedule 1 or Schedule 2 of the Criminal Code Regulations 2019 (Compilation No. 6). Nearest listed drug: benzylpiperazine (Schedule 1 item 27, Schedule 2 item 23), the only listed drug that shares quetiapine's piperazine ring. Limb (a) of s301.9(1) does not reach it because its molecular formula differs from benzylpiperazine's, so it is no isomer, and it is not an alkaloid of a listed drug; limb (c) does not, because quetiapine carries a three-ring dibenzothiazepine where benzylpiperazine carries a benzyl group, which adds rings beyond the replacement of up to 2 rings in (c)(i), and a hydroxyethoxyethyl chain that s301.9(2) does not specify; and on the method stated next limb (d) does not, because adding rings puts it outside s301.9 on that method. The method used for every row is a reading, not a rule the Act states: a modification that limb (a) or limb (c) plainly describes is treated as making a drug analogue; one contestable modification (a swap within one paragraph of s301.9(2), or a core ring replaced), a single limb (d) change from the listed drug, or an express exclusion or different listing in the Regulations is treated as making the exposure conditional; anything more, including adding or removing a ring, is treated as outside s301.9. Because s301.9(1)(c) allows a modification «obtained in one or more of the following ways», the tier this gives can depend on how a change is described, and nothing read settles which description governs. No court decision applying s301.9 to quetiapine was read, so this is a reading of the text. Nor is it named in Schedule 4 of the Customs (Prohibited Imports) Regulations 1956 as in force on 2 October 2026. The Poisons Standard read is the Poisons Standard October 2026 (Federal Register of Legislation F2026L01327, made 28 September 2026, registered 30 September 2026, in force from 1 October 2026 under its s2, replacing the June 2026 issue; no later issue was registered when it was read). This cell states Commonwealth law only. The Poisons Standard has effect through adoption by each state and territory: its Reader's guide, which s5(1) of the instrument says is not part of it, states «The scheduling of poisons is implemented through relevant State and Territory legislation.» Most personal possession and use offences are state and territory law, which differs by jurisdiction, and Criminal Code s300.4 keeps those laws running concurrently with Part 9.1. Read as in force on 2 October 2026 against F2026L01327, the Criminal Code Act 1995 at Compilation No. 174 (compilation date 30 June 2026, C2026C00243), the Criminal Code Regulations 2019 at Compilation No. 6 (compilation date 13 December 2025, F2025C01260) and the Customs (Prohibited Imports) Regulations 1956 at Compilation No. 147 (compilation date 13 July 2026, F2026C00751). The Criminal Code Regulations schedules are made by the Governor-General and the Poisons Standard by a delegate of the Secretary under Therapeutic Goods Act 1989 s52D, so a later instrument can change any of this, and this reading does not rule out a later amendment.

Consequences if caught

Capital exposure: none. The highest penalty anywhere in Part 9.1 of the Criminal Code is imprisonment for life, and Death Penalty Abolition Act 1973 s6 provides «The punishment of death must not be imposed as the penalty for any offence referred to in subsection 3(2) or (3).» No Commonwealth criminal offence reaches possession, sale, supply, manufacture or use of quetiapine: it is not a controlled or border controlled drug, and it is not a prohibited import under Schedule 4 of the Customs (Prohibited Imports) Regulations 1956 (Compilation No. 147), so the Customs Act 1901 s233 offence for prohibited imports does not reach its import. Supply is controlled by state and territory poisons law applying its Poisons Standard schedule. Part 9.2 of the Criminal Code is the residual import offence: s320.2 punishes importing a psychoactive substance by 5 years or 300 penalty units, or both, and s320.3 importing a substance presented as a serious drug alternative by 2 years or 120 penalty units, or both; s320.2(2) excludes listed or registered therapeutic goods, goods represented for therapeutic use other than as a serious drug alternative, industrial chemicals, a plant or fungus or an extract from one, any serious drug or precursor, and any prohibited import within the meaning of the Customs Act. There is no Commonwealth offence of using or consuming a drug; use is left to state and territory law. A penalty unit is $364 for an offence committed on or after 1 July 2026 under the Crimes (Amount of a Penalty Unit) Instrument 2026 (F2026N00424), made under Crimes Act 1914 s4AA, so 400 penalty units is $145,600, 2,000 is $728,000 and 7,500 is $2,730,000; «or both» in each penalty means the prison term and the fine are available alternatively or together.

If prescribed or medical

Quetiapine is a Schedule 4 prescription only medicine. The Reader's guide, which is not part of the instrument, describes Schedule 4 as «Substances, the use or supply of which should be by or on the order of persons permitted by State or Territory legislation to prescribe and should be available from a pharmacist on prescription.»

Documentation

Its import is not prohibited by the Customs (Prohibited Imports) Regulations; the personal import limits are those of the rule in Therapeutic Goods Regulations 1990 Schedule 5 item 1 (Compilation No. 130), which covers «therapeutic goods that are imported for therapeutic use in the treatment of the importer or the importer’s immediate family», limited to «not more than 3 months’ supply at the maximum dose recommended by the manufacturer» in one importation, no more than 15 months’ supply in 12 months, and, because it is a Schedule 4 good, a written authority from a medical practitioner, or an overseas medical practitioner where a passenger carries it. The ABF traveller guidance asks travellers to carry «a letter or copy of your prescription (written in English)» and declare the medicine. The Therapeutic Goods Administration and Office of Drug Control traveller pages (tga.gov.au, odc.gov.au) did not respond from this network on 2 October 2026 (curl timeout after 60 seconds, twice, and a second fetcher timed out), so nothing in this cell rests on them.

Drug laws and enforcement change and vary within a country. This is not legal advice. Always confirm with Australia’s embassy or official drug authority before traveling; penalties can be severe, including imprisonment.
