Cannabis Laws & Legality in Australia — Complete State-by-State Guide
Australia has no single cannabis law — it has nine, overlapping and often contradictory. What's legal in Canberra can be a criminal offence twenty minutes away in Queanbeyan, NSW. This guide breaks down the actual legislation, real possession thresholds, and current penalties in every state and territory, plus the federal picture, the driving law trap that catches even prescription holders, and where reform genuinely stands in 2026.
Cannabis Under Australian Federal Law
Cannabis is classified as a Schedule 9 prohibited substance under the national Poisons Standard. At the federal level, this means recreational manufacture, possession, use, and supply are prohibited across the entire country — full stop. There is no federal carve-out for recreational use anywhere in Australia, including the ACT; the ACT's decriminalisation is a state-level (territory-level) legal change that reduces enforcement risk locally but does not alter cannabis's federal prohibited status.
The one major federal exception is medical use. On 24 February 2016, the Narcotic Drugs Amendment Act 2016 legalised the cultivation and production of cannabis for medicinal and scientific purposes at the federal level, and medical cannabis has been accessible nationwide since via the Therapeutic Goods Administration's Special Access Scheme and Authorised Prescriber pathways — see our dedicated Beginner's Guide to Medical Cannabis in Australia for the full patient process.
The 2023 Legalising Cannabis Bill — What Actually Happened
In August 2023, Australian Greens Senator David Shoebridge introduced the Legalising Cannabis Bill 2023 — the first bill in Australian federal parliamentary history to propose legalising recreational cannabis nationwide. It would have allowed adults 18+ to possess up to 50g, grow up to 6 plants per household, and share homegrown cannabis, while creating a new statutory body (the Cannabis Australia National Agency) to regulate strains, sales, and cannabis cafés.
The Senate Legal and Constitutional Affairs Committee reviewed the bill and, on 31 May 2024, recommended against passing it. Despite that, Senator Shoebridge brought it to a full Senate vote. On 27 November 2024, the bill was defeated 13 votes to 24, with Labor and the Coalition voting together against it. All 11 Greens senators plus two independents voted in favour. Federal Labor Senator Don Farrell argued during debate that recreational cannabis law is a matter for the states, not the Commonwealth.
This was a genuinely historic vote — the first time federal parliament had ever voted on the question — but it was a clear defeat, not a bill still "under consideration." Any near-term path to national legalisation would need to come from state and territory governments acting individually, as the ACT already has, rather than from Canberra.
Cannabis Law in Every Australian State and Territory
This is where Australian cannabis law actually gets complicated. Below is the current legal position, possession thresholds, and penalty structure for all eight jurisdictions.
🇦🇺 Australian Capital Territory (ACT)
Personal Use LegalThe ACT is the only Australian jurisdiction that has genuinely decriminalised — effectively legalised at the territory level — personal cannabis use. Under the Drugs of Dependence (Personal Cannabis Use) Amendment Act 2019, in force since 31 January 2020, adults 18+ may:
• Possess up to 50g of dried cannabis (or up to 150g fresh/wet cannabis)
• Cultivate up to 2 plants per person, capped at 4 plants per household
Still illegal: selling, supplying, or gifting cannabis to anyone (even without payment), consuming in public, and possessing above the stated limits. There is no legal retail market — cannabis must be grown personally. Because federal law still prohibits cannabis nationwide, carrying it across the ACT border into NSW remains an offence under NSW law the moment you cross.
🐨 New South Wales (NSW)
Illegal — Diversion AvailablePossession is a criminal offence under section 21 of the Drug Misuse and Trafficking Act 1985, carrying a maximum penalty of 2 years imprisonment and/or a fine up to $2,200. In practice, police have discretion under the Cannabis Cautioning Scheme to issue a caution instead of charging for possession of up to 15g — available a maximum of two times per person. Alternatively, police may issue an on-the-spot $400 penalty notice under section 333 of the Criminal Procedure Act 1986. Cultivation remains illegal at any scale.
🏙️ Victoria
Illegal — Warning for First OffenceRecreational use and possession remain illegal. First-time offenders found with 50g or less typically receive an informal warning and referral to drug counselling rather than prosecution, at police discretion. Possession of 250g or 10 plants crosses into a trafficking-level offence with substantially harsher penalties. Victoria has separately introduced court discretion around drug-driving penalties for medicinal cannabis patients — see the driving section below.
☀️ Queensland
Illegal — Strict EnforcementCannabis is illegal to grow, use, or possess under Queensland's drug legislation. A Police Diversion Program exists for possession of up to 50g, requiring attendance at a drug assessment and education session in place of prosecution — but this is discretionary and unavailable for repeat offenders. Supply, production, and trafficking carry maximum penalties of up to 20 years imprisonment. Queensland's government has explicitly and repeatedly ruled out following other states toward reform, maintaining one of the strictest zero-tolerance stances in the country as of 2026, including on drug-driving.
🍷 South Australia
Civil Expiation SchemeSouth Australia runs the country's longest-standing cannabis decriminalisation model, in place since 1986. Possession of up to 100g of dried cannabis, one non-hydroponic outdoor plant, or a small quantity of resin is treated as a "simple cannabis offence" — police issue an on-the-spot Cannabis Expiation Notice (CEN), a fine that resolves the matter without a criminal conviction, provided no aggravating factors apply. Amounts above this threshold, hydroponic cultivation, or repeat non-payment of expiation fines can still result in prosecution. Trafficking carries severe penalties, including fines up to $1 million and sentences from 15 years to life.
🏖️ Western Australia
Cannabis Intervention RequirementWA operates the Cannabis Intervention Requirement (CIR) scheme: possession of up to 10g can result in mandatory drug education instead of criminal charges. Possession above 10g and up to 100g attracts a fine and up to 2 years' imprisonment as a maximum penalty, with actual sentencing varying by circumstance. Repeated offences or amounts beyond these thresholds are prosecuted more seriously, and cultivation for recreational purposes remains illegal.
🍎 Tasmania
Illegal — Caution SystemTasmania Police may issue up to three cautions for possession of under 50g, with escalating requirements for counselling or education attached to later cautions. Amounts above this threshold, or offending beyond the third caution, lead to prosecution. Tasmania is notable for offering the most patient-friendly medicinal cannabis driving provisions in the country — see below.
🌴 Northern Territory
Partial DecriminalisationThe NT has operated a form of decriminalisation since 1996: adults found with up to 50g in a private residence can be dealt with via a fine rather than criminal prosecution. Critically, this protection does not extend to public places — possession of even a small quantity in public can still lead to imprisonment. Cultivating five or fewer plants risks imprisonment; cultivating more than 20 plants carries a maximum lifetime sentence, treating larger home grows the same as commercial trafficking.
Possession Thresholds at a Glance
| Jurisdiction | Legal Status | Threshold Before Charges | Home Cultivation |
|---|---|---|---|
| ACT | Legal (personal use) | 50g dried / 150g fresh | 2 plants/person, 4/household |
| NSW | Illegal | Caution possible ≤15g (max 2x) | Illegal |
| Victoria | Illegal | Warning possible ≤50g (first offence) | Illegal |
| Queensland | Illegal | Diversion possible ≤50g | Illegal |
| South Australia | Civil expiation | Fine (no conviction) ≤100g / 1 plant | 1 plant via expiation (outdoor only) |
| Western Australia | Illegal (diversion) | Education ≤10g; fine+jail 10–100g | Illegal |
| Tasmania | Illegal | Up to 3 cautions ≤50g | Illegal |
| Northern Territory | Partial decrim | Fine ≤50g (private residence only) | ≤5 plants risks jail; 20+ = life |
Figures are current as researched but subject to change — always confirm with the relevant state or territory police or health department before relying on these thresholds.
Interstate Travel: Legal Here Doesn't Mean Legal There
There is no "grandfathering" or transport exemption for cannabis purchased or grown legally in one jurisdiction. If you are travelling between states — even just driving from Canberra to Sydney for the day — cannabis that was legal in your bag five minutes ago can expose you to prosecution the moment you cross the border.
Driving Laws — Presence, Not Impairment
Australian drug-driving law is structured differently to alcohol law in a way that surprises most people, including many medical cannabis patients: roadside testing detects the mere presence of THC, not impairment. THC can remain detectable for hours or days after any impairment has worn off.
• NSW — 2026 reform allows registered medicinal patients under a lab-tested threshold to avoid automatic penalty (three-strike warning system)
• Victoria — courts have discretion not to automatically cancel a licence for prescription holders who were not impaired
• Tasmania — uniquely permits driving with THC present for unimpaired prescription holders, though the Department of Health still advises against it
• Queensland, WA, SA, NT, ACT — strict zero-tolerance regardless of prescription status
This applies to any detectable THC — recreational or prescribed. For the full breakdown of state-by-state driving rules, see our Beginner's Guide to Medical Cannabis in Australia, which covers this in more detail for patients specifically.
Medical Cannabis — Legal Nationwide
Unlike every recreational rule above, medical cannabis access is uniform across all eight states and territories. Since the Narcotic Drugs Amendment Act 2016, patients with a valid prescription can legally access medical cannabis products anywhere in Australia through the TGA's Special Access Scheme or Authorised Prescriber pathway — the state you live in doesn't change your legal access to prescribed treatment, even though it dramatically changes your recreational legal exposure. Over 500,000 prescriptions had been written nationally by 2025.

Reform Timeline
Public opinion has continued shifting — polling has shown majority support for decriminalisation of small-quantity possession nationally — but as of 2026, that hasn't translated into further legislative change beyond the ACT's 2020 reform and incremental state-based driving-law adjustments.
