DMT in Australia: Botanical Reality, Clinical Research, and Legal Status

The story of DMT in Australia is one of striking contrasts. On one hand, the compound occurs naturally in the country’s iconic wattle trees. On the other, it remains one of the most strictly prohibited substances under Australian law. Consequently, understanding DMT in this country requires examining both the botanical science and the legal framework that governs it. This guide explores Australia’s unique relationship with dimethyltryptamine.

Australia’s Botanical Connection: DMT in Native Acacia

Australia’s native flora holds a surprising secret. The Acacia genus, commonly known as wattle, contains N,N-dimethyltryptamine (DMT) in various species. Western Australia is a global centre of diversity for Acacia, with 894 species naturally found across the state. However, not every wattle tree contains the compound. Just as not all mushrooms are magic, the presence of DMT is not uniform across species.

Scientific research has made significant progress in mapping which species contain DMT. A 2024 study analysed 104 plant samples representing 79 Acacia species. The findings determined 51 DMT-containing species, 41 of which were previously unknown to contain the psychedelic. This research dramatically expanded the known range of DMT-producing Acacia in Australia.

Further chemical analysis has unequivocally demonstrated the presence of tryptamines (including DMT), β-carbolines, histamines, and phenethylamines in Australian Acacia species. Interestingly, the Australian species appear more chemically similar to Vachellia and Senegalia from the Americas than to their African counterparts.

A key distinction from the more well-known ayahuasca brew is that Australian Acacia species may contain both tryptamines and β-carbolines within a single specimen. These are the two chemical families required for ayahuasca’s synergistic effects, which traditionally requires two different plant species.

However, extraction from these plants faces practical obstacles. Wattle contains only 0.5–1.5% DMT, meaning a massive amount of plant material is required to yield even a small quantity. Furthermore, ringbarking trees kills them, and destroying native flora is illegal in itself.

Clinical Research: The Scientific Frontier

Despite the legal prohibitions, Australian researchers are at the forefront of investigating DMT’s potential therapeutic benefits. This research focuses on developing standardised, pharmaceutical-grade formulations rather than using botanical products.

A major clinical trial is being led by Swinburne University of Technology, which received $1,977,354.90 from the Medical Research Future Fund. The project, titled “Dimethyltryptamine (DMT)-Assisted Psychological Therapy for Treatment-Resistant Major Depression, Alcohol Use Disorder, and Dual Diagnosis,” runs from January 2022 to August 2027. The research aims to conduct a clinical trial using DMT for adults with alcohol use disorder (AUD) and/or major depressive disorder (MDD).

Dr Daniel Perkins is a Senior Research Fellow and Head of the Psychedelics Research and Therapeutics Unit at the University of Melbourne. He is also CEO of Neurala Biosciences, a University of Melbourne spin-out company developing novel neuromedicines for mental health and addictive disorders. Dr Perkins holds dual PhDs, including one focused on the potential therapeutic use of DMT–harmala alkaloid psychedelic preparations.

A separate open-label exploratory study explored the safety, tolerability, and psychedelic effects of three Acacia-based formulations in nine healthy volunteers with prior ayahuasca experience. The formulations were derived from two Acacia species, containing 1mg/kg DMT and 4mg/kg of harmalas. The results indicated that all formulations had a good safety profile, with no serious adverse events reported. The subjective experience was generally rated similar to ayahuasca, and four-week follow-up measures showed little difference between formulations. The researchers concluded that DMT formulations derived from Acacia species represent a feasible alternative to traditional ayahuasca for future clinical trials.

The Legal Framework: Schedule 9 Prohibition

Despite its natural occurrence in Australian flora and ongoing clinical research, DMT remains a Schedule 9 prohibited substance under the Poisons Standard. This classification places it in the highest category of restriction, reserved for substances with no accepted medical use and a high potential for abuse.

The possession, use, manufacture, supply, importation, or exportation of ayahuasca—more specifically DMT—is illegal across all States and Territories in Australia. The legal treatment is consistent across the country.

Penalties escalate dramatically based on quantity. In New South Wales, the Drug Misuse and Trafficking Act 1985 classifies DMT as a prohibited drug:

• Possession: Maximum penalty of two years imprisonment and/or a $2,200 fine
• Supply (small quantity, 0.8 grams): $5,500 fine and/or 2 years imprisonment (Local Court), or $220,000 fine and/or 15 years imprisonment (District Court)
• Supply (commercial quantity, 0.5 kg): $385,000 fine and/or 20 years imprisonment
• Supply (large commercial quantity, 2 kg): $550,000 fine and/or life imprisonment

Similar prohibitions apply across other Australian jurisdictions. Victoria criminalises DMT under the Drugs, Poisons and Controlled Substances Act 1981. Queensland enforces its prohibitions through the Drugs Misuse Act 1986. Tasmania, South Australia, the Northern Territory, and the ACT all have similar legislation.

Notably, the Australian Capital Territory (ACT) has decriminalised the possession of small amounts of some illicit drugs. However, this has not extended to DMT.

Enforcement and Real Cases

Law enforcement actively targets DMT distribution. In 2026, Andreas Panas, a 39-year-old South Australian man with a prior conviction for a meth lab explosion, pleaded guilty to importing a border-controlled drug after ordering DMT online. His first order was placed on July 18, 2024, for $353. Further purchases followed in November 2024 for about $450 and again in July 2025 for $483. The final consignment intercepted by the Australian Border Force contained 19.2 grams of pure DMT. He used his own name, home address, and bank account to place the orders. Defence counsel stated Panas imported the drug for “spiritual purposes,” claiming he used DMT to help manage bipolar disorder and depression after struggling to access prescribed medication. He is due to be sentenced on the DMT offences.

Patterns of Use in Australia

Data from the National Drug and Alcohol Research Centre (NDARC) provides insight into DMT use patterns in Australia. In 2024, 10% of participants reported recent DMT use, stable relative to 2023 (13%). Use has remained consistently below 20% of the sample over the reporting period.

The frequency of use is infrequent and stable, with a median of two days of use reported by participants in 2024. Among participants who had recently consumed DMT, the most common route of administration was smoking (92%). The median amount used in a “typical” session was 10 mgs.

The Alcohol and Drug Foundation confirms that DMT is most commonly smoked in Australia, with effects commencing almost straight away and finishing after around 30 minutes. Effects may include a “rush,” changes in mood, increased sensitivity to bodily sensations, increased heart rate and blood pressure, anxiety and confusion, intense visual hallucinations, and dissociation.

Harm Reduction and Safety

For those who might encounter DMT, understanding the risks is crucial. The Alcohol and Drug Foundation warns that if someone takes a large amount, the negative effects of DMT are more likely. These can include vomiting, inability to move, intense anxiety and confusion, overwhelming fear and paranoia, and even psychosis.

DanceWize, a peer-based harm reduction organisation, provides guidance for safer use. Key recommendations include using around people you trust and somewhere you feel safe, having a sober or experienced trip sitter present, and sitting or lying down for the experience in a place with low stimuli. The desired vaporisation temperature is between 60–80 degrees Celsius, as it is easy to burn DMT. A recreational dose (vaporised) is approximately 5–10mg (light) to 35mg (heavy).

Dangerous combinations should be avoided. Tramadol may cause seizures when combined with DMT. Cannabis increases the risk of anxiety, paranoia, panic, and psychosis.

Conclusion

DMT in Australia is a story of contrasts. It is a naturally occurring compound in the nation’s iconic wattle trees, yet it is classified as one of the most strictly prohibited substances. While this legal status blocks public access, it has not stopped world-class clinical research from investigating its therapeutic potential for severe, treatment-resistant mental health conditions.

For now, DMT remains a substance of scientific intrigue and legal restriction. The clinical trials underway at Swinburne University and the University of Melbourne represent the only legitimate pathways for Australians to engage with this compound. The future of DMT in Australian medicine is still being written, but the research is progressing within the boundaries of the law.
