How Much Is Ketamine in Australia? A Complete Cost Guide
The cost of ketamine in Australia varies dramatically depending on whether you are accessing it through legitimate medical channels or the illicit market. Prescription ketamine for treatment-resistant depression is available through the PBS at a subsidised rate, while generic ketamine used off-label remains far cheaper per dose. In contrast, non-prescribed ketamine circulating in the community commands prices that reflect its illegal status. Consequently, understanding these distinct cost structures is essential for anyone seeking clarity on ketamine pricing in Australia.
The PBS Subsidy: Esketamine Nasal Spray
The most significant development in Australian ketamine pricing is the Pharmaceutical Benefits Scheme (PBS) listing of esketamine nasal spray (Spravato) for treatment-resistant depression. This listing took effect on 1 May 2025 and has transformed the cost structure for patients.
Under the PBS, the general patient co-payment for esketamine is capped at $25.00 per prescription as of 1 January 2026 . For Commonwealth concession card holders, the co-payment remains frozen at $7.70 until 2030 . This represents a dramatic reduction from the pre-PBS cost, which ranged from $500 to $900 per dose .
However, the PBS subsidy only covers the medication itself. The administration and supervision fees are not covered by Medicare or typically by private health insurance . These out-of-pocket costs can be substantial. For example, Daintree Psychiatry charges $320.00 per 60-minute esketamine administration session, which includes medical supervision and monitoring, with no rebate available . Epworth Clinic charges a $340 procedure fee per session . Professor Colleen Loo notes that treatment sessions cost patients around $300-$400 per session, and this aspect is not covered by the PBS .
The total out-of-pocket cost for a full course of esketamine treatment therefore extends well beyond the subsidised medication price. A typical initial course involves 12 treatment sessions over 8 weeks .
Generic Ketamine: The Low-Cost Alternative
Generic racemic ketamine presents a starkly different cost profile. The medication itself costs only $5 to $20 per dose . This makes generic ketamine far cheaper than esketamine on a per-dose basis.
However, generic ketamine is not TGA-approved for treatment-resistant depression and must be used off-label . This has significant financial implications. Because there is no Medicare Benefits Schedule (MBS) code covering the staffing costs for ketamine treatment administration, the service delivery costs are not reimbursed . These costs, estimated at around $3,600 for an 8-week course, comprise the bulk of total costs for generic ketamine treatment .
Professor Colleen Loo has highlighted this disparity: “There’s a huge difference in costs, but both have been shown to be really effective. But only one is subsidized by the government and formally approved, while the other more affordable option is used off-label” .
Non-Prescribed Ketamine: The Illicit Market
For non-prescribed ketamine, pricing data comes from law enforcement seizures and drug monitoring reports. The Australian Criminal Intelligence Commission’s National Wastewater Drug Monitoring Program provides one of the most reliable indicators of illicit market pricing.
According to the 2025 ACT report, the median price of non-prescribed ketamine per gram in Canberra is tracked as part of ongoing monitoring . While the specific dollar figure is not detailed in the available excerpt, this data source represents the authoritative measure for illicit ketamine pricing in Australia.
Law enforcement seizures provide additional pricing benchmarks. In April 2026, a woman was charged in Cranbourne East after police seized approximately 1kg of ketamine with an estimated street value of $40,000 . This equates to approximately $40 per gram. In a separate case, a Darwin man was charged over the importation of 4kg of ketamine with an estimated street value of $800,000, which equates to approximately $200 per gram . The discrepancy between these figures may reflect differences in purity, location, or the stage of the supply chain at which the valuation was made.
Factors Influencing Ketamine Prices
Several factors explain the wide variation in ketamine pricing across Australia.
Legitimacy of access: PBS-subsidised esketamine is the most affordable option for patients who qualify for treatment-resistant depression, but eligibility is strictly limited to those who have failed multiple other treatments. Generic ketamine is cheaper per dose but lacks government subsidy for the administration costs. Illicit ketamine carries the highest legal risk and no quality assurance.
Geographic location: Prices may vary between capital cities and regional areas, reflecting differences in supply chains and demand.
Quantity purchased: Bulk purchases, such as the 1kg seizure valued at $40,000, typically command lower prices per gram than smaller retail quantities.
Purity and quality: Illicit ketamine may be adulterated with other substances, affecting both its effects and its value.
The Rising Trend of Recreational Use
Understanding ketamine pricing requires acknowledging the broader context of increasing recreational use. A nationwide wastewater study led by Adelaide University found that ketamine mass loads increased across Australia from 2022 to 2025, with the average population-normalised mass load rising from approximately 2.7 mg/day/1000 people in December 2020 to 5.8 mg/day/1000 people in April 2025 . The study observed substantially elevated excretion on weekends, suggesting an increase in recreational or non-medical use .
The study also found that ketamine use was highest in the most advantaged socioeconomic quartile, with a population-weighted average of 6 mg/day/1000 people compared to 3-4 mg/day/1000 people in other quartiles . National data supports this trend, with the proportion of Australians who have ever used ketamine rising from 1.9% in 2016 to 4.3% in 2023 .
Summary
The cost of ketamine in Australia depends entirely on the access pathway. PBS-subsidised esketamine costs $25.00 per script for general patients and $7.70 for concession card holders, but administration fees of $300-$400 per session are not covered. Generic ketamine costs only $5-$20 per dose, but the $3,600 service delivery cost for an 8-week course is not reimbursed without an MBS code. Non-prescribed ketamine on the illicit market carries prices ranging from approximately $40 to $200 per gram based on law enforcement valuations, alongside significant legal risks and no quality assurance. The most affordable option for eligible patients is PBS-subsidised esketamine, though the “hidden” administration costs remain a barrier for many Australians seeking treatment.
