These aren't abstract figures—they represent real harm
A nation's hidden consumption, measured not in confessions but in the chemistry of its waterways, has revealed a decade-long doubling of methamphetamine use across Australia — placing it second only to the United States in global rankings. The Australian Criminal Intelligence Commission's wastewater analysis of 64 treatment plants offers a rare and unflinching mirror to a society where stimulant demand has quietly surged to record levels, touching regional towns and capital cities alike. What the data describes is not merely a law enforcement challenge but a sustained human condition — one shaped by transnational supply chains, geographic isolation, and the enduring pull of substances that promise relief from lives under pressure.
- Australia's methamphetamine consumption has nearly doubled in a decade to 15,971 kilograms annually — the highest figure since wastewater monitoring began, and enough to rank the country second in the world.
- Cocaine, heroin, and MDMA have simultaneously hit record highs, with the combined illicit drug market swelling to $14.3 billion — a figure that signals not a crisis at the margins but one embedded in the mainstream.
- Regional communities bear a disproportionate burden, with Tasmania, the Northern Territory, and the ACT recording the steepest rises in meth use, while the Northern Territory saw heroin consumption spike by 50 percent in a single year.
- Transnational criminal organizations are adapting faster than enforcement can respond, with new synthetic opioids now entering the Australian market and global production of cocaine and meth at record levels.
- Authorities are calling for sustained national coordination and evolving tools, framing wastewater surveillance as an essential lens — but the gap between data clarity and policy response remains the central unresolved tension.
Australia's methamphetamine consumption has nearly doubled over the past decade, and new findings from the Australian Criminal Intelligence Commission make the scale impossible to ignore. Drawing on wastewater analysis from 64 treatment plants monitored between August 2024 and 2025, the commission found that annual crystal meth consumption climbed from 8,405 kilograms to 15,971 kilograms — the highest level recorded since the program began in 2016. By international comparison, Australia now ranks second globally in methamphetamine use, behind only the United States.
The crisis extends well beyond a single substance. Over the same period, combined consumption of meth, cocaine, MDMA, and heroin rose 21 percent, with the total illicit drug market reaching $14.3 billion in value. Methamphetamine alone accounts for 77 percent of that spending. Cocaine and heroin also hit record highs, with heroin surging 23 percent nationally and MDMA jumping 49 percent in New South Wales alone.
Chief executive Heather Cook described the findings as evidence of persistent, elevated demand across all jurisdictions — not abstract numbers, but harms unfolding in hospitals, homes, and communities. She also flagged the emergence of new synthetic opioids entering the Australian market, a development that adds urgency to an already strained public health landscape.
Geography shapes the crisis in distinct ways. Regional areas show higher rates of meth, cannabis, and oxycodone use, while cocaine and heroin concentrate in cities. Tasmania recorded the steepest annual rise in meth consumption at 38 percent, followed by the Northern Territory at 36 percent. The Northern Territory also saw heroin use spike by 50 percent year-over-year — a figure that speaks to acute vulnerability in already under-resourced communities.
One note of complexity: cannabis use, long Australia's most common illicit drug, actually declined over the period. But the broader trajectory is unmistakable. Cook called for sustained, coordinated national responses, arguing that the challenge demands constant vigilance and strong cross-jurisdictional collaboration. Wastewater monitoring has become an indispensable tool — offering a more honest account of consumption than arrest records or treatment data alone — but the distance between knowing and responding remains the defining challenge.
Australia's appetite for methamphetamine has nearly doubled over the past decade, reaching levels that have alarmed public health officials and law enforcement. The Australian Criminal Intelligence Commission released findings this week based on wastewater analysis from 64 treatment plants across the country between August 2024 and 2025, revealing consumption patterns that paint a stark picture of drug use across the nation.
The numbers are striking. Crystal meth consumption climbed from 8,405 kilograms to 15,971 kilograms annually—the highest level recorded since the monitoring program began in 2016. Australia now ranks second globally in methamphetamine consumption, trailing only the United States, according to international wastewater testing standards overseen by the Sewage Core Group Europe, which coordinates data from 34 nations. Cocaine and ketamine have similarly reached record highs, while heroin consumption hit new peaks in major cities.
The scale extends beyond methamphetamine alone. In the year to August 2025, combined consumption of meth, cocaine, MDMA, and heroin surged by 21 percent compared to the previous year. Methamphetamine alone jumped 23 percent, heroin rose 23 percent, and cocaine climbed 20 percent. The financial dimension is equally sobering: the total market value of these four drugs ballooned from $11.5 billion to $14.3 billion, with methamphetamine accounting for 77 percent of all spending on major illicit drugs.
Heather Cook, the commission's chief executive, framed the findings as evidence of "persistent, elevated demand for major drugs across jurisdictions." She emphasized that these are not abstract statistics but concrete harms unfolding in hospitals, homes, and communities. The data also signals the arrival of new synthetic opioids entering the Australian market—a development that compounds existing concerns about supply and addiction.
Geographic patterns reveal important variations. Regional areas consume methamphetamine, cannabis, and oxycodone at higher rates than capital cities, while cocaine, heroin, and ketamine use concentrates in urban centers. Sydney leads in ketamine consumption. Tasmania recorded the steepest annual increase in meth use at 38 percent, followed by the Northern Territory at 36 percent and the Australian Capital Territory at 30 percent. The Northern Territory also saw heroin use spike by 50 percent year-over-year, while New South Wales experienced a 49 percent jump in MDMA consumption.
Cook characterized the situation as a reminder that Australia remains a lucrative target for transnational criminal organizations. Global cocaine and methamphetamine production has reached record levels, particularly in the Americas and Southeast Asia—the latter being the primary source of Australia's heroin supply. Criminal groups operating across borders have proven both persistent and innovative in maintaining supply chains despite enforcement efforts.
One counterpoint emerged in the data: cannabis consumption, long Australia's most widely used illicit drug, actually declined nationally between 2024 and 2025. Nicotine use ticked upward by 4 percent, while alcohol consumption increased in regional areas but fell in cities.
Cook called for "sustained, coordinated national responses," emphasizing that the challenge demands "constant vigilance, evolving tools and strong collaboration across all jurisdictions." The wastewater data has become a crucial tool for understanding drug consumption patterns in real time, offering a more complete picture than arrest records or treatment admissions alone. What emerges is a portrait of a nation grappling with stimulant use at unprecedented levels, with particular vulnerability in regional communities and growing sophistication among the criminal networks supplying the market.

The data reinforces the critical need for sustained, coordinated national responses. These aren't abstract figures—they represent real harm and real consequences playing out in hospitals, homes and communities across the country.— Heather Cook, chief executive of the Australian Criminal Intelligence Commission
Our intelligence continues to show that serious and organised crime groups are not only persistent but highly innovative. The scale of the markets shows just how determined these groups are to maintain supply.— Heather Cook
The Hearth Conversation Another angle on the story
Why does wastewater testing matter more than, say, counting arrests or hospital admissions?
Because it captures the full picture—not just the people caught or sick enough to seek help. It measures what's actually flowing through our pipes, which is what people are actually consuming, regardless of whether they've been arrested or admitted to hospital.
So Australia being second only to the US in meth consumption—does that surprise you?
It's sobering. We're a smaller population, so per capita we're consuming at extraordinary rates. The US has scale; we have intensity. That suggests either very efficient supply chains or very deep demand, or both.
The regional areas using more meth than cities—why would that be?
Partly isolation. In cities, there's more competition between drugs, more treatment access, more visibility. In regional areas, meth fills a void. It's cheap, it lasts, and there's less infrastructure to interrupt the cycle.
Methamphetamine is 77 percent of the illicit drug market value. That's enormous.
It's the profit engine. Cocaine and heroin are expensive per dose; meth is cheaper to produce and moves in volume. Criminal groups have optimized around it. That's why they keep pushing supply—the margins are there.
What does "emerging synthetic opioids" mean in practical terms?
It means fentanyl-type substances are starting to appear. They're more potent, harder to dose, and deadlier in overdose. It's the next wave, and the system isn't ready for it yet.
Can this trend reverse?
Not without sustained effort. You need supply disruption, treatment capacity, and demand reduction all working together. Right now, the data suggests none of those are winning.
