Harm Reduction Hub

Peer-Led National Harm Reduction Information
Peer-Led Governance © Ed Broadbent, March 2026

Harm reduction follows a specific flow. In both directions.

Five dimensions, a pentagon, each feeding the next in a cyclical flow. Signals move inward: from the individual, through community, into health systems, generating research evidence, informing government. And they flow outward: from the hub back to each entity through locked governance flows: alerts, advisories, data access, and policy intelligence, all calibrated by tier. The cycle is continuous. Each vertex feeds the next and receives from the hub.

Government's role is a reporting mechanism for harm reduction. Not a tool to attack community. The governance locks ensure that what flows out respects the same hierarchy as what flows in. Distribution follows community governance: RSS feeds, tiered APIs, and direct alerts carry information to the right audience at the right level.

"A common focus on preventing and minimizing drug-related harms, rather than pursuing other agendas, such as prosecuting drug laws."
Siefried et al., Frontiers in Public Health, 2025

Signal inward: Individual → Community → Health → Research → Government

1

Individual

The person who uses drugs is the first detector of supply changes. "People who use drugs have long demonstrated care for each other and play a vital role in alerting each other to concerns regarding drug supply."

Freestone, Broadbent et al., 2025
2

Community

AIVL as the national peak body, with state and territory member organisations (NUAA, Harm Reduction Victoria, PBHRWA, and others) as the federated network. Community isn't consulted. Community governs. "People with lived and living experience of drug use" hold structural authority. Information flows between organisations via RSS feeds and shared alert channels, ensuring every jurisdiction stays connected without surrendering sovereignty.

Siefried et al., Frontiers in Public Health, 2025
3

Health

AOD services, clinicians, and drug checking services form the clinical response layer. Co-located with community. CheQpoint peer-staffed within QuIHN needle/syringe programme. Health responds to community signal, not the other way around.

Puljević et al., Drug and Alcohol Review, 2025
4

Research

Evidence synthesis and pattern detection. The PRN co-design identified the need for a "national drug signal database and an anecdotal reporting system", giving people the opportunity to safely and anonymously report observations of new trends, harms or other concerns.

Siefried et al., Frontiers in Public Health, 2025
5

Government

Government receives harm reduction intelligence as a reporting mechanism: informed policy response, not enforcement. Justice has its own systems for other dimensions of mental health and drug policy. For harm reduction, the flow is specific: government is the recipient of community intelligence, not the originator.

Broadbent et al., Evidence Brief: Governance and Collaboration, 2023

What the Hub Is

A federated national platform for drug harm reduction. Connecting alerts, data, research, and community across jurisdictions under peer-led cyclical governance. AIVL as the national peak body and community voice. ADF as a family connection and ally. RSS feeds as the connective tissue between sector stakeholders. Mental health and suicide prevention as a natural crossover, not an afterthought.

What the Hub Is Not

A research centre. A surveillance system. A university product. An extension of any existing institutional infrastructure. A replacement for state systems. A justice tool.

Key Capabilities

What the Hub delivers, and why clear governance makes agile delivery possible.

International First

Peer-Led National Signal System

The first known peer-led national harm reduction information system globally. Lived experience doesn't advise the system. It governs the system. Community voice is structural, not consultative.

National + State

Peer-Led Reporting Infrastructure

New national and state-level peer-led reporting mechanisms. Facilitated reporting for DOHAC and other funding bodies. The hub produces the evidence funders need, governed by the community that generates it.

NPS Tracking

First Known Appearance Registry

First known appearance of novel psychoactive substances (NPS) tracked nationally. Multi-name, poly-drug, alias matching. When a new substance appears in Australia, the hub knows first, because the community knows first.

Governance = Speed

Clear Governance Enables Agile Delivery

The governance architecture is already planned. When governance is clear and locked, delivery is fast. No ambiguity about who decides, who accesses, who reports. The pentagon flow is the delivery architecture.

Differentiated Feeds

Different Feeds for Different Audiences

Not everyone sees the same data. AIVL sees peer intelligence. ADF sees family-relevant alerts. Forums and Discord get community signal. Government gets policy-level reporting. Health gets clinical data. Each feed calibrated to role and need.

Already Connected

Beyond AOD: Mental Health & Suicide Prevention

The crossover between drug harm reduction and mental health is already live, not theoretical. Ed has directly connected in Headspace on emerging harm reduction information. The same RSS infrastructure that distributes drug alerts can carry mental health context to AOD workers, and AOD signal intelligence to mental health services. Suicide prevention, dual diagnosis, and youth mental health are natural extensions of peer-led harm reduction intelligence, because the people experiencing drug-related harm are often the same people navigating mental health crises.

Sector First

AOD Communication Guidelines: The Mindframe Gap

Australia has Mindframe guidelines for responsible media reporting on suicide and mental health, developed by Everymind. No equivalent exists for alcohol and other drugs. The Hub's tiered alert system creates the operational infrastructure, but the sector also needs nationally agreed communication guidelines for AOD reporting: language standards, alert framing, reducing stigma in public drug warnings, and ensuring lived experience informs how drug information reaches communities. A co-authored guideline with Everymind/Mindframe for AOD would be a natural and necessary complement to the Hub's technical architecture.

RSS-First

RSS Feeds as Sector Connective Tissue

The Hub distributes intelligence via RSS feeds: machine-readable, subscribable, and interoperable. Any organisation, from a peer network to a PHN to a mental health service, can subscribe to filtered feeds calibrated to their role. This is the same infrastructure that expanded The Know's audience tenfold. RSS means the Hub doesn't need every stakeholder on the same platform. It meets them where they are.

Organisational Roles

Community Voice
AIVL
National peak body for people who use drugs. Lived experience at the centre. Peer-led governance, community voice, platform stewardship. State and territory member organisations form the federated network. The hub exists because the community it serves governs it.
Family Connection & Ally
ADF
Broader family and community engagement. An ally connecting the hub to families and communities affected by drug use. Not clinical lead, but essential bridge.
Funder & Integrator
Health (DOHAC)
National health infrastructure funding, clinical governance standards, and facilitated reporting recipient. Community governs; health funds and integrates.
Federation
State/Territory
Federated: retain sovereignty, gain interoperability
Contributor
Academia
Supported research tier; plugs into platform, does not govern
Communication Standards
Everymind / Mindframe
Co-authoring AOD communication guidelines. Extending Mindframe's evidence-based suicide reporting standards into drug harm reduction: alert language, stigma reduction, public messaging. A natural partner for how the Hub speaks, not just what it distributes.
Access (limited)
Justice
Harm reduction framing only. No individual-level surveillance
Access (public)
General Public
Harm reduction info, drug alerts, service finder. Read-only, no personal data required

Evidence Base

This architecture isn't speculative. It's grounded in published, peer-reviewed research, including work Ed Broadbent co-authored.

Emerging Evidence: Why Now

Recent research across 7 domains independently validates the Hub's architecture. No single paper proposes the whole system. But taken together, they describe exactly what needs to be built.

CONFIRMED: International First

No peer-governed national harm reduction information system exists globally

EU Early Warning System (EUDA), DIMS (Netherlands, since 1992), TEDI (20 NGOs, 13 countries), WEDINOS (Wales): all place governance with government or research institutions. Peers serve in advisory or staffing roles, never governance. A peer-governed Hub would be the first.

EU EWS · DIMS/Trimbos · TEDI · WEDINOS
Critical: Jan 2026

"Such systems must be led by communities"

Freestone, Zhou, Kypri et al. studied 20 Australian EWS practitioners + 14 peer-org staff. Found systematic collection of experiential reports from PWUD improves drug-related EWS, but must be underpinned by strong governance and led by communities.

Freestone, Zhou, Kypri et al., International Journal of Drug Policy, January 2026
Differentiated Feeds

One-size-fits-all alerts fail

Volpe, Brien, Grigg et al. found practitioners experience alert fatigue from undifferentiated drug warnings. Called for mechanisms to target alerts to relevant audiences, by information type, drug type, or role. The Hub's tiered feeds are evidence-based, not arbitrary.

Volpe, Brien, Grigg et al., Harm Reduction Journal, 2023
NPS Gap

Australia's monitoring lacks responsiveness

EDNA researchers found that current monitoring modalities in Australia (surveys, wastewater monitoring, coronial investigations) lack the specificity and responsiveness required for an effective early warning system. Community reporting fills the speed gap.

Smith et al., International Journal of Drug Policy, 2025 (EDNA-V)
Speed of Detection

First-ever 5-cyano isotodesnitazene detected in under 2 weeks

Collaboration between drug checking services and academia identified a never-before-seen nitazene analogue in street drugs within 14 days. The study found that universities provide the scientific expertise and infrastructure necessary to confirm molecules detected by drug checking services. The Hub systematises this collaboration at national scale.

Scientific Reports, January 2026
Composite Intelligence

Wastewater + community = better than either alone

Wastewater-based epidemiology research demonstrates that sewage monitoring algorithms can provide days of early warning before overdose spikes are detected by health systems. Combined with community signal (near-instantaneous), the Hub extends warning windows further. Data triangulation research confirms that combining multiple data sources reveals findings that any single dataset would miss.

Bade et al., Nature Water, 2023 · Castiglioni et al., Drug & Alcohol Dependence, 2015
Mental Health Bridge

"I didn't even know headspace had the drug thing until today"

Study participants at Headspace didn't know AOD services existed. Practitioners reported limited AOD knowledge and low confidence. The Hub's intelligence feed to mental health and allied health settings addresses a documented, dangerous gap. An RSS feed from the Hub to Headspace centres alone would connect youth mental health workers to real-time drug harm intelligence they currently don't receive.

ScienceDirect, 2023 · Headspace AOD Access Study
Communication Gap

Australia has Mindframe for suicide. Nothing equivalent for AOD.

Everymind's Mindframe guidelines set the standard for responsible media reporting on suicide and mental health. The AOD sector has no nationally agreed communication guidelines for drug warnings, alert framing, or public messaging about substance use. Current drug alerts vary wildly in language, tone, and stigma awareness across jurisdictions. The Hub creates the technical infrastructure for coordinated alerts, but co-authored AOD communication guidelines with Everymind/Mindframe would ensure those alerts meet the same evidence-based standards that suicide prevention messaging already does.

Everymind / Mindframe · Gap analysis
Governance = Speed

Fragmented governance causes preventable deaths

The PRN co-design documented that "delays in detection and response within public-health frameworks focused on harm reduction have contributed to stigmatizing and alarmist media responses." When governance is unclear, media panic fills the void. Clear Hub governance = faster, more accurate response.

Siefried et al., Frontiers in Public Health, 2025

Existing Alignment: Why This Hub, Why AIVL

This isn't a cold pitch. It's built on an existing working relationship and consistent community alignment across the Prompt Response Network.

John Gobeil supported Ed's PRN role

AIVL's John Gobeil actively supported Ed's appointment to coordinate the Prompt Response Network, recognising the value of someone who understood both the technical infrastructure and the community governance it needed to serve.

AIVL chaired the PRN advisory group

Ed supported AIVL's role as chair of the PRN advisory group. Community voice held structural authority in the network's governance from the start.

Listened to Molly: 10x The Know's audience

When AIVL's Molly identified the need for wider drug alert dissemination, Ed facilitated the RSS feed infrastructure and sharing mechanisms that expanded The Know's reach tenfold. That network then spread further through ADF, Pill Testing Australia, and other partner organisations, ensuring AIVL retained direct access to the distribution channel.

Consistent lived experience alignment

Across every PRN decision (governance structure, data sharing tiers, alert distribution, advisory composition), Ed consistently prioritised community voice and lived experience. Not as a compliance exercise. As architecture.

Data Feeds

Seven data streams converging into a single harm reduction intelligence picture. Each feed has different cadence, format, and reliability. The hub normalises and correlates them.

Composite Signals

No single feed tells the whole story. When multiple independent data sources converge on the same substance, region, or time window, that's a composite signal. The hub makes convergence visible.

COMPOSITE SIGNAL Western Sydney | Nitazenes | Feb 2026
Drug Alert Feed
Nitazenes detected in counterfeit oxycodone tablets, Inner West Sydney. Three ED presentations, severe respiratory depression, naloxone required in all cases.
Feb 20

Feb 17
Treatment Data

Feb 21

Hub Synthesis

5 independent feeds converging on nitazene-class synthetic opioids in Western Sydney within a 7-day window. No single feed generated this picture. The composite signal is visible only because the hub correlates across sources.

Recommended action: National-level alert via Prompt Response Network. Targeted harm reduction messaging to Western Sydney AOD services. Naloxone distribution advisory (standard doses may be insufficient for nitazene exposure).

Without the Hub

  • ED sees overdoses but doesn't know about the pill testing results
  • Drug checking finds nitazenes but doesn't see the treatment data spike
  • Community reports on Discord. Never reaches health services
  • Wastewater data published quarterly, 3 months after the event
  • Each agency writes its own alert. No coordination. No composite picture.

With the Harm Reduction Hub

  • All feeds visible in one place. Convergence is automatic
  • Community signal weighted and routed to health services
  • Drug checking results connected to treatment presentations
  • Wastewater trend data adds population-level context
  • One coordinated alert. One composite signal. One response.

Governance & Access

Access to platform data is calibrated to role and accountability. The public tier is deliberate: harm reduction information should be universally accessible without requiring identity disclosure.

Why This Tier Structure

Peers access pill testing data

CheQpoint research (Puljević et al.) showed participants were "highly motivated to use drug checking" and would "employ more harm reduction strategies following an unexpected test result." Peers submit samples. Peers see results. Not locked behind clinical tiers.

Peers report signals

Freestone, Zhou, Kypri et al. (Jan 2026): "Such systems must be underpinned by strong governance, remain open to collecting reports of benefits plus harms and be led by communities." The anecdotal reporting system is a peer-tier function: community-governed, anonymous, accessible.

Researchers earn access

Data justice framework (Buchbinder et al.): "Empowering stakeholders to participate in the design and implementation of data infrastructure and governance is critical for advancing a data justice agenda." Research access is granted by AIVL governance, not assumed by institutional affiliation.

Government receives reports, not raw data

PRN co-design: "A common focus on preventing and minimizing drug-related harms, rather than pursuing other agendas." Policy tier gets facilitated reporting: jurisdictional analytics, not individual records. The hub reports to government; government does not surveil through the hub.

Data Sovereignty Framework

Data owner: the individual
Data custodian: the community
Health and research access is granted, not assumed
Public access is read-only. No personal data required
Justice access is strictly harm reduction framed. No surveillance function
Australian-hosted infrastructure. Data does not leave Australian jurisdiction

Status & Next Steps

Current Status
Concept stage. Working document for development with AIVL and relevant partners.
Immediate Priority
The PRN Drug Alert Report (Q1 2025) proved national coordination works. The RSS infrastructure that expanded The Know's audience tenfold is already live. The next step is community-led hosting, the signal register, and co-design of AOD communication guidelines with Everymind/Mindframe.
Contingent On
AIVL appetite to host and steward nationally. Everymind engagement on AOD communication guidelines. DOHAC receptiveness to community-governed infrastructure funding. Co-design with peer communities across all states and territories. Mental health sector engagement (Headspace, Beyond Blue). Funding pathway.

Let's build this together.

The Harm Reduction Hub is a concept ready for co-design. If you're from AIVL, ADF, a peer organisation, health service, or government body interested in community-governed harm reduction infrastructure? Let's talk.
