Unacknowledged Casualties

The ADF Quinoline Drug Trials and the Families Left Behind

Between 1998 and 2002, approximately 3,000 members of the Australian Defence Force were given powerful antimalarial drugs — mefloquine and tafenoquine — during deployments to East Timor and Bougainville. In significant part, these were clinical drug trials conducted by the Army Malaria Institute. The personnel who received the drugs were not always adequately informed of the risks. Many were not informed at all.

Both drugs are now recognised by regulatory agencies in Australia, the United States, and Europe as carrying substantial neuropsychiatric risk. The US Food and Drug Administration issued its strongest possible warning for mefloquine in 2013. Research conducted by the same institute that developed tafenoquine found it to be more neurotoxic than mefloquine.

The harms documented among affected veterans include chronic depression, paranoia, psychosis, personality change, dissociation, aggression, and suicide.

They also include domestic violence.

This site addresses what that means for the people who were not on deployment — the partners and spouses who came home to someone changed, who lived with consequences they did not choose and were never warned about, and who have never been recognised by any institution as having been harmed.

The spouse is not a footnote in this story. She is its other casualty.

What This Site Is

This is a public-interest research site based on a comprehensive research report synthesising peer-reviewed scientific literature, regulatory agency documentation, Australian Senate inquiry submissions, coronial records, forensic psychiatric literature, and veteran advocacy evidence.

It is designed to be useful to journalists, policymakers, affected families, and the general public. It distinguishes carefully throughout between what is scientifically established, what is a plausible mechanism, what is documented case evidence, and where genuine uncertainty remains. It does not overstate the evidence. It does not minimise it either.

A note on evidential standards is set out below. Readers are encouraged to consult it before drawing conclusions from any page on this site.

Where Would You Like to Start?

For journalists and researchers
The science is real, the regulatory record is public, and the institutional failures are documented. Begin with The Issue for an overview, or go directly to The Drugs for the scientific and regulatory foundation. Documented Cases and System Failures are designed with your verification needs in mind. The full research report is available to download below.

For affected families
If you are a partner or former partner of an ADF veteran who served in East Timor or Bougainville, and you recognise something of your experience in what this site describes, you are not alone and you are not invisible here. Start with The Spouse — a page written specifically about the long-term effects on partners — or with The Household, which describes the behavioural patterns that have affected so many families. A dedicated page For Families is also available, with information about support.

For policymakers and legal professionals
The gaps in the current system are specific, documented, and in several cases addressable through existing legislative and regulatory mechanisms. System Failures analyses what each relevant institution currently cannot see or do. Misdiagnosisaddresses the treatment and entitlements consequences of the wrong diagnosis. What Must Change sets out the findings and seven specific recommendations. The International Record provides comparative context.

A Note on the Evidence

This site uses four evidential registers, which are identified on each page:

Established fact — findings confirmed by peer-reviewed science, regulatory agency determinations, or official parliamentary and coronial records.

Plausible mechanism — a biological or clinical pathway that is consistent with the scientific literature and offers a credible explanation, but has not yet been demonstrated by a direct study in this specific population.

Documented case evidence — cases or patterns recorded in advocacy submissions, parliamentary testimony, or media records, which have not been independently verified by this site but are accurately represented as sourced.

Area of uncertainty — questions the current evidence does not resolve, identified honestly rather than papered over.

The central claim of this site — that the neuropsychiatric effects of mefloquine and tafenoquine are a serious, under-investigated contributor to domestic harm in affected ADF families — rests on established regulatory fact and a plausible neurobiological mechanism. The direct causal chain in individual cases is not asserted beyond what the literature supports.

The Royal Commission and What Remains

In September 2024, the Royal Commission into Defence and Veteran Suicide tabled its Final Report. Volume 4, Chapter 22 addressed mefloquine and tafenoquine directly, and recommended that Defence and the Department of Veterans' Affairs establish a brain injury program for serving and ex-serving members exposed to these drugs. In December 2024, the Australian Government accepted or agreed in principle to 104 of the Commission's 122 recommendations, and work on the brain injury program is reported to be underway.

This is a significant development. It is not the end of the story.

The Royal Commission's recommendations address veterans. They do not yet extend formal recognition to the partners and families who have carried their own share of the consequences. The brain injury program's scope, funding, and delivery remain to be tested. The systemic gaps in domestic violence services, family law, and veterans' entitlements that this site documents remain in place.

This site builds on the Royal Commission's findings. It asks what comes next.

This site was prepared in 2026. It incorporates findings from the Royal Commission into Defence and Veteran Suicide (Final Report, September 2024) and the Australian Government response (December 2024).
