For nearly four decades, Australia’s approach to managing infectious diseases was described by experts as a patchwork—fragmented, inadequate, and often poorly coordinated. The warning was first sounded prominently in 1987, when epidemiologist Prof Robert Douglas wrote in the Medical Journal of Australia that the nation desperately needed a centralized system to prevent disease and minimize its effects. He argued that state and federal governments needed a shared strategy to avoid the chaos of disconnected responses.
That vision has finally materialized with the establishment of the Australian Centre for Disease Control (CDC). Launched in January as a statutory, independent commonwealth authority, the agency is designed to be the nation’s primary shield against health emergencies, overseeing national health surveillance, pandemic preparedness, and public health advice.
At the helm of this historic institution is Prof Zoe Wainer. A cardiothoracic surgeon with a master’s in public health, Wainer stepped into the role of director general with a clear mandate: to ensure the country is never caught off guard by a biological threat. “The role is to ensure that Australia is never surprised by a health threat, never isolated in responding to a health threat, and always contributing to a stronger regional and global public health system,” Wainer said.
The timing of the agency’s launch is critical. Wainer takes over at a moment when the intersection of climate change and social instability is creating new vulnerabilities. From the spread of Japanese encephalitis beyond the Torres Strait to a resurgence of preventable diseases like measles fueled by vaccine hesitancy, the challenges are as much about sociology and trust as they are about virology.
Closing the data gap and the ‘One Health’ vision
One of the most urgent priorities for the Australian Centre for Disease Control is the modernization of how the country tracks illness. During the Covid-19 pandemic, a recurring weakness was the lack of real-time data sharing between state and federal jurisdictions, which often led to delayed responses and conflicting advice.
Wainer has identified the integration of these disparate data streams as a primary objective for the agency’s early years. “It’s a massive project of ours to really try to bring that data linkage together,” she said.
Beyond digital surveillance, the agency is adopting a “One Health” framework. This holistic approach recognizes that human health is inextricably linked to the health of domestic animals, wildlife, and the broader environment. By breaking down the silos between veterinary science, environmental ecology, and human medicine, the CDC aims to catch zoonotic spillovers—diseases that jump from animals to humans—before they become outbreaks.
This perspective is also driving the agency’s commitment to collaborating with First Nations people. Wainer noted that Aboriginal and Torres Strait Islander communities have maintained a deep understanding of the connection between land, water, climate, and animal health for tens of thousands of years, offering a blueprint for the One Health approach.
The battle against health misinformation
Perhaps the most complex challenge facing the new agency is the erosion of public trust. Prof Brett Sutton, director of CSIRO’s health and biosecurity unit, has described the current wave of misinformation as a “very substantial threat” to national security.
Wainer believes the antidote to this distrust is radical transparency. Rather than simply issuing directives, she envisions a dialogue where the agency acknowledges community concerns and explains the “why” behind the science. “I feel transparency is a really important part [of the solution to misinformation] … to have that conversation with the community and not expect them to necessarily take on what we say,” Wainer said.
This commitment to independence is intended to insulate the Australian agency from the political volatility seen in other nations. Wainer has remained focused on the domestic mission, avoiding comparisons to the political upheavals surrounding the U.S. CDC, stating that decisions made by the United States government are a matter for that country.
| Year | Key Event / Milestone | Impact |
|---|---|---|
| 1987 | Prof Robert Douglas report (MJA) | First major call for a coordinated national system during the HIV peak. |
| 2010-2017 | AMA and medical body advocacy | Repeated calls for a CDC following swine flu and seasonal influenza. |
| 2020-2022 | Covid-19 Pandemic | Exposed critical gaps in real-time state-federal data sharing. |
| 2025 | Establishment of Australian CDC | Launched as an independent statutory authority in January. |
A legacy of social justice in medicine
For Prof Wainer, the leadership of the CDC is not just a professional milestone, but the culmination of a lifelong trajectory rooted in social justice. Her approach to public health was shaped by her parents, both of whom were trailblazers in medical advocacy.
Her father, Dr Bertram Wainer, was a prominent women’s health advocate who risked his life in the 1960s and 70s to expose corruption in illegal abortion networks and establish Australia’s first public abortion clinic. Her mother, Dr Jo Wainer, a social scientist and former ABC journalist, continued this work by researching sex differences in medical research and establishing multidisciplinary clinics.
“Mum and Dad did extraordinary work in the name of public health,” Wainer said. “I always end up in public health in my career. It’s just been a trajectory.”
This family legacy of fighting for the marginalized has informed Wainer’s own clinical work. As a cardiothoracic surgeon, she conducted seven outreach missions to lower- and middle-income countries to treat children with congenital disorders and rheumatic heart disease—a preventable condition that still plagues remote Indigenous communities in Australia and disadvantaged regions across Africa and Asia.
Before her appointment to the CDC, Wainer served as the deputy secretary for community and public health in the Victorian Department of Health, where she led the state’s first inquiry into women’s pain, further cementing her focus on health equity.

As the Australian Centre for Disease Control begins its operational phase, the next critical checkpoint will be the rollout of the integrated national data linkage system, which aims to provide the real-time surveillance capabilities the country lacked during previous crises.
