Australian Centre for Disease Control: Centralizing Health Security and Pandemic Preparedness

The establishment of the Australian Centre for Disease Control (CDC) marks a fundamental shift in the nation’s approach to health security, ending a decades-long period of systemic fragmentation. The move toward a statutory, independent commonwealth authority addresses a vulnerability that has persisted since at least 1987, when Prof Robert Douglas described disease control as “fragmented, inadequate and poorly coordinated”, lamenting a lack of national coordination.

At the time, Douglas advocated for a centralized strategy, writing, “Now is the time to begin to plan for a national system of disease control,” and urging state and federal governments to share a strategy and “play their proper roles in the prevention of disease and the minimisation of its effects”. His argument, largely ignored for a generation, has now been effectively written into the architecture of national health governance.

The transition to a centralized model follows a history of reactive responses to various health crises, including swine flu, mpox, and seasonal influenza. The new agency, led by Director General Prof Zoe Wainer, is designed to provide a cohesive layer of oversight for national health surveillance, pandemic preparedness, and public health advice. It sits alongside, and is intended to complement, existing powers under the Biosecurity Act 2015, giving the Commonwealth a permanent public health institution to match its emergency legal toolkit.

Bridging the Federal-State Data Divide

A primary objective for the CDC is the resolution of chronic data silos. During the Covid-19 pandemic, the absence of real-time, interoperable data sharing between state and federal jurisdictions created significant blind spots in the national response and complicated cabinet-level decision-making. To mitigate this, the agency is prioritizing the integration of surveillance systems to ensure a unified operating picture during health emergencies and routine outbreaks alike.

“It’s a big project of ours to really try to bring that data linkage together,” Wainer says, describing work that cuts across state health departments, the Australian Bureau of Statistics and other federal agencies.

Regarding the scale of the investment, Wainer describes the agency as “an extraordinary opportunity and investment that the nation’s made to keep Australia safe from public health threats and emergencies,” noting that “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.” For policy-makers, the promise is a shift from improvised crisis structures to standing capability that endures beyond election cycles.

The One Health Framework and Environmental Risk

The CDC is adopting a One Health approach, a multidisciplinary strategy recognizing that human health is inextricably linked to the health of animals and the shared environment. This framework is critical for monitoring zoonotic diseases-infections that jump from animals to humans-which are increasingly frequent due to climate change and habitat encroachment.

Current environmental drivers are already impacting Australian public health, with climate change facilitating the spread of infections such as Japanese encephalitis from the Torres Strait to the mainland. The One Health approach necessitates collaboration between veterinary scientists, ecologists, and medical professionals to identify pathogens before they trigger human outbreaks, and to ensure these risks are reflected in planning decisions spanning agriculture, water management and border control.

This holistic perspective extends to partnership with First Nations communities, who possess deep ancestral knowledge of ecological interdependencies. “My understanding, from speaking to many Aboriginal and Torres Strait Islander people, is that they’ve understood that deep connection between land, water, climate, people and animals for tens of thousands of years,” Wainer says. Embedding this knowledge in formal risk assessments is framed as both a public health and reconciliation imperative.

Countering Misinformation and Public Distrust

The agency arrives at a juncture where the erosion of trust in scientific institutions is actively compromising population health and complicating government communication strategies. Misinformation has contributed to the resurgence of preventable diseases, most notably measles, by undermining vaccination uptake and fuelling resistance to evidence-based mandates.

Prof Brett Sutton, director of CSIRO’s health and biosecurity unit, has identified this trend as a “very substantial threat”. Wainer acknowledges the difficulty of the landscape, stating, “It’s a really challenging area for all of us.”

To address this, the CDC aims to utilize its independence from direct government political cycles to foster transparency and more durable public engagement. “I think 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. We have to be able to understand what the concerns of community are,” Wainer says. “We’re pretty confident that as we build the CDC, we will work very closely with our stakeholders to try to understand, if there is a lack of trust, what might be driving that.”

Addressing Systemic Health Inequity

The CDC’s mandate includes addressing the social determinants of health that leave certain populations more vulnerable to disease. This is particularly evident in the persistence of rheumatic heart disease, a preventable condition that disproportionately affects remote Indigenous communities in Australia and impoverished regions globally.

• Population Vulnerability: Higher prevalence in areas with overcrowding, insecure housing and poor access to primary care.
• Prevention Gaps: Lack of early intervention for streptococcal infections and fragmented follow-up for at-risk children.
• Systemic Barriers: Geographic isolation, workforce shortages and cultural gaps in healthcare delivery.
• CDC Objective: Integrating social justice and equity into national surveillance to identify and resource high-risk clusters, and to inform targeted funding agreements with states and territories.

Wainer’s commitment to these issues is rooted in a personal and professional trajectory informed by social justice. Her father, Dr Bertram Wainer, was a prominent women’s health advocate who established Australia’s first public abortion clinic and exposed systemic corruption in the 60s and 70s, often facing threats to his life. Her mother, Dr Jo Wainer, a social scientist and ABC journalist, focused on sex differences in medical research and the experiences of rural doctors.

“Mum and Dad did extraordinary work in the name of public health,” Wainer says. “I always end up in public health in my career. It’s just been a trajectory.”

With a background as a cardiothoracic surgeon and experience as the deputy secretary for community and public health in Victoria, Wainer has previously led inquiries into women’s pain and conducted outreach missions to operate on children with congenital disorders in low-income countries. Colleagues describe her as comfortable moving between the operating theatre, bureaucracy and community settings-an asset for an institution that must speak to cabinet rooms as well as clinics.

“I’ve always looked at next career moves as: ‘How can I take the skills, my attributes, my experience, and contribute it to the best benefit of my community?’”, Wainer says. “When the opportunity came up to be the inaugural director general for the Australian Centre for Disease Control, I absolutely jumped at it, because it meets that kind of internal value set that I have.” The test for Australia’s new CDC will be whether that personal ethos can be translated into durable systems, measurable outcomes and a national culture that treats public health preparedness as core infrastructure, not a temporary response to the last crisis.
