10 careers in preventative health: explore roles that help build a healthier future

Preventative health careers are a rewarding way to help people stay well, avoid illness and protect the health of future generations. If you're looking for a rewarding career path with a focus on disease prevention, health education and improving the overall wellbeing of Australians, a role in preventative health could be ideal for you. This article explores 10 careers in preventative health and how each role promotes a healthier future for individuals, communities and Australian society.

What is preventative health?

Preventative health is a diverse field, with roles spanning across the public health sector, allied health field and in primary healthcare. Preventative health careers allow healthcare professionals to make a meaningful impact on an individual and broad scale. Australian Government data shows that almost half of Australians have one or more chronic diseases that could be prevented, which means career opportunities to make a difference are robust.

1. Communicable disease analyst

A communicable disease analyst helps protect the public through disease monitoring and analysis of pathogen transmission routes. These professionals may investigate diseases such as influenza, HIV or measles. They collect data from various sources, identify patterns and provide this information to government advisors and health authorities, who can develop response and mitigation measures. The long-term gain of a communicable disease analyst is vital to the health of individuals, communities and populations. The analysis of disease trends helps refine public health strategies and policies. Their work informs the creation of more effective vaccination programs, pandemic preparedness plans and public education campaigns.

Postgraduate courses for preventative health careers

Postgraduate study can equip you for a role in preventative health. Several leading institutions provide high-calibre education at the forefront of public health. Below is a summary of key educational institutions mentioned in the material:

Institution	Key Achievement / Focus
University of Technology Sydney (UTS) Online	Top 100 University Globally (QS World University Rankings, 2025)
The Faculty of Public Health at Mahidol University	First public health academic institution in Thailand (established 1948)
Rollins School of Public Health at Emory University	Ranked 3rd among all accredited schools and programs of public health in the US

For example, UTS Online’s Graduate Certificate in Public Health and Communicable Disease is designed for professionals who want to develop a fundamental understanding of epidemiology and population health. This course equips you with the skills to address infectious disease threats with strategies for prevention and effective outbreak response, encouraging better health outcomes for people across diverse settings.

Global Health Education Program (G-HEP)

The “Global Health Education Program (G-HEP)” vision is to establish a global community of young leaders that can work together to push global health agendas forward and to conduct human resources training and development for the future. Participants in G-HEP can work together to deepen mutual understanding and cooperation for solving complex global public health issues. In 2024, the program welcomed Emory University Rollins School of Public Health, bringing a U.S. perspective to the program along with participants of diverse professions and backgrounds.

Planetary Health Initiatives

The HGPI Planetary Health Project was formed to contribute to the promotion of human health and the realization of a more sustainable society. It promotes the concept of planetary health through three pillars: (1) climate change; (2) loss of biodiversity; and (3) environmental pollution. International cooperation is more important than ever because no country can address climate change by itself.

Design and Global Health: Complementary Approaches

The global health community develops solutions by continuing to learn through research and/or implementation science. The design process provides global health practitioners with new perspectives on health challenges and enables a rapid translation of insights into prototypes and solutions that can be tested and refined. Design can be applied differently depending on challenges:

• Design as Spark: Apply design methods to spark new ideas, thinking, concepts or to deliver specific outputs as part of a larger program.
• Design as Ingredient: Design is used in combination with other approaches across the program cycle.
• Design as an End-to-End Process: The program is scoped to match the design process through its entire cycle.

Design for Health is a global group of funders, implementers, and designers committed to increasing the understanding, appropriate use, and value of design as an approach to help achieve global health goals. The design process can surface key questions that help programs incorporate the needs and expectations of those for whom the program is designed for, ultimately increasing the likelihood of impact.
