Public Health focuses on preventing disease and promoting the health of the population through the organised efforts of society. This differentiates it from the practice of personal healthcare, as it involves collective action across sectors and disciplines, with a focus on populations and communities. It has a strong focus on health equity, and reducing ethnic and socioeconomic inequalities in health.
Why study Public Health?
Public Health practitioners work in a range of areas in the wider health sector including in government and non-government organisations. Front line practitioners include policy analysts, health promoters, community health workers and staff working in environmental protection. A number of Public Health major graduates will decide to pursue post-graduate qualifications such as the Postgraduate Diploma in Public Health (DPH) and Master of Public Health (MPH), and further careers in public health research.
