About the Western Public Health Unit
The Western Public Health Unit (WPHU) supports Victoria’s public health strategy within the central and western suburbs of Melbourne, with a particular focus on disease prevention and population health. Our aim is to protect health, create healthy environments, address health inequities and promote wellbeing for the catchment we serve.
WPHU is one of nine local public health units (LPHUs) established in 2020 during the COVID-19 pandemic to manage local cases and outbreaks of COVID-19. In 2022, WPHU took on additional public health responsibilities for other notifiable conditions and broadened our scope to include population health promotion.
Housed within Western Health, WPHU uses local insights, community-based relationships and direct engagement to tailor and deliver high-quality, evidence-based public health initiatives and respond to incidents and issues within our catchment. We work closely with local health services, primary and community health services, other state government agencies, local government and local communities.
WPHU’s health protection role involves protecting individuals, groups and populations against emerging health threats related to infectious diseases and the environment. This involves surveillance and monitoring of infectious diseases, responding to case investigations and outbreaks, strategic health protection work and outbreak planning as well as education and training for healthcare professionals and communities.
By December 2023, WPHU will have accountability for the control of all notifiable conditions except tuberculosis, anaphylaxis and high-lead levels. This includes all vaccine-preventable diseases, blood-borne viruses, sexually-transmissible infections, zoonoses, vector-borne diseases and enteric disease, as well as antimicrobially resistant pathogens.
Medical practitioners and pathology departments are still required to notify conditions to the Victorian Department of Health in accordance with the Public Health and Wellbeing Act 2008. WPHU is empowered to receive notifications of notifiable conditions from medical practitioners and laboratories, undertake case management, contact tracing and outbreak management. Notifications are allocated immediately to the relevant local public health unit or the Department of Health as appropriate. Alternatively, notifiers can call WPHU directly on 1800 497 111 to notify, especially in cases of urgent notifications or where a direct conversation is desired. The WPHU team is available and keen to provide advice and assistance to local medical practitioners about any aspect of the public health management of communicable diseases within our scope.
WPHU’s catchment includes two important international ports of entry – Port of Melbourne and Melbourne Airport. We work with the Department of Agriculture Fisheries and Forestry, other government and non-government stakeholders, as well as the Department of Health and other local public health units to prevent the entry and spread of infectious diseases to Australian communities.
Population health promotion
WPHU’s population health role involves promoting health and wellbeing and preventing disease in local communities, contributing to the Victorian Government’s vision that Victorians are the healthiest people in the world.
Our new Population Health Catchment Plan sets out priorities and proposed actions for population health promotion over the next 6 years. Our three focus areas for initial action include: improving food systems and healthy eating; reducing tobacco-related harm and vaping; and climate change and its impact on health. The focus areas are directly connected to preventing avoidable chronic diseases such as heart disease, type 2 diabetes, some cancers and dental caries, and are well suited to a focus on primary prevention or keeping people well.
WPHU will use a collective impact model, bringing together local partners (councils, health and community services, and communities) to align resources, skills and knowledge for the achievement of catchment priorities. These collective efforts are supported through a partnership structure – the WPHU Population and Preventive Health Network. The network is comprised of a population and preventive health reference committee and three action groups dedicated to the initial focus areas. The action groups are open to all catchment stakeholders and will provide a dedicated space to share insights and evidence-based initiatives, co-design interventions and boost collective action across the catchment.
WPHU comprises a multidisciplinary team with expertise in medicine and public health, data and epidemiology, infection prevention, health promotion, community engagement and bi-cultural work, communications, operations and administration. Several members of the team are registered health professionals such as nurses, doctors and allied health professionals, and many have specialist qualifications in public health.
