Western Australia health officials are urging vulnerable Indigenous communities to receive diphtheria boosters as an outbreak spreads through the state's far-north region [1].
The drive targets the Kimberley and Pilbara areas, where health authorities said disinformation is lowering vaccine uptake. Because diphtheria can be fatal, the push aims to prevent further deaths among populations with limited healthcare access.
National figures indicate the scale of the crisis has grown significantly. There have been more than 220 reported cases of diphtheria across Australia [3]. The outbreak has also reached the Northern Territory, where officials recorded one death — the first diphtheria death in Australia in almost a decade [4].
The Western Australia Department of Health is coordinating the effort with local Aboriginal health services [1]. These agencies are working to counter misinformation that has discouraged some residents from seeking medical intervention. The goal is to increase the number of people receiving booster shots to create a stronger wall of immunity in remote regions.
Public health officials said that the disease is expanding across the country [2]. The combination of geographic isolation in the far north and the spread of false information about vaccine safety has created a critical vulnerability for Indigenous populations.
While the outbreak is centered in Western Australia's far north, the recent fatality in the Northern Territory suggests a wider regional health crisis [1, 4]. Health services continue to prioritize the distribution of vaccines to those most at risk of severe complications from the disease.

The resurgence of diphtheria in Australia highlights a critical gap in public health infrastructure and the dangerous impact of vaccine disinformation in remote areas. The spread from Western Australia to the Northern Territory suggests that the outbreak is no longer localized, requiring a coordinated national response to protect marginalized populations who are disproportionately affected by preventable diseases.
