Australia is currently experiencing its most severe diphtheria outbreak in decades, with nearly 220 cases reported across the Northern Territory, Western Australia, South Australia, and Queensland. This resurgence of the Victorian-era disease is primarily attributed to a significant decline in childhood vaccination rates, which hit a five-year low in 2025.
Disproportionate Impact on Indigenous Communities
A substantial majority of the reported cases involve Indigenous Australians. In response, health authorities are collaborating with Aboriginal agencies to enhance immunisation efforts and address the underlying causes of low vaccination uptake.
Government Response and Support Package
Federal Health Minister Mark Butler has confirmed that a government support package is being developed. This package includes additional vaccine supplies and a surge workforce to assist in containment and treatment. Minister Butler noted that approximately 25% of cases require hospitalisation, underscoring the severity of the outbreak.
Health authorities are also investigating a suspected diphtheria-related death. If confirmed, this would mark the country's first fatality from the disease in nearly a decade, highlighting the urgent need for effective public health interventions.
