Australia Faces 'Biggest Diphtheria Outbreak' in Decades
Health authorities are expanding vaccination, booster and contact-tracing efforts as 25% of cases have been hospitalised, officials said.
- Australia recorded 226 diphtheria cases across the Northern Territory, Queensland, South Australia, and Western Australia on Wednesday, with Federal Health Minister Mark Butler describing the outbreak as "serious."
- Falling vaccination rates, which hit a five-year low in 2025, drive the outbreak, compounded by overcrowding and limited health access in remote Aboriginal communities.
- Since January 1, 94 per cent of cases involved Aboriginal and Torres Strait Islander people, with approximately 25 per cent of patients requiring hospitalization for the contagious respiratory illness.
- Minister Butler is finalizing a federal support package including surge staffing and additional vaccines, partnering with the Northern Territory government and Aboriginal-controlled health services.
- A suspected diphtheria-related death in the Northern Territory remains under investigation, which if confirmed would mark the first fatality from the disease in Australia in almost a decade.
