Australia's first diphtheria death in nearly a decade and ongoing outbreak in Northern Territory
Consensus Summary
Australia is experiencing its first diphtheria-related death in nearly a decade, with the fatal case occurring in the Northern Territory (NT) in a remote area. The NT has declared an outbreak of the disease, marking the first since the 1990s, with over 100 cases reported and some patients requiring intensive care. The majority of seriously ill patients are unvaccinated or have missed booster shots, highlighting the importance of vaccination. Nationwide, 161 cases have been recorded, primarily affecting Indigenous residents in remote areas. Both sources confirm the last diphtheria death in Australia was in 2018, involving an unvaccinated adult. The NT’s healthcare system is under strain, with clinics diverting resources to address the outbreak. Federal assistance is being mobilized to accelerate vaccination efforts, particularly for vulnerable populations. The diphtheria vaccine, which also covers pertussis and tetanus, remains the primary tool to control the outbreak.

Key details reported by multiple sources:
- A person died from diphtheria in Australia for the first time since 2018, confirmed by John Boffa (Central Australian Aboriginal Congress) and ABC News.
- The deceased was from the Northern Territory (NT) and died in a remote area within the past few weeks (exact date not specified).
- The NT reported over 100 cases of respiratory and cutaneous diphtheria, with some patients requiring intensive care admission.
- The majority of seriously ill patients were either unvaccinated or missed their booster window, per Dr. John Boffa.
- Australia has recorded 161 total diphtheria cases nationwide, with cases in NT, Western Australia, Queensland, and South Australia.
- The last diphtheria death in Australia was in 2018, involving an unvaccinated adult with respiratory diphtheria, according to the Australian Centre for Disease Control.
- The NT declared a diphtheria outbreak in March 2026, the first since the 1990s.
- Over 98% of diphtheria cases in Australia are Indigenous residents living in outer regional, remote, or very remote areas.
- The diphtheria vaccine is available in Australia as a combination vaccine covering diphtheria, pertussis, and tetanus.
Points of Difference
Details reported by only one source:
- Dr. Boffa stated that the NT's primary healthcare clinics are struggling to deliver routine care and are diverting resources to the outbreak due to lack of surge workforce or additional resources.
- The article mentions vaccine hesitancy since COVID-19 as a potential contributing factor to the outbreak.
- Federal resources are 'on the way' to assist with vaccinations and boosters, with the Commonwealth committing significant additional funds to the NT over six months.
- Dr. Boffa explicitly mentioned that some late adolescents (who had their last dose at age 12) and adults (who haven’t had a booster in over five years) are at higher risk.
