Australia is grappling with its worst diphtheria outbreak in decades, primarily affecting remote Indigenous communities. As reported by The Guardian, over 245 cases have been recorded in 2026, with a significant majority occurring in the Northern Territory and other northern regions of Australia.

According to BBC News, health officials confirmed the first diphtheria death since 2018. The outbreak has also spread to Western Australia, South Australia, and Queensland. Health Minister Steve Edgington stated that the government is taking the situation seriously and working to contain it.

The overwhelming majority of patients are Aboriginal people living in remote communities, where overcrowded housing and poor environmental health conditions facilitate the spread of infectious diseases. UPI reported that vaccination rates among Aboriginal children have improved since the COVID-19 pandemic began, with about 90% of Aboriginal and Torres Strait Islander children aged two to five fully immunized.

The outbreak has highlighted the pressures faced by Aboriginal community-controlled health services, which are crucial in delivering primary healthcare. A report commissioned by the Aboriginal Medical Services Alliance Northern Territory found that most health services had to reduce core services due to workforce shortages. The commonwealth's $7.2 million emergency support package aims to bolster vaccination efforts and provide surge workforce support.
