An outbreak of Legionnaires’ disease in Potts Point, a central suburb of Sydney, has led to the death of an 86-year-old man and the hospitalization of six others, according to health authorities. The South Eastern Sydney Local Health District (SESLHD) reported that the affected individuals, aged between 45 and 95, fell ill after potential exposure to contaminated water particles between May and July 2025. All patients are residents or recent visitors of Potts Point, though none are known to each other.
The 86-year-old man became unwell in late June and sadly succumbed to the infection. Of the six remaining patients, five have been discharged from the hospital, while the sixth continues to recover. SESLHD has expressed condolences to the family of the deceased and continues to monitor the health of those affected.
Health authorities suspect that the outbreak may be linked to contaminated cooling towers in the neighborhood. Dr. Vicky Sheppeard, Public Health Unit Director at SESLHD, explained that Legionnaires’ disease can occur when water particles contaminated with Legionella bacteria are emitted into the air and subsequently inhaled. While no source has been definitively confirmed, the district has twice ordered building owners to disinfect their cooling systems since the investigation began in June.
Residents and anyone who has visited Potts Point recently are urged by health officials to remain vigilant for symptoms such as fever, chills, cough, and shortness of breath. These symptoms can develop up to 10 days after exposure and may lead to severe pneumonia, especially in older individuals or those with underlying health conditions. Legionnaires’ disease is not spread from person to person but is contracted through inhalation of contaminated water droplets, typically from poorly maintained cooling systems.
The SESLHD and the City of Sydney are continuing to inspect and test all potential sources of contamination in the area, encouraging building owners to comply strictly with maintenance regulations under the NSW Public Health Regulation 2022. Authorities emphasize the importance of prompt medical attention for anyone experiencing symptoms who has recently spent time in Potts Point.
“The District has requested building owners disinfect their cooling towers on two occasions since the investigation began in June,” said Dr. Sheppeard. “People who have recently been in Potts Point and develop these symptoms should see their GP or go to a hospital emergency department”.
