Legionnaires’ Disease Sydney Alert Sparks Concern
A public health alert has been issued following a serious outbreak of Legionnaires’ disease in Sydney’s CBD, with one person confirmed dead and several others hospitalised. NSW Health reported that 12 people who had spent time in the central business district and its surrounding suburbs between March and April contracted the illness, prompting widespread testing and urgent action from authorities.
“Sadly, one of the people who contracted the disease passed away in hospital last week,” a NSW Health spokesperson confirmed.

Legionnaires’ Disease Sydney: Source Under Investigation
More than 165 cooling towers across Sydney were inspected as part of the investigation into the source of the outbreak. NSW Health found legionella bacteria in one of the towers, which is now undergoing decontamination and further testing to determine if it was the origin of the spread.
“Outbreaks sometimes occur when bacteria from environmental sources such as cooling towers atop large buildings become contaminated. It is not spread from person to person,” explained Dr Vicky Sheppeard, Director of the Public Health Unit at South Eastern Sydney Local Health District.
What is Legionnaires’ Disease?
Legionnaires’ disease is a form of pneumonia caused by inhaling water droplets contaminated with Legionella bacteria. The disease is not spread from person to person but can be fatal if not treated quickly. It primarily affects people with weakened immune systems, chronic health conditions, smokers, and those over 50.
The bacteria typically thrive in artificial water systems like cooling towers, spas, hot water tanks, and air conditioning units in large buildings.
Symptoms of Legionnaires’ disease include:
- Fever and chills
- Cough, sometimes producing mucus or blood
- Shortness of breath
- Headaches and muscle aches
- Nausea and diarrhoea
- Confusion in severe cases
Symptoms can appear two to ten days after exposure. NSW Health urges anyone who was in the Sydney CBD during March and April and who experiences these symptoms to seek immediate medical attention.
Sydney’s Legionnaires’ Disease Outbreak: The Human Cost
Of the 12 confirmed cases in Sydney, 11 people have been hospitalised. One additional person received care outside of a hospital setting. According to authorities, many of those affected were in areas such as Pitt Street, George Street, and Town Hall—high-traffic locations frequented by thousands daily.
Dr Sheppeard said, “Most building owners have responded quickly to ensure that their cooling towers are operated and maintained in compliance with the NSW Public Health Regulation 2022.”
The regulations require routine maintenance, testing, and treatment of cooling towers to prevent the growth of harmful bacteria such as Legionella.
Legionnaires’ Disease and Vulnerable Populations
Legionnaires’ disease is particularly dangerous for those with compromised immune systems or underlying health conditions. Those most at risk include:
- Older adults (especially over the age of 50)
- People with chronic lung conditions
- Smokers
- Individuals on immunosuppressive medications
- Cancer and diabetes patients
Legionnaires’ disease Sydney outbreaks have historically occurred in public or commercial buildings where water systems can harbour and disperse the bacteria if not properly maintained. Hospitals, aged care facilities, and shopping centres are often monitored closely due to their vulnerability.
A Preventable Tragedy?
Public health experts say that with proper monitoring, such outbreaks can be prevented. Cooling towers and water systems in large buildings are required to be maintained in line with government regulations. However, as this outbreak shows, even one missed maintenance cycle or failure in decontamination can have deadly consequences.
Carol Bennett, chief executive of the Australian Communications Consumer Action Network (ACCAN), commented, “Unconscionable conduct is a high bar, and one that was spectacularly surpassed in this instance, preying on some of our most vulnerable communities.”
Advice for the Public
Health authorities are urging anyone who was in the Sydney CBD or surrounding suburbs—particularly those with health vulnerabilities—to remain vigilant. NSW Health says that the public should not panic but take symptoms seriously and consult their GP if they feel unwell.
The Public Health Act 2010 and accompanying regulation in New South Wales require routine checks and proper maintenance of systems like cooling towers, air-handling units, and warm water systems. Outbreaks of Legionnaires’ disease Sydney-wide are actively investigated by public health units to limit the spread and protect residents.
A Reminder to Building Owners and Managers
This incident serves as a critical reminder for building owners and facility managers to adhere strictly to maintenance protocols. Regular testing, cleaning, and prompt decontamination of water systems is essential. Legionnaires’ disease outbreaks are not only costly in financial terms but can also cause severe harm—or even death—as shown in this tragic case.
Ongoing Investigations and Future Updates
NSW Health continues to work closely with the City of Sydney and other local authorities to ensure the affected tower is decontaminated and all others are thoroughly reviewed. While the initial findings point to a single cooling tower, investigations are ongoing, and additional towers may still be implicated.
For real-time updates and public health information, residents are encouraged to monitor the NSW Health website and news outlets covering Legionnaires’ disease Sydney developments.
