The deaths of two children at the The Children’s Hospital at Westmead in Sydney’s outer west have sent a sharp reminder through the facility services and healthcare cleaning sectors that mould management in clinical environments carries life-or-death consequences. NSW Premier Chris Minns has confirmed both children, cancer patients already navigating compromised immune systems, died with mould infections. Minns has pledged full transparency as investigations get underway.
“I’m devastated for them,” he said in a statement. “It’s obviously terrible and our condolences are with those families.”
The Westmead deaths come on the heels of a deadly mould cluster at Royal Prince Alfred (RPA) Hospital, where three organ transplant patients died after contracting invasive fungal infections linked to construction activity near clinical spaces. Taken together, the two incidents represent a significant and deeply concerning pattern across the NSW public hospital system.
Ageing infrastructure, elevated risk
NSW Health has indicated there is no confirmed link to construction activity at the Children’s Hospital, in contrast to the RPA outbreak. But Health Minister Ryan Park acknowledged the broader challenge of managing infection risk during infrastructure transitions.
“Not all of our hospitals are brand spanking new,” Park said. “We’re transitioning to the new at the moment.”
For cleaning and facility services professionals, that transition period is precisely where risk concentrates. Ageing buildings are more susceptible to moisture ingress, compromised ventilation and the conditions that allow mould spores to proliferate. When those environments also house immunocompromised patients, transplant recipients, cancer patients on chemotherapy and premature infants, the margin for error collapses to near zero.
Shadow Health Minister Sarah Mitchell went further, suggesting the issues had been known and inadequately disclosed. “I think there’s been a cover-up,” she said. “I think the community deserves better.”
What the industry needs to hear
Whether or not the investigation confirms systemic failures, the episodes highlight a critical message for anyone delivering cleaning, hygiene or facilities management services in healthcare settings: infection prevention is a whole-building discipline, requiring proactive mould monitoring, rigorous moisture management and clearly defined escalation protocols when remediation is needed.
The RPA and Westmead cases underscore that vulnerable patients cannot wait for reactive responses. Facilities teams need the training, tools and authority to act before mould takes hold – and the industry has both the expertise and the responsibility to help healthcare operators get there.
An inquiry is underway, and Minns has committed to making findings public. The cleaning and hygiene sector will be watching closely.
