Operating rooms were closed at Fiona Stanley Hospital in Perth and ambulances diverted after flooding at the $2 billion health facility, according to an article on the ABC website.
Sections of the hospital were previously flooded in April when a water pipe burst, forcing the closure of eight operating rooms.
That incident led to the cancellation of some surgeries and affected hot water and air-conditioning systems in the hospital.
Fiona Stanley Hospital cost $2 billion to build, but structural problems continue to affect operations, the article said.
Since the hospital opened, it has been plagued by a number of issues including surgical equipment not being properly sterilised, medical consultants quitting because of excessive workloads, and concerns about the delivery of intravenous drips and other medical supplies to wards.
