NSW Health still trying to find the cause of the outbreak

Inside the hunt for the northern beaches' elusive patient zero
Three mystery cases of the same strain of COVID-19 that erupted within hours of each other at opposite ends of Sydney’s northern beaches are at the centre of the hunt for the outbreak’s patient zero.
However, the popular theory that Sydney’s latest wave of cases was spawned by a celebrity or a business identity self-isolating on the beaches’ affluent northern peninsula appears to have been debunked by authorities.
Authorities remain at a loss as to where the quarantine system broke down, allowing the virus to seed across the northern beaches, trigger devastating Christmas lockdowns and jumping borders into other states.
“The source of the Avalon cluster remains under investigation,” a NSW Health spokeswoman said.
There are still 13 mystery cases that have not been linked to a transmission source in NSW.
A month after the northern beaches cluster plunged Sydney back into lockdown, here's everything we know about patient zero.
