Authorities are investigating claims the so-called Islamic State (IS) has published information about Australian officials, urging attacks on them.
A group claiming links to IS had allegedly obtained and published online data mostly about US defence officials.
The Australian government has confirmed at least eight Australians are on the list, including an MP. Justice Minister Michael Keenan said intelligence agencies were looking into the threats.
He said the list contained up to 1500 individuals including “at least eight Australians”, he said on Thursday.
“If there was any threat to any Australians’ physical security then obviously we would take the appropriate action to make sure that people are safe,” Mr Keenan said.
