Automated voicemail stated: 'This is the National Crime Authority, Legal Dept of Australia. There has been suspicious activity on your bank account and your Tax ID Number has been suspended. A file case under your name has been lodged at the Federal Claim Court House. Before you are arrested, please press 1 to speak to an operator'. After a brief Google search I discovered that this message is being used as a scam. However this number didn't appear as such on Reverse Australia so I have added it in case it happens to someone else.
