Pre-recorded message was stating I had suspicious activity on my bank accounts, they were part of a national criminal justice thing, and to press 1 to speak to their lawyers and to make a payment if I don't want to be charged. Claimed they were with services australia, and that they had my tax identity. Absolute baloney. Fairly certain that if Services Australia or the ATO was calling me, it'd be from a private number. Don't trust them, and call the actual department to confirm legitimacy if you get one of these messages.
