Got automated call pretending to be from ATO saying some bullsh*t about my TFN and telling me to press '1' to hear more information.
Once I did that, a man answered. I am 90% he was using some voice-changing software. Asked me about my name (I gave them a fake name) and my TFN. (Should have given them fake TFN as well but) once I told him I don't remember my TFN - he hang-up immediately.
100% money scam or identity scam.
