Purports to be from the Aust Tax Office.... claims my house is under surveillance (couldn't pronounce it) and I am wanted for a crime.
Rang the ATO who said to log it online which I will.

Yes i got the same saying ATO investigation so be careful if you got the phone call from this number don't give them your details

Claims to be from the Australian Tax Office and that there's an affidavid lodged against me, and that house is under surveillance. Phonecall location on Iphone showed up that the call was coming from Yass, NSW. Blocked the number.

Caller claims to be from the ATO

Got a Robo Call at 8.47am in the morning; as soon as i heard it i disconnected and blocked the number.

appears to be scam, a Google search brought up that the people calling from this number pretended to be from the ATO to gain personal information.

these scammers have a pre recorded message claiming to be the ATO- they claim your under investigation and that they will represent you legally- complete BS
