Claim to be ATO. Tried calling number back 3 times and after 1 ring get a message ‘All circuits are busy’ then hangs up. Got me suspicious as gov body wouldn’t have this type of message, hmmm.

Same as above - left a voice message claiming to be ATO. Had an American accent.

Answered call, claimed to be the Australian Taxation Office. Who knows if this is a scam.
