Apparently I am in violation of tax law and to prevent a warrant for my arrest being issued, I need to talk to them urgently (presumably to give these scammers the $$ rather than the tax commissioner)

To the above commenter - the actual ATO has a warning about these scam callers on their website https://www.ato.gov.au/general/online-services/identity-security/scam-alerts/#Sep2018phonescamfaketaxagent

Afterhours voicemail in English accent threatened me that a warrant was out for my arrest and I needed to call this number to resolve ??? with a payment. I blocked immediately.

I got the same voicemail message as the above - super low even for a scammer. I blocked immediately.

Said I am in violation of tax law and there is a warrant for my arrest. Definitely a scam as I am underage and do not get taxed.

I got the same phone call today

Spam message for scammer claiming to be from ATO

Yep I'm in violation too! Funny no name/address or Tax Office mentioned in the voice mail message left! SCAM

i got the same call asking for the same things you mentioned, is this confirmed a scam?
