this number left threatening legal action and a warrant for arrest relating to ATO; did not reference any one person and has rang out all day

These aresoles left the same typical message on my answering m/c, he had a good indian accent.

See https://www.scamwatch.gov.au/news/telephone-calls-alleging-fake-arrest-warrants-used-to-scam-money. Was asked to call them back on (08) 6193 8011 which of course I did not and don't recommend anyone does.

And the number they have left doesn't answer.

Also left threatening legal action relating to tax... no names, reference etc.

We got the same message they rang twice a day for two days

Yop got the same thing today, just rubbish.

I had the same threatening legal action - who do you report this number?, No doubt it is a scam.

Per previous. Left message stating that legal action was about to be taken in relation to ATO matter

I got this call twice today.
No ref, no mention of my name.
He claimed to work for CDPP
