I called back number (08) 9468 8974 rang once then gets disconnected automatically.

Caller: Scam no about tax

Seems to be tax fraud
Saying you owe money
Recorded message

Caller: SCAMMERS with a very serious deep American voice.

Apparently If I don't call another number immediately a warrant with my name on it [ha can't even use my name] will be issued for my arrest. Must be serious normally I thought a cop came to your door without prior warning guess as they don't know who I am or where I live I may just have to leave the country.

Left message threatening to issue arrest warrant if the call is not returned. Sounds like a computer voice

claims to be from ATO audit etc. Automated voice it sounds like and kind of threatening in tone. And phone number is in Perth.

Caller: Some guy with American accent

Saying there was an arrest warrant out for outstanding tax debt and to call back on this number
