I was called by this number. Returned their call. It rang and then before it answered they terminated the call.

Caller: Machine Voice

also scam claiming there is an arrest warrant being issued unless I call back

Caller: Left voice to text message

I called this number back and a guy clearly in a call centre environment (not the usual govt pre-recorded press 1 for this and press 2 for that). He said around 7 words ending with 'tax office'. I asked him to repeat what business it was and he said ATO, THEN "IF YOU GIVE ME YOUR NAME I CAN HELP YOU".

As I'd received my tax refund months ago I told him to send any information to my postal address. Then hung up.

Left an SMS message saying they have two arrest warrants under my name and urging me to get back to them as soon as possible. I have blocked this caller.
