I rang back and was told by a person with a foreign accent that I had called the office of Brian Cooper from the ATO. The background noise sounded like a call centre. I hung up.

Caller: Scammer

This is a scam caller, with the exact scam first appearing back in 2019.
They left the exact following (includes spelling and grammar issues) voicemail
"We regretted to inform you that we identified incorrect tax filing. We regretted to inform you that your account has marked lean for tax avoidation. Paperwork to send to registered address has also returned back unsigned and undelivered. For this the petition needs to get filed, including your warrant for arrest now before the case is sent for execution and to receive legal notification. For more information, press one, or give us a call back on same number as this issue is very time sensitive."
