A recorded robotic voice claimed there was a federal police arrest warrant for me for tax reasons. Voice said that on receipt of the message I had to press 1 immediately.
I didn't press 1.
Listened for a while without saying anything but good morning (never say yes to a phishing phone call) and then hung up.
COME AND GET ME COPPERS!

Caller: Australian taxation office recorded message

Hung up as soon as they said tax office.
