I didn't answer so it went to Voicemail. When I checked later it was a recorded message claiming to be from ANZ advising of a suspicious transaction; press 1 to authorise and 2 to dispute (or maybe the other way around).
To my knowledge this is not how ANZ check with account holders for potentially suspicious transactions.
Checked my account a day later and nothing of concern. Don't know what happens if you press 1 or 2 in real time.
