Didn't answer. Phishing attempt. How do I know? They called twice within a few hours, and left the identical message from two different numbers. The recording claims to connect the callee to their "Australian Border Force agent," mentions a package that contains "illicit" materials, and demands pressing 1. The other number they called from is 0432 741 389.
I see that it's already making the rounds: https://www.9news.com.au/national/messaging-scam-pretending-to-be-abf/f5f9dda6-3679-4ebc-87ca-9c9bcabef454
