I got the same 2 calls as well but the number differed from mine with some different numbers. They said the same exact thing.

Spam call purportedly from 0438 720 226. Suspicious as this number differs from my own number by just one digit.
This call, at 4:23pm CST on 26 July 2021, was identical to one received from 0485 970 186 at 3:03pm CST the same day.
Clearly articulated recorded message with a credible professional-sounding male voice, stating he was from the National Crime Authority. He claimed that there were irregularities in my banking and that my accounts had been suspended. Warned that I was in danger of being arrested. Advised me to press 1 to obtain advice on my options to avoid being arrested. Repeated with some urgency that I should press 1 now.
