Earlier quoted context omitted.
Any Australian with a driver's license or passport most definitely has their facial biometrics stored. Any visitor to the country also is subject to it. This has been in existence for over a decade and I'm astonished people aren't aware of that.
Right, I do know that (The Capability(tm)!) and for some reason I just mentally exclude facial recognition from the term "biometrics". OP specifically said "at least fingerprints" - it's good to have a reminder that facial biometrics still count as biometrics too, and they're lower on the hierarchy than fingerprints.
Have no idea whether foreigners have to give fingerprint scans at Australian customs, it's common practice throughout Asia.
