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.

From my experience going from clean shaven to a small beard can throw the whole system off and requires manual intervention rather than going through the automatic gates. Fingerprints surely would be more accurate.

Have no idea whether foreigners have to give fingerprint scans at Australian customs, it's common practice throughout Asia.
