Everyone entering Australia to have biometric data scanned (Australia Forum)

A $700 million update to Australia’s border management system will mean that everyone entering the country will have their data scanned and matched against a biometrics database.

Australia is well suited to give this a good chance of working. You can't drive there, or walk there, and their stringent agricultural controls and efforts to keep rabies out means that they're already used to being pretty careful at points of entry.
