Cute. Let's see the reviews for an existing Australian government auth app: https://play.google.com/store/apps/details?id=au.gov.mygov.m...
And the kicker is that the above app doesn't even need to exist since myGov could just use industry standard TOTP two-factor auth like the dozens of other services I use.
Aussie politicians once again conforming to their lucky country stereotype:
"Australia is a lucky country run mainly by second rate people who share its luck. It lives on other people's ideas, and, although its ordinary people are adaptable, most of its leaders (in all fields) so lack curiosity about the events that surround them that they are often taken by surprise."
