It will likely be effective. That’s not the point I was making. I’m pointing out that in most western democracies there would be legal challenges and a massive outcry if such a ban was instituted (there were/are no-fly lists in the US but those are ostensibly aimed at preventing terrorism, they aren’t meant as administrative punishment for unrelated offences). The few complaints I’ve seen about the policy are that tax cheats and multinationals aren’t subject to the same ban, not anything from a civil liberties perspective about the wrongness of such a policy per se. On the flip side, it’s possible that locking them up would be politically unpalatable, so this a better alternative..but again that would give the concept of “rule of law” short shrift. Australians are more accepting of government authority than people in other western especially “Anglosphere” democracies.
