But (more) seriously.....you have to have a two pronged approach. One, using your "band-aid" approach to provide some sort of deterrent for idiots...and two, secret squirrel, back room, cloak and dagger stuff...to weed out the nasty, intelligent ones. We don't hear much about the number twos, as we don't need to...but it's certainly going on.
Peuce, you have said the “number twos” are smart so you can be sure they are not travelling under their own identity and as there is no ID checks there is no way they can be monitored. The only way is facial recognition or AI, maybe both.
Australia still has its head in the sand regarding security, we still have to hope we never have a major event here as security is just theatre for the masses.
