Oh boy! I'm flying overseas soon for the first time in about 7 or 8 years. Does this imply they have backscatter and there's no alternative? I'm guessing this is at every international airport?

I see it's random? Sorry I'd rather ask somebody who's been there then misread the carefully crafted Q&A.

I don't understand the Australian impulse to push this technology when they are under a very low if not non-existent threat. When I was there I was 'wanded' multiple times.

I tend to think they were strong-armed into it.
