If you bring a suitcase full of bananas in to Australia, customs will take them and detroy them, and probably prosecute you.

If you bring an electronic device in to Australia full of 0s and 1s that can be decoded to display as pictures of bananas, customs will just think your a bananaphile and shuffle you along.

Digital goods are fundamentally different.

You can’t cross the border, buy a suitcase, then download a bunch of bananas to fill it.

You can cross the border, buy a phone, then download instructions from your terrorist boss.

Whatever else these digital searches are I don’t know, but they’re certainly ham fisted to the point of embarrassment for the agents and agencies.
