Isnt that standard procedure in Australia? I watched a few Border Security: Australia's Front Line episodes and I remember seeing them take someones phone and text/call few listed contacts pretending to be the user. Australian border as a whole is very communist Russia/East Berlin like, papers, where are ze nuts? who do you know? why do you come here to terk urr jerbs? and obligatory 'are you a criminal?', as if they still only let criminals in (btw they really dont like this joke).
