The Honourable Minister Dutton is no longer dealing with such matters.
It would be possible to lodge a FoI request to ascertain how many young (and not so young) women have been 'turned back' for looking as if they might have intended to work. And not only women - there was classic case in Darwin years ago where a deaf man was interviewed by telephone and cancelled because he was carrying some pots and pans; his tools of trade. All he wanted to do was visit his family and show them what he knew. He won a review appeal, so the honourable, the minister, invested a good lump of taxpayers' money on a court appeal, and lost it again.
