I doubt it. That ruling applies to privacy restrictions relating to fostered children.
However, as I've said here before, the more nefarious this pair becomes with their numerous court cases, the more likely IMO that more and more places on the Web will start naming them, especially outside of Oz.
As I understand it the privacy on their names is no longer about them being foster parents but because of threats against their lives. I seem to recall a judge saying something along the lines of that.
