Dunno about this situation, but there's a discussion in http://www.austlii.edu.au/cgi-bin/sinodisp/au/cases/cth/FCA/2010/24.html http://www.austlii.edu.au/cgi-bin/sinodisp/au/cases/cth/FCA/... starting at about paragraph 110. They are coy about the details, I suppose to make circumvention harder or something.
