Via a tweet from iiNet, who were sued by AFACT in the Australian Federal Court, this comment on the case from a US cable released by Wikileaks:

Despite the lead role of AFACT and the inclusion of Australian companies Village Roadshow and the Seven Network, this is an MPAA/American studios production. Mike Ellis, the Singapore-based President for Asia Pacific of the Motion Picture Association, briefed Ambassador on the filing on November 26. Ellis confirmed that MPAA was the mover behind AFACT’s case (AFACT is essentially MPAA’s Australian subcontractor; MPAA/MPA have no independent, formal presence here), acting on behalf of the six American studios involved. MPAA prefers that its leading role not be made public.

It also appears the Australian companies involved needed some persuasion to be involved – I wonder if it involved any of the folding paper/plastic type of persuasion ?

AFACT and MPAA worked hard to get Village Roadshow and the Seven Network to agree to be the public Australian faces on the case to make it clear there are Australian equities at stake, and this isn’t just Hollywood “bullying some poor little Australian ISP.”

They also go into the expected reasons why they picked iiNet – mainly that they weren’t Telstra (they were scared of them).
