The Internet Industry Association (IIA) sought leave to appear as amicus curiae in these proceedings, to the extent of making oral and written submission.

Leave was denied. Cowdrey J held that the IIA’s contribution was not “useful and different” from the contribution otherwise given by the parties, saying that the mere fact that the IIA is not iiNet, and thus claims to bring a “broader perspective” does not render its submissions “useful and different”.
