Hon DAVID PARKER: I am not yet in a position to judge that. We have had some difficulties getting cooperation from the smelter in respect of these matters, although at the latest meeting that we had with the new chief executive of Rio Tinto smelters in Australasia—a meeting at which the Deputy Prime Minister, the Minister of Energy and Resources, and myself were present by Zoom—there was a noticeable change of tone from the smelter, and one of the things they said was that they intend to remove all of the concrete cathode linings and take proper responsibility for them.
