Mr IRONS (Swan) (14:21): My question is to the Treasurer. It is without notice, so he will not know this question is coming. The SPEAKER: Then maybe the colleagues of the member for Swan will allow him to be heard in silence so that I can hear the question. Mr IRONS: I remind the Treasurer of his statement on 25 March 2011 in which he said: Revenue from the MRRT does go to investment in infrastructure projects like the Gateway project in Western Australia... If we don't have the revenue from the tax then we can't make the investments. Given that the mining tax has raised less than 10 per cent of that promised, how will the government pay for the Gateway project in my electorate of Swan in Western Australia?
