Senator SINODINOS (New South Wales) (14:20): Mr President, I ask a supplementary question. Does the government agree with the modelling conducted by PricewaterhouseCoopers reported in today's Financial Review which reveals that the iron ore price would have to go up from its current price of around US$120 to US$140 a tonne for the mining tax to raise any revenue? Does that mean the government expects iron ore prices to rise to over $140 a tonne for the remainder of this financial year?
