Mr President, I ask a further supplementary question. Further to undertaking to take the previous question on notice, will the minister now undertake to table the modelling from which the 49.4 million tonne calculation has been derived? If she is shaking her head, the rationale for the question is that I think the Senate cannot be expected to approve such significant expenditure if it is clear that there has not been even the slightest rigorous debate of the merits or otherwise of this package, even at cabinet level.
