Senator WATT (Queensland—Minister for Employment and Workplace Relations) (14:46): Well, I've already provided the figure of $122 billion. I'm not across the Bloomberg estimate that you cite, Senator Roberts, and I'm certainly not across the One Nation consensus figure. I assume that's a consensus between you and Senator Hanson—you've had to sort of thrash that one out between the two of you and arrived at a consensus of $1.5 trillion! The PRESIDENT: Senator Roberts? Senator Roberts: I'm happy to answer Senator Watt's question. The PRESIDENT: Perhaps some other time—thank you, Senator Roberts. Senator WATT: Maybe James Ashby was in there as well, with the calculator going, working out a consensus figure. And I certainly don't know what assumptions underpinned the One Nation/James Ashby/Senator Hanson/Senator Roberts consensus figure. But the fact is that the cheapest way that we can meet our power needs into the future—as cited by AEMO and the CSIRO, our most eminent scientific body—is at a cost of $122 billion. That is the cheapest way we can meet our power needs, which I think is a very good reason for any government, no matter what their political party, to pursue it.
