Senator BIRMINGHAM (South Australia—Minister for Education and Training) (14:48): I am pleased to see that there is such a highly-thought-through process of questioning there from the Australian Greens, that this is the best we possibly have. Government senators interjecting— Senator BIRMINGHAM: As indeed some of the interjections coming from behind me pointed out, if you want to draw the analogy the first point you would make is that the entire state of Victoria did not face a blackout yesterday. The second point you would make is that in Victoria, of course, this does not come on top of what occurred in South Australia previously, which are the types of price spikes, brownouts and other issues the state has faced over a prolonged period of time. And it does not come in the face of the reality that South Australia has the highest priced, least affordable energy in the country. That, of course, runs in tandem with having an energy market that is dependent upon the highest level of wind energy in the country and the lack of frequency and stability that AEMO have indicated that provides into the energy market in South Australia. The PRESIDENT: Senator Hanson-Young, a final supplementary question.
