Hon Dr DAVID CLARK: Thank you, Madam Chair. I think the context of the current situation is important, and I also want to directly address the member's concern about the market study—the first of its kind—funded by the current Government to really get into competition issues in the sector. There has been a documented reduction in the fuel margins charged since the time that that study was released. We can now have a transparent view of those markets, and over the, roughly, 18 months since that report was released, we can see that fuel margins have reduced sufficiently so that the average family filling up a car every two weeks, which is pretty typical, would have saved around $100 per annum as a result of fuel margins dropping. So I would say that that does amount to something that has greater transparency in the market and some evidence that fuel margins have dropped as a response to the findings of that study.
