So in terms of terminal gate price, you know, I think a lot of people will support that idea, and visibility around that may be helpful. But it's going to be interesting to see what that is going to do to prices, because in the conversations I've had with chief executives in the energy sector, in the liquid fuel energy sector, they have said, "Well, that's happened in Australia, but we haven't seen the effect come through in the market price." So we can tinker, we can change, we can put different mechanisms in place, but the answer to all of this in terms of getting better pricing is having better competition. You've got to find the balance between having the right level of margin in terms of getting people into the market, and you've got to have people going in there who can get their slice of that market, and that's what we've seen with the independents. We've seen a huge increase of those independent retailers over the last five years, so much so that many actually say that we do have a healthy, competitive market.
