The answer to that is both of the above. As I mentioned, there are a large number of proposals currently on the table, because business is able to see that there is going to be a capacity constraint. I would say that this will be within the next four or five years, and I think it will more likely be within the next two or three years. Then some of these projects will come on stream, and if all goes well and the environmental assessment works out and so on, I think capacity will then likely be adequate.
Without necessarily wanting to promote one company rather than another or one project rather than another, I'll just mention a few things that are being proposed.
