It is important for us, here in Australia, to make sure we do not confuse the issue of evaluating these various proposals with the desirability of being present at the table when these discussions take place. Whatever the merits of particular arrangements, these discussions are, in themselves, an important part of the process of swapping ideas and coming to understand each other better.
So the case for Australia wanting to be there is a clear one, and we should state this clearly (as we have done), without wishing to elbow our way into any arrangement in which we are not wanted.
