I always think, when there's a bill like this, that it's really important to try and relate it back to your own electorate, because that makes it much more real. So I look to South Port, our wonderful South Port, in that fabulous port settlement of Bluff. If ever you needed a reason for why we should be careful of the impact of shipping emissions on the human environment in and around ports, then Bluff would be it, because, of course, Bluff has a number of amazing things, not the least being the oyster, the Bluff oyster, and the oyster beds that are out in the strait not far from the port there. So, certainly, that's a very good reason to ensure that there's protection from pollution of shipping.
