They are, in essence, the immigration and customs border services. They work hand in hand with the Australian foreign intelligence service, ASIO. They're working with the administrative components for Australia, but their focus is very much preventative and looking abroad. They have officers who are abroad. It's a good model. It's more prevention-focused as opposed to reactive. I think it's a very good model.
Now, as with anything, I'm not saying that all aspects of the Australian system are great, but they do have some components that I think are great.
