I should have put this in a bit more context for you both before posing the question. We had the immigration department in and their comments, when posed a similar question were that it could be huge and that they would have to rethink how they do this because it simply wouldn't be possible to hire enough people, and it wouldn't be a good way of dealing with business. They also said they would have to think of a completely different approach to make sure that everything was out there.
I'm just putting that on the record before perhaps you answer the question, Mr. Holman.
