But there are other questions I had about the legislation too, about the cost of that database. This is going to be a huge cost, especially the platform that it's going to be maintained on. So that cost, of course, is going to fall back on the users of that, who are the people who are coming in to have their campervans certified. But the other point that has been made tonight—and it's very relevant—is that it's all very well if you've got a $100,000 or $200,000 motorhome and you can have a fully plumbed-in toilet, but there is another cohort in this country, and that's mum and dad and the kids, who want to get out and have their camping holiday. They're using a very small porta-potty—that is, a chemical toilet—that is as healthy as any other that you will have, except it's containment is right there, rather than plumbed in under the vehicle. That's completely suitable and it's completely safe and sanitary, but that's going to be excluded from this bill.
