I understand that. Maybe I should interrupt. It was a simple question, and I think you've given the answer that you do indeed regard them as reasonable.
It was a kind of trick question, in a way, because the provision for quarantine regulations under the Quarantine Act says that you can't undertake certain measures unless there's no reasonable alternative.
I'm comparing the measures for the land border measures with the air travel measures, particularly with respect to the hotel quarantine. There's no reasonable alternative to the hotel quarantine, I would have to assume.
If I ask you that, then I will ask you the following question. How is it, then, that it's possible—and we've heard a number of MPs talk about this in the last number of days—for people to bypass this by landing in the U.S. and then taking a bus across the border and all of that? How is it that it's a reasonable alternative to have a land border without a hotel quarantine, but it's not in the case of air travel?
