Now, what I find interesting, what I really want the Minister to address, is where do these testing requirements come in? Because, as Michael Woodhouse, who was speaking just a second ago, pointed out, the bill very clearly contemplates that some people who are required to do work will be able to meet the criteria by being vaccinated or tested. And this is not only important in the context of the bill, which contemplates vax-or-test, it's important in the context of the response to COVID-19 globally. Because, in quite a number of different theatres the requirement is to be either vaccinated or tested, not just vaccinated. And once you think about that, you have to start asking, well, what is the purpose of this piece of legislation?
