I'll give you an example as a local MP that, Mr Speaker, I'm sure will be familiar to you. During the measles outbreak last year, I had a principal get in touch and say, "Look, you're my local MP, I need your help. I've got students at my school who refuse to be vaccinated for measles. I've got other students who, for medical reasons, cannot be vaccinated for measles. Under the Health and Safety at Work Act, I'm a person conducting a business or undertaking (PCBU). If I let those people who won't come to school and potentially infect those who can't, what is my liability, and should I have the right to insist that if students want to come on to the premise that I as a PCBU am responsible for, they be vaccinated?" We've already had a rehearsal of that, and there are no doubt going to be many further clashes of rights as it goes on.
