Senator BABET (Victoria—United Australia Party Whip) (14:47): Minister, you said it would not be compulsory, and I hope that is right, but the COVID-19 vaccine was not compulsory either, and look what happened there. Take it or you don't get a job, right? What guarantee do we have from your government that this will be 100 per cent not compulsory? Will you write it into the legislation itself, in black and white: this is not compulsory, forever and always, the end?
