One always tries to avoid resorting to hyperbole or comparisons linked to extreme events, but in this instance there doesn’t seem to be any choice. So we will be blunt on this particular occasion: if Prime Minister Scott Morrison, Health Minister Greg Hunt or any members of the federal or ‘national’ Cabinets seek to impose a ‘vaccine passport’ that restricts the freedom of movement and liberties of Australians, they will potentially be guilty of human rights abuses and even crimes against humanity.
