Australia does not require local stage three testing for medicines for what should be obvious reasons. That’s what peer reviewed science is for, and federal approvals in the jurisdictions of invention. Just like aircraft type certificates haven't been (pre-max) second guessed for 25 or so years now.
Already a number of African countries require a Yellow Fever vaccination card before allowing entry into their country. This will just extend with Covid. Countries will not permit entry of non-vaccinated travelers which will need to be supported by a vaccination card or passport stamp and insurance companies will refuse to cover them. You can be an anti-vaxxer but you'd better be one that doesn't want to travel.
