It should be your top priority to find a pure blood woman, unfortunately 99.99% of the women who are not vaxxed in Australia are already married to a strong man so I don't envy you mate.
If you want to have kids you should seriously consider relocating to a different country as Australia is the most vaxxed nation on earth, but then again women overseas could just lie about their vaxxed status unless they're in a strong faithful family.
Russia vaxxed their people with a non mRNA vaccine so that's maybe your best bet.
