Australia being the last safe haven in a World War Z scenario would be both a blessing and a curse. On the positive side, as mentioned before, its isolation could be a great defense. But on the negative side, it might not have all the technological resources needed to find a long - term solution to the zombie problem. It would have to rely on the skills and knowledge of the people who made it there. There could be a lot of internal politics too, as different regions of Australia might want to handle the situation differently. And what about the Aboriginal communities? How would they be involved in this new world order?
Well, Australia has some geographical advantages. It's an island continent, which means it could potentially control who and what enters. In a World War Z situation, it could use its navy to keep the undead at bay. Also, Australia has a lot of wide - open spaces and natural resources. So, it could be self - sufficient in terms of food production. Maybe they'd set up huge quarantine zones along the coasts.
If Australia were the last safe haven, it would face many challenges. One is population control. With refugees from all over the world trying to get in, they'd have to be very strict about who they let in. They might also need to develop new military strategies to deal with the undead hordes that could potentially wash up on their shores. And there would be the issue of how to maintain order within the country, as different groups of survivors would have different needs and wants.
