Australia' is a an island country in the Pacific Ocean.
Australia, as an island, will take time to be affected by the virus causing zombiefication (if Australia was not the starting point of the virus). Bush country would prove to be the safest, as it is away from densely populated areas. However, some zombies can walk on the ocean floor, which could become deadly. However, since it's border protection is powerful, and equipped with sonar, 'swimmers' will be terminated before arriving at shore, which only leaves infection through air travel.
- There are not many known cases of Australia having zombies.
