Strongholds: The Safety Dome
The Australian government had more time than any other when the dead started rising up and eating the living. Since the Zombie Rising started in the northern hemisphere (Kyrgyzstan), Australia had time to stop all air and sea travel into the country and prepare for the worst.
By the time the zombie plague hit the country, they had managed to build the largest structure in human history, the Safety Dome. A mile across and a quarter of a mile high, the dome is made of a steel frame, carbon fiber netting and thick tempered glass. Outside the wall is a ½ mile wide circle of concrete with regularly spaced gun turrets that stand 30 feet tall and are entered only by underground tunnels from the dome. The turrets have machine guns and flamethrowers. The very top of the dome has a heliport and three helicopters. Two of these are military gunships, while the third is a large transport vehicle.
No zombie has ever made it even halfway across the concrete.
Inside the dome, the 10,000 residents live both above ground in two apartment towers and underground, where pretty much everything else is. Most of the surface area is given over to growing food and food animals. Deep wells bring in plenty of water. Life is not bad in the dome, once you accept the fact that you can never leave.
See, in the rest of the world, the humans that survived hid deep underground in government survival facilities designed during the late Cold War period. They sealed themselves in and the zombies cannot sense them. But the Dome does vent air to the outside and that air has the smell of humans in it. Apparently, zombies can pick that smell up even over thousands of miles, because waves of zombies are still coming ashore (nothing eats zombies, including sharks) and heading for the Dome. True, half of those zombies fall apart before they ever get to Australia (because zombies that don’t eat regularly start to decay), but enough get to the Dome to keep the gun turrets and choppers busy every few days. Additionally, the zombie virus lingers until the last scrap of zombie flesh has rotted away.
So the domies go about life awaiting the day (about 3 to 5 years from now) when the last zombies finally die off, at which point they are going to wait 20 more years before going outside to explore. If the zombies and the virus are gone, then they’ll leave the Dome. If not, it’s back inside for another 40 or 50 years.
