Very much ASB:
- In an effort to stem the 'Emu Menace' Australian biologists develop & unleash a tailored disease which does initially reduce the population but the survivors are now carnivorous, near indestructible creatures which can lay up to 50 eggs a year. The new super-emus soon consume most of the cattle & sheep of the interior and begin to move into the cities in search of fresh prey. The last survivors evacuate to Tasmania leaving the continent to its new masters.
