Colonialism
Scientific racism is rampant in Australia. Our fair nation has suffered the woes of physical anthropology for too long. Biology has manipulated the method of polotics.
In Australia the project of colonisation has ceased mid-flight. There is the dead foetus of the abortion of the replication of the privileged class.
We from the colonies have cultural sub-terrain vengeance toward our ancestors. Where were we when the loot came home?
Build the bunker and then send out the bunker building instructions. The colony spreads.
The indigenous people of Australia were able to survive for thousands of generations eventually arriving to a symbiotic existence saturated with dance, song and ceremony.
