Coober Pedy Underground Settlement is strongest on Population Capacity 9/10 — A functioning town of roughly 2,000 people with housing, health services, education, shops and utility systems has exceptional functional headroom relative to a twenty-person survivor reference group.. Its clearest scored constraint is Defensibility 2/10 — Coober Pedy is a distributed town without a continuous defended perimeter. Individual underground dugouts provide unusually robust secureable shelter, but twenty people cannot defend the whole canonical settlement as one compound and ordinary roads/service areas create many breach points. Remoteness is deliberately excluded from this score..
