**Australian National Flag** (Blue Ensign + Commonwealth Star + Southern Cross) represents the Commonwealth; flies above state flags on federal buildings.
All state flags follow **colonial Blue Ensign template** — unique among federations (Canada's provinces have distinct designs; US states vary widely). Reflects Australia's evolutionary path to nationhood.
State flags fly at parliament houses, schools, courts, and by citizens expressing state pride.
