Australian Citizenship Practice Exam

Australia established its system of government through the Australian Constitution and federation in 1901. This option is correct because it accurately reflects the process by which Australia became a self-governing nation. Options A and B (through a revolution or military coup) are incorrect because Australia peacefully achieved its independence from British rule. Option D (through a monarchy imposed by a foreign power) is also incorrect because while Australia is a constitutional monarchy with the British monarch as the head of state, it is not considered a foreign power.
