Full breakdown
Government & politics
Australia
Australia combines a Westminster parliamentary system with a US-style elected Senate and a written federal constitution. The monarch is head of state, represented by the Governor-General, but power rests with the Prime Minister and Cabinet, drawn from the elected House of Representatives. Unusually, the Senate is powerful and fully elected, and the High Court can strike down laws that breach the constitution. Voting is compulsory.
New Zealand
New Zealand is a constitutional monarchy with an uncodified constitution, similar to the UK. The monarch is head of state, represented by the Governor-General, but power rests with the Prime Minister and Cabinet. Its single-chamber Parliament is elected by mixed-member proportional representation (MMP), which usually produces coalition or minority governments.
