Australia operates under a federal parliamentary constitutional monarchy political structure. The country is a federal state composed of six states and two mainland territories, with the Queen of Australia as the constitutional monarch and the head of state. The monarch’s role is largely ceremonial, and executive power is exercised by the Prime Minister, who is the head of government. The Prime Minister is the leader of the majority party or coalition in the Australian Parliament and is responsible for leading the government and implementing policies.

The Australian Parliament is a bicameral legislature, consisting of the House of Representatives and the Senate. Members of the House of Representatives, also known as Members of Parliament (MPs), are elected through a preferential voting system from electoral divisions across the country. The Senate comprises Senators who represent each state and territory. The Parliament is responsible for making laws, approving the national budget, and providing oversight of the government’s activities. Australia also has an independent judiciary that operates separately from the legislative and executive branches. The judiciary is responsible for interpreting and applying the law, resolving disputes, and upholding the principles of justice. The High Court of Australia is the highest judicial authority in the country and plays a crucial role in ensuring the constitutionality of laws and safeguarding individual rights.

The political structure in Australia upholds democratic principles, including the separation of powers, the rule of law, and the protection of individual rights and freedoms. The combination of a constitutional monarchy, a parliamentary system, and an independent judiciary helps ensure accountable governance and democratic decision-making processes in the country.
