9.1.2. Nature of the Constitution

Like the United States, Australia has a written constitution. The Australian Constitution defines the responsibilities of the federal government, which include foreign relations, trade, defence and immigration. Governments of the States and territories are responsible for all matters not assigned to the Commonwealth, and they too adhere to the principles of responsible

government. In the States, the Queen is represented by a Governor for each State.

The High Court of Australia arbitrates on disputes between the Commonwealth and the states. Many of the court’s decisions have expanded the constitutional powers and responsibilities of the federal government.
