"What is the purpose and benefit of having State Governments?"

The Australian Constitution divides the power to make laws in Australia between the state/territory parliaments and the Australian Parliament.

State/territory parliaments are responsible for matters that affect people who live in that state or territory, such as hospitals, police and roads. The Australian Parliament makes laws about matters that affect all Australians, such as foreign affairs, defence and Medicare.
