Three Level of Government in Australia

In Australia, there are three level of governments, the federal government, state governments and local governments. All of these levels of government are necessary. This is so for a number of reasons.

First, the federal government is necessary for the big things. They keep the economy in order and look after things like defense. Similarly, the state governments look after the middle sized things. For example, they look after law and order, preventing things like vandalism in schools. Finally, local governments look after the small things. They look after things like collecting rubbish, otherwise everyone would have diseases.

Thus, for the reasons above we can conclude that the three level governments is necessary.
