Voting Libs because an over-saturation of Labor is a recipe for disaster.
@kingpomba - The concept of having the nation divided into states is a Federalist ideal, connected to the liberal theory, which is enacted to ensure that not all power is held in the hands of the one government or leader. It also has other benefits, including the ability to move between states should you dislike policy in one or the other (more choice for the citizen) and competition between states to provide the best facilities to their citizens. Because States often divide up very geographically different land, it is more efficient to have States than just one main government. Imagine trying to govern the NT and Victoria under the same State rules - it just likely wouldn't work very well because Victoria has highly populated metropolitan and suburban areas while the NT has some metropolitan but many rural areas as well as a higher concentration of the indigenous population. People wouldn't be happy to live under the same conditions of government.
You can note that most countries with states or provinces are very large, like our own. America has preserved its federalist traditions because yes, it is conservative by nature and favours the liberal ideology. But you can also see that different areas would have different needs there, much as they do here. Most countries that choose to abolish Federalism are smaller than what we/the US are. Each State has different needs and a side effect of Federalism is the ability to address those different needs. In theory...
Also, just to add, abolishing the states would be extremely difficult because the idea of state divisions is deeply ingrained in the Constitution, whose main role in Australia is to maintain federalism and keep power where it should be (ie, granting some powers to the states and some to the Fed government). Considering Australia rejects pretty much every referendum it sees (see, republic, etc.) there would be public uproar if you tried to amend that much of the Constitution, and it would never work.
Most of your facilities are delivered by the States anyway - I don't know why you would want to direct all systems of health care, public transport, education to one currently very unstable Federal government.
