Would you support an Australian Republic and a new constitution?

I agree to most said here, though I am a long way off having a complete model.
Yes to cutting all ties to the British Monarchy except in our history, something we should start teaching again.
Yes to getting rid of the Westminster system, it is based on a society we have never had here really.
Keep our head as The Governor General of Australia, that is what he is. It is what we know, but he should be given new teeth and roles that extend to a lot of those currently under those of the Prime Minister, especially in International Relations. The Governor General is the Commander in Chief of the Australian Armed Forces, he should be the one discussing things with his counterpart, the Commander in Chief of the US Armed Forces, the President of the United States of America.
We should be governed by the collective governance, no Prime Minister, multi-party is fine, but maybe a little less power to parties after the election.

Referendums to challenge changes in law and initiatives to amend the constitution. The Sovereign of Australia should be it's entire electorate.

We need more, smaller, more specifically designed states. Not a lot, definitely not 50 odd we don't have the population, but NSW should be 3 states and Queensland 3 also I believe although a lot more investigation needed here, then if we do that, I would agree to proportional representation.

States would be semi-sovereign states in all aspects except international relations, law, health, education and transport. These are federal responsibilities because they all really either traverse state boundaries of we need a national standard. This would allow the Federal government to be reduced to a Federal Council heading the Federal Administration.

We should have a Unicameral Legislature, the Senate, made up from equal members from each state, bills submitted would be either state or federal, if the senate agrees that a bill is truly only a state act, then only that state will vote.

Bills could be proposed by the Federal Council, senators or any registered voter (with conditions).

All very rough yet.

 

You probably don't need states as such other than to define geography. You could have super councils that are overseen by perhaps a state governor or a type of state administry. That way everything would become uniform, ie. Education, health, etc.

Big job..... But a tad exciting the whole notion.
