For my debate, I have to argue in favour of Australia being a republic. I'm planning on one of my points being that by still being a monarchy, Australia is missing out on multiple international relations which are only for republics, like the USA. However, I'm not sure how to proceed with this. Some international relationships I think I could talk about are:
1. Free trade agreements
Currently, Australia has 10 FTAs in force. Republics like the USA and China have many more, however is it because of their republican status? Also, are there any free trade agreements that only involve republics?
2. Trade Routes Specific to Republics
Are there any goods trading between republican countries that Australia is missing out on due to the fact that they're a constitutional monarchy? I searched up on this however couldn't find anything relevant.
3. International Organisations (such as NATO or the EU) but however Specific to Republics
Are there any republic-only international organisations that Australia could benefit from being part of? Once again, my Google searches didn't come up with anything.
So, please help me with proceeding with this idea in my debate. Thank you.
