There's all this talk about the perception of Australia in the world and that how the world sees Aus as being somehow subordinate to the UK.
They don't.
...I'm sorry to burst your bubble, but no one outside of Australia or the UK would care or even realise that we had changed our flag, nevermind care about it. No one in China, Chile or the Congo is going to look at Australia and somehow respect us more just because we got rid of the Union Jack.
History is history, and it can't be changed. Britain has shaped this country in so many ways, from giving us most of our laws, to giving us most of our people. It's something we chould be proud of or at least remember and not just something we should erase in some half arsed effort to gain more respect in some random countries that couldn't give two f*cks in the first place.
I agree that Australia should stand on its own two feet, but tbf, it already does. I've never met anyone that would confuse us with Britain, but plenty that recognise that Australia has its own unique culture. We should move forward confidently has a nation, but at the same time, not forget why and how we came to be here in the first place.
