Yes. We’re not interested in joining the EU. And we’re not interested in becoming a US state.
But trade doesn’t need to go all the way to DC. By plane, Sydney to LA is about - 13.5 hours. Sydney to Brussels is 20 hours. I imagine the difference is even greater for cargo ships, which can sail directly through the pacific. I have no idea how cargo goes from Australia to Europe. That sounds like a complex route.
As for trade, the US is important but they’re not our most important trading partner. China accounts for $326 billion aud in trade annually. If your numbers are right, that’s more than our trade with the US and Europe combined.
I suspect integrating into the EU single market wouldn’t be worth it for us. We’re not part of Europe. We’re not a European country.
