I don’t know about less conservative (I actually don’t know) but even the concepts of “conservative” and “right-wing” are different in the US. We don’t have much of that ingrained proudly-capitalist red scare rhetoric that’s normal in the US, comments like “free healthcare is socialist” would make most politically-aware Australians laugh, and make unaware Australians consider looking into socialism. We nationally don’t have a good opinion of the US, as far as I’ve seen, despite them being cultural and geopolitical allies to our government. We’re less prone to dynasties (Bush family, Clinton family) and electing actors (Reagan, Schwarzenegger, Trump), we have some expectation of professionalism.
