His fascism and bigotry aren't spilling over anywhere, Trump represents a mean streak in society that's dominated by wealth, eg, fascism. It's everywhere already, that's why non-Americans are focusing on Trump. You'll note that happens in anywhere defined by "Western society". Australia included. Hell, Qanon's founder didn't live in America.
I'm not saying any of this is good or right, but don't pretend your nation's fascists will slow down because of Trump. They won't. They were there already.
The same thing was happening back before WWII. Fascists existed in America before the war. They existed here after too. And Canada. And Australia, etc.
