If there is ABC movement from a powerful country, then those in the external country will want to use that to further their agenda to the degree that it is aligned with their own.
The CIA used to (and still does) try to push some kinds of narratives aboard, most prominently in the 'flower' revolutions in E. Europe, but much of the pop culture one's just happen 'organically'.
Particularly in the Anglosphere.
In Australia the anti lockdown / anti Vax stuff got shut down quite quickly.
Same goes for the BLM protests that tried it on without the right permits.
Kind of glad I don't have to put up with the same crap here or the media trying to call it peaceful.
I think it has a lot to do with the multi party system.
I don't have to align myself with one party or the other party, and all its polarising crap along with it. If one party has too much polarising rhetoric I can just pick a more moderate party.
I'm not saying this is good or bad, but I'm saying all sorts of movements cross the US border in an organic manner.
Edit: if you read the headlines in the Guardian or the Daily Mail, they mirror US issues to a great extent, much more so than they do in Germany or France, for example. Definitely the CBC in Canada. It's natural as the cultures are aligned.

Is Australia really a multi-party country. Seems like Australia, much like Canada, has two major parties at the federal level who take turns governing the country, and a bunch of smaller ones who have no power and no chance of ever getting into power.
Whilst the smaller parties / independents do not have a real chance to gain majority, they can still have a voice and oftentimes hold the balance of power. This leads to some claiming that these smaller players have a much bigger influence than they deserve.
This is what gives the multi party system its power, coalition forces diversity.
If the Greens have a policy that will get people to vote for them, then the Labor party has to pick that up as well or start haemorrhaging preferences. Ditto the Liberals and various lobbies like One Nation.
It is extremely difficult for the major Australian parties to ignore a minor party that has better policies. Although the majors are stable as a brand, the actual policy mix and strategy is quite dynamic and influenced by the minors.
You've obviously picked up some opinions from the media about how protests on a completely different hemisphere than yourself were.
