Luckily this is much less the case in Australia - or pretty much any developed country.

It's still somewhat the case, but the propaganda in schools outside of the USA is much less than the propaganda on social media.

I had the uncommon privilege of attending a year of high school in Japan, and rest assured there is no lack of propaganda in other countries' schools, even if often by omission of truths.

I am not Australian, but I suspect high school textbooks are likely less than entirely forthright about sensitive subjects like Residential Schools and their role in settler-colonialism.
