The version of Australia's real history is mostly sanitised when it's taught in schools too, we were never taught of any of the Aboriginal massacres carried out by police. Australia also had a slave trade where thousands of Pacific Islanders were kidnapped and brought to Australia to work on the sugar cane plantations.

We never got taught that the British Royal family (who are actually Germans with ties to the Nazis) were some of the worlds biggest African slave traders either, even after slave trading trading was outlawed they kept doing it for about a hundred years, they just stopped docking the slave ships in Britain. A large part of their fortune was amassed by trading humans.
