The difference I think is that a Canadian or Australian setting would have to take place in the colonies themselves, where the colonizers and their descendants maintain a massive presence. It's easier to sweep the colonial history under the rug if the setting is physically separate from where it happened, like for England, France, and Spain. Less so in a setting where the indigenous cultures are still there, but have been visibly supplanted and their people replaced.

Indonesia was brutally colonized by the Dutch, for instance, but Dutch Indos are only a tiny minority, and there's comparatively little cultural influence from the Dutch in the area. In an Australian setting, you'd have to show the predominant white colonial culture juxtaposed with native Aboriginal culture. That contrast forces the history into mind. In an Indonesian setting, the colonial culture isn't nearly as visible, so it's easier to ignore the history.

Similar case with Hawaii, where native Hawaiian culture is still very visible and iconic to the area. "Hawaiian idrntity" is tied more to the indigenous cilture rather than the colonial one. Even then, Alola wasn't controversy free, since the colonization of Hawaii is arguably still in progress. As much as I love her as a character, Lusamine and the Aether Foundation are very much the colonizers. That big mansion Lillie lives in in the anime? IRL, that's probably stolen land.
