It's a very approximate list! But since you mention it.. the migrant issue is an outlier I think. It's shameful, but an outlier (I'm Australian btw). Generally we mostly do a decent job. Manus Island makes my blood boil, but we've spent billions trying to stop the solomon islanders killing each other too (RAMSI). The aboriginal health crisis is actually worse IMO, not that it's in the news.
I put Japan there because of its more or less systematic discrimination against people of korean ancestry, lack of support for the economically disadvantaged (eg. freeters, NEET), generally outdated attitudes to women and of course their 99% conviction rate criminal justice system. But honestly, you could make a case either way. Japan's not a bad country in aggregate.
