Australia’s proximity to China is maybe affecting its western ideals. This is one of many things it’s done and doing recently to make it a less free country and this can only be a slippery slope which they are already sliding on.
South Korea spent much of the 20th century under military dictatorships, going from one military coup to another. Singapore's single-party system (with suspiciously fascist iconography[0]) is notorious for harsh authoritarianism. Japan today is a lot more liberal than it was a century ago, but their criminal conviction rate is too high to be believed and public support for the death penalty is around 80%. All three of these are nice countries in many respects, but I don't think any of them are particularly liberal by anglosphere standards.
