The same way you do for any country, you ask, or look up information about it. The problem is that you're basing your entire concept on new stories reprinted in your nation based on their own filtering of our newsworthy stories. It's gone through at least two sets of filters - our nations and your nations - as to what is considered "newsworthy". Good news is not newsworthy, also they basically paraphrase what our debates are actually about, losing all context. e.g. the political dispute about the refugees who are detained (who actually make up e.g. 3-4% of all refugees here) loses all context when it's reported by journalists from another nation who don't know anything about what Australia is like (e.g. that many areas are dominated by non-anglo immigrants, and this is generally accepted by the vast majority of people of all races here).
e.g. if I only went off local Australian news about what America is like then start mouthing off "all Americans are like XYZ" then I expect that to be shot down by people who actually live there pretty quickly. Because we're in a different country, we get all America's "horror headlines" but we don't get the "feel good stories" that their own local news balances things with - we have our local "feel good stories" instead. As far as I know every American is constantly dodging bullet fire or armed robberies and being involved in major traffic accidents, going off local news about America. So, as much as America's own local media is already biased, we're getting literally a "hell on Earth" distilled version of American news here.
Basically, the mistake is in thinking that because you read what your local press is saying about some faraway place that they must know what they are talking about. How often do you read some tech article and think "this journalist doesn't know what the fuck they are talking about". Here's a hint: it's not just a problem with tech articles - you only notice because you are a techie. If they can't get tech articles right, where the knowledge can be gained locally and even through first-hand experience, then how much faith are you going to put on journalists to give you an unbiased idea about life in other countries. Hell, half the journalists can't even report what's happening in their own country without fucking the details up.
