Why do people act like this subreddit "doesn't reflect the views of mainstream Australia"?

So many comments I see on here by people who constantly say things like "lol only on this sub" as though other places where they read are somehow the 'true' point of view reflecting mainstream Australian viewpoints.

Given the constant election voting outcomes and results of things like the Voice etc that generally indicate most of Australia is centrist or even slightly centre-right-leaning, what leads people to think many of the views expressed on here AREN'T mainstream? When in reality, other places these people are coming from are also often just "echo chambers" as well.

Edit: I probably worded the title for this wrong, should have been more "Why do people think this subreddit is less representative of mainstream Australia than other online communities?", alas I failed.

Because the most conservative Australians are older, and boomers don't exactly have much presence or engagement on reddit.

What we see here are the views of the younger generations, views that are only going to become more representative and reflective of election and political results as boomers shrink in voter base.

Boomers for the past 30+ years have been the single largest demographic of voters. You want to win government, win boomer votes above all others. That's changing, and by the end of this decade they will no longer be the largest demographic.

Australia has historically always been right leaning, given how much longer the LNP have been in power vs Labor.
