On paper, yes, you generally have less freedom being an expat here, versus a resident of your home country. Maybe "freedom" is the wrong word, and something like "personal liberation" would be better? I think it's just a bunch of small things, when rolled up, make for a big thing.
For example, you mentioned how great it was enjoying some prawns and a couple beers on the beach. I don't know about Aus, but there's no way you can do that in Canada. You can't serve people food or beer on the beach. You'd be shut down, arrested, and fined out the ass, and within hours of trying too.
You know what happens when someone wants to setup a little roadside shop, and sell soup? They buy a stall for $300, some food for say $100, then negotiate with a neighbor who has a corner lot to use their land, and go to work. That's it. You can't do that in Canada. Again, shutdown within hours.
And I could go on forever with small things like that. Again, take thousands of those small things, roll them up into one, and it definitely impacts society. Many things might not impact me personally, but they do impact everyone around me, their perception of reality, their personas, and so on, which all indirectly affect me, my perception of reality, etc. Whereas in Canada you're constantly surrounded by worried people who are trying to do the right thing, but are burdened down due to this and that, etc.
I don't know, probably not a good explanation, but best way I can describe it in words.
