Australia has one drawback - living in this country is expensive and you will not have enough income from the signature company to cover all living expenses in this country.
Even though you list great things about Australia, you seem to be pointing out that you missed the main point.. which is the starting out with the idea of a place in which your income (from something like a signature campaign) and perhaps some other relatively modest means could allow you to have many if not most if not all of the things that you had listed, but in a place in which your income could sustain yourself.. and sure maybe there is a bit of a pie in the sky to suggest that there might be places that are like the west, but just not in the west so they cost way less.
