I've noticed a lot of sex workers (SWers) want PR. But it got me thinking about Australia, that is, aside for money, is Australia even that great?

I would never do it though but aside for the money, what's so good about Australia that SWers wanting PR is so common? Or is it just the money since I couldn't fathom growing up in an average country.

Edit: Only individuals satisfying both the criteria of 1) and 2) may answer this.
1) Australian citizenship through birthright
2) Raised in Australia.
