Maybe all the trainers are Burglar class?
What? Who said that? In this day and age? Honestly!!
I would personally be happy if they didn't introduce any more new Pokémon for a while yet. I think it would be an interesting game, since Australia is famous for having more or less every kind of major environment, including tropics, rainforest, deserts, year-round snow. I think the routes would be ridiculously long since Austrailia is a freaking huge place.
Now this is just making me want to go to Aus right now...
PS - I *love* your in-game map!
