Australian Airline Hub

I've went through a few of the game worlds, and none of them seem to be a good place to start an Australian airline.

Which gameworld has a good and not full market in Australia? I'm looking to start an airline in Adelaide with flights from

Brisbane/Sydney > Adelaide > Perth and vice versa

Come to Aspern. Adelaide has more than 50% of slots free.
