D1 - unless things have changed in the 7 months since I left - all controllers who have reached the same stage of their careers are paid the same money. Some get expedited advancement but the salary scales for GAAP, TMA, and radar towers are the same. Outstation towers may be slightly less but not a whole lot of less.
So if you were a PH TWR controller who was sent to Broome to only do D/E airspace you would not lose dollars, only that sense of well being that comes from being able to afford the rent!!
