Depends on your definition of "nice" I guess but you'd be making compromises for the first few years at least, particularly on a single wage. Housing can be very expensive but for instance Melbourne airport is outer suburban so the housing is more affordable in the area if you don't mind outer suburban.
There's no such thing as a "high grade" tower assignment- we're all paid the same and you start at the bottom and work your way up the payscales.
