Might need to take it up with CASA, they decide what airspace is required. They also set the rules regarding doing an en route function and terminal function at the same time, last I heard it wasn't allowed (you can be dual rated but can't exercise both functions at the same time).
As has been pointed out many times, controllers will do whatever is asked from them, but time after time we see these "great ideas" turn to poo due to lack of resourcing (be that training, equipment, staff etc) and understanding on what is actually involved.
